Many folks have been asking for exam recalls to be emailed to them. Fortunately, your colleagues have previously posted – and continue to post – recall questions from recent exams. These are located throughout the discussion areas. I continue to compile them all in this area. If you have additional questions to contribute, please do so and you will be credited. Pay it forward and be a good human citizen! Thank you!

BHCG tumor marker for what? Not sure but I answered chorocarcinoma. Cos the three choices were pancreatic, colon and lungs
5HIAA carcinoid tumors
I had 5 bb panels (was thinking maybe this was the reason I failed. Although I did understand but the questions were a bit confusing. Not sure with my answers)
Proteus vulgaris and mirabilis indole tests
Bb and Heme Case studies
Hydatid cyst fluid
Antacid overdose? What lab test should you conduct?
I took the ASCP MLS exam yesterday for the third time and passed. I went through quite a few recalls and did a lot of lab CE (scoring around 80 for the regular 100 question mode and 75 on the adaptive tests) Here is what I can remember:
-Prolonged PT, PTT, and thrombin after collecting from catheter= heparin contamination
– Question with mixing study that was performed with a prolonged PTT that couldn’t be corrected=
-Another question with two pt’s ran in duplicate (PT and PTT). The PTT seemed to always be prolonged but PT looked ok= I picked check the CaCl/phospholipid reagent delivery
– Patient is on coumadin therapy, what will be affected= Decreased protein C
-Lot’s of stomatocytes= liver disease
-Burr cells= uremia
-Picture of target cells with hemoglobin C crystals. The white count was high on instrument 1, so a second instrument was used with a stronger lysing agent, and the white count was corrected= I picked anti-lysing target cells are what increased the white count.
-A sodium citrate tube was drawn for a HCT on a pt but the hematocrit was abnormal. Options were recollect in heparin (what I picked), recollect with increased anticoagulant, recollect with decreased anticoagulant, etc.
-Question that gives a red blood cells count, HGB, and HCT. I did the rule of 3 and found that the HGB didn’t meet the rule of 3 because it was too high= I picked check for lipemia (elevates HGB)
-Picture of PBS with an elevated reticulocyte count and howell jolly bodies in the RBC’s.= I picked stain with prussian blue stain in order to see the retic nuclei
-what is composed of DNA?=howell jolly bodies
-what falsely decreases ESR=vibration
-ESR is increased, what is NOT a cause=I picked macrocytes because macrocytes don’t rouleux. Other options were rouleux, increased globulins, inflammation, etc.
-Question about lactic acid collection=separate from serum and put on ice
-Question about coefficient of variation
-Carbon dioxide electrode measures what?= pH
-Question about patient that had a random glucose >200 and an FPG >126. What do you do next?= I picked repeat the FPG. Other options were diagnose with diabetes mellitus, perform OGTT, etc.
-Man tested positive for syphilis 2 years ago but may have again, how would you test him?-RPR
-Question with a graph with 3 peaks related to a bacterial infection= I picked that the first peak was the antigen in the stool, the second peak was IgM (goes up and then down quickly), and the third peak was IgG (goes up and levels off a little).
-Person tested positive for HIV-1 and HIV-2 but western blot was indeterminate. What do you do?= I picked do CD4 count. Other options were repeat western blot, repeat HIV-2, etc.
-Blood Bank- It felt like I had a lot of questions
– 1 small antibody ID panel. The antibodies that matched up were Lewis A Lewis B. Question asked about the characteristics of the antibodies.= I picked that they are lipids absorbed onto RBC from plasma.
– There was a positive DAT on cord blood; mother is Rh pos, baby is Rh neg. What is most likely coating the baby’s red cells?= I picked K (kell). Other options were A&B, D, Lewis, etc.
-Picture of what looks like cold agglutinins (I got this picture 2 different times during the test).= The first time I picked cold reacting antibody. The second time the options were different so I went with Paroxysmal cold hemoglobinuria. Mycoplasma infection was an option but there wasn’t a lot of WBC’s in the picture so I didn’t pick Mycoplasma.
-What phase can rouleux not be detected in?= I picked AHG phase because a positive 37C, negative AHG, and positive auto=rouleux
-Picture of ABO type with mixed field reaction in the forward type= I picked that patient was transfused with O blood
-Picture of AB in forward reaction, and weak reactions in back type= I picked incubate at room temp because probably cold agglutinins
-Question about an adsorption that had been done twice, and antibody screen is positive=I picked perform antibody ID panel
-If a patient is type A with Lewis a+b- what substance will be on their red cells= I picked Lewis a but other options were (A, Lea), (H, A, Lea), (Lea,Leb), etc.
-Micro- no parasite questions, 2 mycology questions
– Only 1 micro picture. Bile esculin +, NaCl-, alpha hemolytic, looked like a strep=Group D strep gallolyticus/bovis
-TSI slant K/A H2S+, PD-,= Salmonella antisera was only organism that fit
-Question with lactose fermenter, ODC+, lysine -, etc.=Enterobacter cloaca but I’m not sure
-CSF storage= incubate at 35C
-Hair perforation test= Trichophyton metagrophyte and T. rubrum
-Good way to detect Legionella infection=antigen detection in urine
-Question about a lesion on an arm= I picked sporothrix schenckii but I’m not sure. Other options were cryptosporidium, microsporum, etc.
-Mycoplasma can’t be treated with penicillin= no cell wall

Passed the MLS ASCPi exam! I can say it was hard but with good study materials and prayers, inshallah you will pass. I used the Polansky cards then the Betty Theriot book for refresher as it was 8 years ago since i took the national board exam for RMT in my country – Philippines. I highly advice you to avail of Labce and do at least 100 exam daily. Both the computer adaptive and the Review mode. Read the explanations at the end and take note of them. Identify subjects you are weak and concentrate more on them. For subjects you are good at, give lesser time to them. Also, take notes of the recalls in this wordsology site. Try to memorize them, they might appear in your exam just like mine. They are worth points! These could save you. Coagulations, Blood disorders, Leukemia and Mycology and Biochemicals identification are things that appeared in my exam. The subjects i’m very weak at. They come on a situational format – like what will you do? What do you expect? Here are my recalls…
After ingesting moth balls what you see in PBS? Heinz Bodies
AB Rh: POSITIVE patient has reaction on forward A 4+ and B 1+ Rh 4+. What will you report? I answered AB Rh +
Gram negative cocci after a jaw surgey? Veilonella spp
QC on BhCG has weak positive in QC + and negative on QC neg what will you release? Release as positive BhCG.
MCV day 1: 78, MCV day 2: 77 MCV day 3: 76 MCV day 4: 62, what is the probable reason? Wrong patient.
Which leukemia + for Philadelphia?
High LAP score?
Low LAP score?
Smudge cells usually seen in? ALL
A picture of alternaria fungus.
A picture of Candida geothricum.
Olive oil for. M.furfur
Youre given a list of cv, which of them is best?
Given lab results, which one is suggestive of Lactic acidosis?
Calculate how many units of blood to be taken given the antibodies and their percentages.
Calculate corrected WBC given the retics and WBC count. In this case the differential was only 50. Im not sure but what i did is: WBC Uncorrected x 50 / nucleated RBC x 50. I did the 100 the answere is not on d choices, but when i calculated using 50 as factor, the answer was on the choices.
Study antibodies of HAV.
RPR negative FTABS +? Release positive.
Cryoprecipitate and FFP allowable time of use if Ref. temp is 4 degree celcius. Based on AABB standard.
CK MB normal, Tn I is high? Myocardial infarct.
First to increase in MI? Myoglobin.
Study electrophoresis: Albumin, alpha 1, alpha2, beta, globulin.. Which is high given the disease, or the other way around.
There was a fungal colony which is violet to purple in color on the plate. Im not sure, i chose Fusarium.
Biochemicals of Salmonella typhimurium and Kleb. oxytoca
I had one simple BB panel. it was positive for Anti-Fya and anti-E.

Study well but pray harder! Prayers can move mountains seas and skies. Be positive. God will grant the desires of your heart . GOOD Luck
Passed the ASCP MLS exam last week. I would like to thank Sohail website, it helped me a lot to pass the exam especially the micro diagrams and recalls, i got like 10 questions from the recalls. Here are the questions that I could remember: mycoplasma pneumoniae 2 weeks titer, RhIg 50 mL fmh what is the dosage? Howel jolly pic, diazo caffeine what is unconjugated and conjugated? 395 glucose, 4.2 K, what is the K after insulin if the glucose is 215? CLL which lymph T cells or B cells? Pagets syndrome pH 9.6, hdl- heparin manganese, which one should be deferred?-hct 37. Bartonella- cat scratch curved gram neg , enhance anaerobes- vitamin k and hemin, what reagent on fecal occult blood? – hydrogen peroxide, chronic myelogenous leukemia, compute coefficient variation which value is more accurate?-choose the lowest value, pic of aggregation test, cushing syndrome- increased cortisol, decreased acth, chronic anemia disease- increased iron, increased tibc, acetaminophen poisoning what to test? – I picked bun and creatinine, 40 ml per min creatinine clearance what is expected? – increased bun. Pt and ptt controls were abnormal qc repeated ptt was normal what will you do? – replace thromboplastin.identify Hep B profile if a person is pos on hep b core, hep b suface ab, hep b e ab, i picked past infection. I had a lot of bloodbank panels, lots of micro questions. I used Harr, lab ce, ciulla, polansky and the yellow book. Good luck to the future examinees:)
I just took my test today. I passed! I studied 4 months for this test. After hearing many people from class saying that thetest was super hard and that they didnt pass I panicked. Maybe I overstudied but I don’t have the money or patience to study twice for the test. I have read every single thing on this forum and website. I cannot emphasize enough how important it is that you utilize this website to the fullest. Even if you don’t manage to study all of BOC HARR or Bottom line. This website and bottom line will have you covered. I am not sure that I can add anything else to what has already been stated by previous posts so I will attempt to make a useful contribution.
-Discrepancies, study them. A useful mnemonic device I used for ABO discrepancies was “EMMMA”:
– Lewis- secretors vs nonsecretors. Know everything about them
– Make sense of who can and can’t donate and why
-Weak D vs Partial D
Bottom line has this section really well summarized. study that plus this site’s section and you should be set. BOC also helped.
Blood bank was the heaviest area for me. If you have a hard time with antibodies use this video :https://www.youtube.com/watch?v=mvGC5M0ICCs it helped me alot on the test.
Micro: This site’s charts. Period. Don’t even bother looking into your micro textbook, along with the recalls the charts summarize it all. Only thing extra is bottom line’s TSI reactions.
Chem: I literally only had recall questions from here. A mnemonic I used was U C B U “yoU C(see) Bulls**t”
U- unconjugated billirubin: Elevated in pre hepatic and post hepatic or billary obstruction
C- conjugated billirubin: elevated in hepatic and post hepatic
B- billirubin: elevated in hepatic and post hepatic
U- urobillinogen: Elevated in pre-hep and hepatic. Decreased in billiary obstruction
Heme: Know your PT APTT ranges and MIXING STUDIES! and lupus anticoagulant.
Immunology: I had alot of HIV, just know that Wetern Blot is used for confirmation.
Urinalysis: know your dipsticks like everyone else said
Immunology: HIV, and ANAs
Finally know basic laboratory procedures. MOST IMPORTANTLY however is that you are able to think critically. A lot of questions are not just based on pure facts, you have to think and act upon your knowledge. This is what would happen in real life, you will somtimes be caught in a situation where you know the theory but have to apply it in another situation. So, relax, breathe and make sure you spend your time on what you know. If you have no idea about a question, PICK B and move on! you could use that time and brain power on things that will require you to think based on knowledge you already have. All in all I used all of the resources: BOC, Lab CE, HARR, this site, Bottoms line, Success, and Polansky cards. If you study enough you should be just fine. If you are scoring between 60 and 70ish on lab CE thats a good indicator, but as alwasy stick to this website and bttom line. Good luck!

I just took my ASCP and passed on a first try. I cant thank the creator of this website enough. I used wordsolgy for study tips, exam strategy and high yield notes. I categorized and reviewed almost all the recall questions, the process was time consuming but It paid off. I completed my rotation 5 months ago and so I am not as fresh on the material. I studied for two months: a couple of hours during the first month and about 4 hours a day the second month. The material I used: this website, bottom line approach ( specially tables, graphs, memory aid), the success book for areas that weren’t well covered in the bottom line book. I subscribed to LabCe and completed 5 adaptive exams scoring 52-55% average difficulty 5.5, I also subscribed to PassASCP.org but their questions are all mentioned as recall questions from this website.
My thoughts on the exam: it was a fair exam, most of my questions were blood bank. I strongly encourage anyone to go through the recall questions I have seen about 30-35 questions that were from this website.
Blood bank: focused on discrepancy and DAT
Micro/Mycology: high yield notes specially enterobacterace chart, I got about 9 questions from both areas mostly were recalls
Urinalysis: strip tests and discrepancy
Chem/Immunology: memorize bilirubin (conjugated and unconjugated), urobiloinogen pre,hepatic and post hepatic results.
1)what causes postprandial lipemia
2)for some measurement (can’t remember exactly) the absorbance cutoff is0.700 and the measured viral antigen is 0.300 what does this mean? +/- or undetermined results.
3)patient fasting glucose is 128 and 2hr level is 200something.What should be done? Repeat test, do glucose tolerance… can’t remember other choices.
4) Cushing syndrome ACTH and Cortisol levels
5)Monocytosis seen in what? TB, mononucleosis, hypersensitivity.
6) young woman with sore throat, malaise and cervical lymphadenopathy then given antigen or antibody levels to CMV and EBV and had to determine if it is coinfection, CMV or EBV.
7) One ANA question with fluorescing speckled and centromere patter and I think it was CREST and scleroderma.
8) patient prostate gland was remove a year ago due to cancer, yet his current PSA is positive? Is the test not specific, is the sample not his, his cancer came back
1)There is a picture that I came across in two different questions and I think it was hemagglutinin
2)Reduced EPO is due to what? PV or secondary PV
4)Megakaryocyte CD marker
5)lupus anti coag what does it do
6)recognize DIC lab results
7)Manual RBC calculation
8)MI patient who was treated with streptokinase. Which of the results sugesst that treatment wasn’t successful. PT 12, PT 25,PTT 200 or D-dimer +
I went into test center scared half to death because of “all the situational questions” but frankly, they were all one line questions giving the most minimal information. I am an over thinker, very well versed in what MTs actually do in their labs, what text books say to do, and also in all sorts of far-out alternative theories, so these minimal-info questions drove me crazy. Also, my test gave me definitions as choices in place of the actual organism or condition. Some questions were just so easy that I wondered if there was a hidden meaning. Example of definition: antibody R/O panel showing all reactivity in IS phase nothing at 37/AHG, so choices included cells destroyed by enzymes, sialo (or something like that) antigens, and glycoproteins adsorbed onto RBC. As the panel reviewed perfect reactivity in Lewis and mixed reactivity with M & N, I chose the glycoproteins adsorbed as that is definition of Lewis. Another was exact definition of FV Leiden. But I was getting hard questions toward the end, like figuring out the most likely antibody for a certain Rh phenotype – by then I was just tired, not that I couldn’t figure it out. I had to remember the Rh antigen frequency (D, c E, C e most frequent to least) . Also my test had a good third of questions all from these recalls, I had read the recalls back in August but forgot about them, but they must have sunk in, after all. So my bit of advice, yes yes, do go over the high yield notes on this site’s strategies, do know as much as you can about the highest yielding stuff, be well rested! Write down reminders on your white-board to clear your mind. I got a TP/FN question, wrote down the equation provided just in case and got a similar question later with no equation provided! I had the same slide 2x of cold agglutinin, asking what might this reflect (Mycoplasma) and then again, what condition might lead to this cold agglutinin (PCH as Mycoplasma was not a choice this time). I had at least 6 questions using babies as patients so I had to really know what might affect babies differently from adults, their normal clinical ranges. I’d say, because of all these recalls, the high yield notes, my own note taking, my test was not actually hard, and there were only 5 questions where I had never heard of condition/situation and had to guess. My own problem is I’m used to a ton of information in case studies, and it was hard for me to just look at the question as is.
Dino C: I took my MLS Oct 14,2016 for first time & passed. I agree with you on hard questions persisting toward the end. I found that a good one-third to half of my total questions actually reflected most of the recalls posted on Wordsology. I had read the recalls back in Aug, wrote many of them down figuring I’d double-check their answers but forgot, as I was deep in studying for everything else. So most of the recalls must have sunk in, after all. Anyway, I got a few easy questions toward the end, like the no-brainer: what is the analyte for GFR. But question #100 was analyzing 4 donors for a patient with DCeDCe phenotype, and which antibody most likely causing Rx in 2 of the donors. I had to take time working that out because by then I was tired, not because I didn’t know how to do it. And had run out of space on my white board. My really “hard” questions in hematology, micro & BB were around questions 10 -50. Because of all the recalls occurring in my exam, I never found the MLS to be that hard overall. Not a single leukemia, acid-base or which agar to choose. I was more than prepared for those😦
Where are urine crystals formed? Options 1)where distaled tubules, proximal tubules, loop of henle or bladder.
2) 2 questions about someone who had Duffy antibody but no longer has it. They need blood what do you do? Options where cross match only or do pannel are the ones I remember.
3) which is used as control in micro? It was something for ecloi vs something else for indole test. options for urease, lysine?
4) question about adh in chemistry and water
5) questions about sodium and chloride
6) question about Mcv
7) coefficient of variation formula
8) what is Tsh used for? Some of the options were to detect thyroid cancer, something about t4
9) where is lymphocyte from? Not bone marrow but another one I forgot but bone marrow was option.
10) something about Sudan stain and what’s it used for? Options were lipids, fats, proteins and something else
I had a lot of micro and blood bank questions more than anything else.
Resources I used to study: this site, labCE, Harr, Polansky review cards, sketchymicro, bottom line approach (highly recommended!!!)
Questions I remember:
1) Transudate definition (is it purulent, high cellular WBC count, etc?)
2) Urine color matching choose which one is correct ( I put port wine- porphyrin)
3) Which is more significant found in urine (pH 8.0, +1 protein, bilirubin +)
4) Know how to read immunodiffusion arcs (identity, partial, non-identity)
5) If you see band at start of serum protein electrophoresis what should you do?
A. report as abnormal
B. perform immunodiffusion
C. check to make sure it’s serum
6) Low serum iron, low TIBC, normal ferritin? anemia of chronic disease
8) picture of enterobius vermicularis egg- use cellophane tape
9) Sensitivity vs specificity
10) several metabolic/respiratory alkalosis and acidosis questions
11) correlate RBC morphology with disease
12) hyaline casts may be confused with? mucus, fats or crystals (I put mucus)
13) semen analysis (abstinence, lubrication?)
14) calcium ion electrode measures what?
15) bronchiolitis in young children and immunocompromised- respiratory syncytial virus
16) Diphtheria- use loeffler and tinsdale tellurite

18) 3-4 antibody panels
19) cross- match unit calculation
For example: How many units of group O RBC units should you phenotype, in order to fulfill the request for two cross-matched units?
K negative 91%, Fya negative 37%
STEP 1: 0.91 x 0.37 = 0.33
STEP 2: Divide 1 by the number you calculated in first step 1/0.33 = 3
Since you need to cross-match 2 units, need to pull 3×2 = 6 units
20) triglyceride calculation ( cholesterol = LDL + HDL + VLDL) ***VLDL = TG/5
21) tumor marker for colon cancer- CEA
Passed the ASCP on first try! I want to thank Sohail for creating this website and other people for their recalls. I got maybe 5-10 questions from the recalls. I think my test was very hard… Thought I wasn’t going to pass… It was a mix of everything and there were some surprises that I had absolutely no clue… No questions on metabolic/ respiratory syndromes, no parasitology, no UA cast pic, 1 blood bank panel, 1 calculation, 1 ANA. The questions were pretty random and some came out of no where (unlike some people who had mostly BB or micro) and didn’t cover the topics that I studied the most/ most confident in. Where did the antibody ID, blood components, and Hematology questions go?!
The study materials I used were Harr, Bottom Line Approach, BOC, Labce, Polansky cards, high yield notes from here and my class notes. In my opinion, Labce is helpful only to a certain extent. You can get an idea of how well you understand the concepts but the questions do repeat and some were too difficult and irrelevant for the board exam. BOC book is okay because the questions are worded similar to the actual test. Study the recall questions!

I want to thank God 1st,the creator of this site and everyone who submitted recall question more than 50% of my question were questions others mentioned on this site, indeed and BOC book. I took the time and wrote all the recall question down and put then into each category. Study study study. Know the small details. I used labce, Harr review book, bottom line approach, BOC, the Polansky flash card. For microbiology all you need is the height yield note found on this website.

I passed my ASCP exam today. The high yield notes helped! As well as the passing strategy posted. I used Lab Ce did about 1300 questions mainly scoring between 60-70 on the review mode and 52-60 on the adaptive mode.
I got mainly hematology and blood banking and just a few chemistry and about one lab management question.. To those who will be sitting the exam my Recall notes are;
– make sure you know the antibody panel and how to identify the clinical significant ones I got about 2 panels. Use the one shown here in wordsology.
– make sure you know how to interpret ABO blood typing. I got a question asking if Anti A is pos and Anit B neg and A1 cell Pos and B cells Pos. what should the technologist report. Also I got a question asking what should the technologist do if Anti A is mixed feel and Anti B is Pos and A1 cell Pos how would you interpret it. Also got tuns of questions about ABO discrepancies. If there is a autoantibody reacting only at room temperature which would it be. ect
I was asked to calculate
– Molarity -creat clearance- osmolarity- anion gap, coefficient of variation, and I had to know the metabolic syndrome and the conditions that can cause them. LDL calculation as well.
– tons of questions!
know the different in distinguishing K.pnemoniae from K. oxytoca. know about the differential medias. Thanks to the high yield notes most of the questions surrounded them.
know how to calculate MVC, MCHC, Manual differentials or wcb, rbc, and one of platelet was there too.know the different leukemia CML, ALL and lymphomas and how to distinguish them.
those are my recall in a nut shell. HIGH YIELD NOTES HELPED
Hello everyone! I took my exam yesterday and passed! This website was super helpful, especially the high yield notes for micro and chemistry. I only studied for two weeks after finishing my program and I used the Harr book, Polansky notecards, and LabCE.
1.What antigens are found in the saliva of group A, Le(a+b-) individuals? – Le a (other options included A, H, Le b in different combos)
2. Given a mini panel of antibody reactions. The serum is tested against Group 0 RBCs and cord cells. Reacts with all adult cells, no reaction with cord cells. What antibody? – Anti-I
3. Given panel of antibody reactions, have to determine which ones are causing the reaction and choose the choice that corresponds to them. – In mine, the antibodies were anti-Le a and Le b, but the answer to the question was ‘Is absorbed from the serum onto red cells.’
4. I had 2 questions with the same picture, a cold agglutinin picture. The first question asked what disease/infection it was associated with (Mycoplasma pneumoniae) and the second asked what would cause this blood picture (cold reacting antibodies).
5. Blood comes up positive for HTLV-I/II, what do you do next? – I put repeat the test that was just run. (It said which test in the question, I believe it was EIA, so ‘repeat EIA,’ but I’m not 100% sure. Other options were western blot, etc.)
6. O neg, Rh pos patient now has a positive DAT. What will their typing results look like now? Includes Rh control. – I chose the answer where everything was negative except the Rh control was positive.
7. Which antibody degrades upon standing, making it hard to detect? – I didn’t know the answer. I think I chose Lewis. CW was an option and I don’t remember the rest.
8. Lots of discrepancies, either due to ABO or reagents/technique, but all situational. I don’t know how else to prepare yourself for them other than knowing the basics well and being able to apply them to reason your way through.
9. Given mother blood type (AB-) and baby type (O+), what do you do next? – Since O blood type is impossible from AB mom, get a new heelstick from baby. Other options were get a sample from father, administer RhIg.
10. Mixed field reaction observed. What caused it? – I chose transfusion with O cells.
11. Donor deferral question
1. ANA pattern, asked what antibody would make that pattern.
2. Patient comes in with mild flu-like symptoms. Given table with IgG and IgM titer values for EBV, CMV and toxoplasma. Have to determine if primary infection with just one or coinfection of EBV, CMV.
3. Biggest problem with PCR? – I chose contamination with nucleotides.
4. What HBV disease marker is found in individuals with a past infection? – HbcAb

4. Enterobacter, given description of reactions – can’t remember if the species was cloacae or aerogenes, both were options. Other options were K. pneumo and oxytoca.
5. Following a throat infection, patient is having kidney problems. What bacteria causing it? – S. pyogenes, other strep species as other options.
6. Patient has walking pneumoniae and is prescribed penicillin. 2 weeks later, still sick. What happened? – Bacteria produces a beta lactamase.

11. Latex agglutination for S. aureus – Protein A and clumping factor
12. Given TSI results, what do you report? – The results pointed to Salmonella, so I chose ‘do Salmonella typing’ but another choice was to call the Dr. and immediately report Salmonella type organism. Others were, report normal fecal flora and do Shigella typing.
1. Burr cells blood picture – Uremia
2. Stomatocytes blood picture – Liver disease
3. Badly discolored blood picture with very spiky cells. What caused this? – Slide not dry
4. Retic count 18.3% along with really messed up blood picture. What do you do next? – Heinz body stain (Supravital stain was also an option)
5. Iatrogenic anemia – due to excessive blood draws.
6. WBC and platelet count normal. Normocytic, normochromic anemia. RBC count very low and retic % is 0.1. – Pure red cell aplasia. Pretty sure I had never heard of this before the exam, but I figured it out. Other options included aplastic anemia.
7. HgbA1C values would be decreased in – hemolysis/hemolytic anemia
8. What is the second, irreversible step in platelet aggregation studies? Or something like that. – I had no idea, guessed change in platelet shape. Upon googling, it seems ‘release of nucleotides’ or something related would be correct.
9. Know about the reagents used for PT and PTT in the automated coag studies. I had 2 questions where the controls were off (and therefore patient results were off) but you needed to know which reagent to replace.
10. What cell type is increased in mononucleosis? – Lymphs

……..a lot of “what do you perform next questions” related to BB so brush up on panels, DAT, IAT and discrepancies
Well I just passed the MLT (ASCP) registry today. I had to cram so I did 1000 questions from LabCE and roughly 300 from the BOC ASCP book. I felt that the BOC practice questions were closer matching to the registry. The reasons given in the BOC guide are poor though so if you need any reasoning for answers then LabCE is definitely superior.
Here are my recalls from the test:
Differentiating non-Lancefield streps
Transfusion testing requirements
Elution, adsorption, absorption
Immunological testing types and methods
Pre, post, and hepatic jaundice (unconjugated, conjugated, bilirubinuria, urobilinogen, etc in each)
Gold standard chemistry tests, methods, and reagents used in them
DIC and MAHA characteristics and complications
Renin angiotensin system
Type 1-4 hypersensitivity reactions
Coagulation studies and factor deficiencies
Inhibitors and what they inhibit in micro media
Urinary casts and associated conditions
ALL, AML, CML
Which preservatives are best for which stage of parasite and source of specimen.
Mycoplasma- why it doesn’t stain
Mycobacterium- kinyon stain, auramine stain sensitivity, fast/ slow growers, scotochtomogen definition.
campylobacter pic, it’s growth condition,
Common urine isolate
Pork associated organism
Diff btw Proteus mirabilis& vulgaris
Gram pos cocci pics, other test if not agg pos.
Vitek ms definition, (can’t remember clearly but second question goes like – cannot differentiate btw s. Pneumo and given options)
**SURE POINTS: Heinz bodies (there were two questions with the exact picture in my exam, I answered G6PD deficiency and anti-malarial drug (now this might be a bit confusing bec the one I had have hypersegmentation, ovalocytes and tear drop cell; focus on the HEINZ BODIES!)
Klebsiella oxytoca (indole + as compared to K. pneumonia which is -) I also recommend Sohail’s notes on Enterobacteriaceae (GNB; all of the high yield notes really, they were all very helpful! memorize them if you can)
Alnernaria microscopic picture
Alkaline ph (9.4) I chose Paget’s disease bec of ALP.
Virus transported for 92 hours or something = Lyophilized (I’ve read this recall here, thank you so much!)
Olive oil = Malassezia furfur
CK (normal), cT (elevated) = Acute myocardial infarction (don’t be confused, since troponins increase faster than CK, this findings can be possible). Order of increase/peak: MTCAL (myoglobin, troponin, CK-MB, AST, LDH)
Bilirubin, Urobilinogen values (what disease association do they inc or dec)
ALP = obstruction
Chronic hepatitis = anti-smooth muscle antibody
Releases heparin/histamine = Basophils/mast cells
If Se and Le genes are both inherited, what phenotype? = Le(a-b+)
Pheochromocytoma = test for METANEPHRINE
Urinalysis results increase RBC (also strongly positive in strip) BUT neg in almost all of it = glomerulonephritis
Another one is almost all were positive in rgt strip and in microscopy, but the highlight was the presence of waxy cast so I chose= Nephrotic syndrome/dse
End stage of degeneration (renal failure) = waxy cast
HgbA1c decrease in = hemolysis (hemolytic anemia)
Lipoprotein that transport the majority of cholesterol=LDL
VLDL (endogenous triglycerides); Chylomicrons (exogenous TAG)
Gram neg cocci present after jaw surgery= Veillonella
Micrococcus = Resistance to Furazolidone
Tap water bacillus=Mycobacterium gordonae
Examination of semen sample, can proceed to sperm count = once the liquefaction is complete
Alpha thalassemia = Hgb Bart/Major (other choices were hgb D, sickle cell, etc)
Aeromonas hydrophila =GNB A/A G(+) on TSI, oxidase +
Procainamide = NAPA
Main metabolite of cocaine = benzoylecgonine
Type 1 hypersensitivity stimulated by = IgE
**Calculations: RhIg, Creatinine Clearance,
**NOT QUITE SURE: Graph of ECA (Epinephrine, Collagen and ADP), two of them changed from 0 (either inc or dec), the other one is just 0. They will ask you which ones are normal/abnormal
They wavelength of the spectro was set to 540 but for some reason the staff keeps getting erroneous (higher than the normal) transmittance, what seemed to be the problem? I chose halogen quartz as being the problem
I’ve read this from some of the recalls posted, about the calculation of potassium? Upon administration of insulin, the glucose decreased, find the value of potassium (given values of insulin and glucose, I don’t know the sol’n, please look for it if you can, I ignored this and then it appeared on my exam, haha tragic)
**other pointers to study/focus : Ab panel/ID, RhIg computation, ABO discrepancies; Bilirubin, Urobilinogen (Pre-hepatic, Hepatic, Post-hepatic), Acid Base Balance (metabolic/resp-acidosis/alkalosis); Sensitivity(TP)/Specificity(TN); ANA patterns. They were generous with the normal values, so you just have to take note of the abnormal results. Don’t be scared with the long questions or results. Just focused on the abnormal ones and also with pt history.

What would be the dilution in tube F?
Passed the MLS Exam. Thank you for this website! I wanted to let everyone know that it is good to know reference ranges. I noticed sometimes they give them to you and sometimes they don’t (HCO3, PCO2, BUN, Ca, etc). I got a ton of blood bank, hardly any micro, about 4 mycology (a recall question about zygomycete = sporangiospore). I also got calculations for Creatinine Clearance, Hemocytometer count (if they show you squares, make sure you take into account both sides of the hemocytometer). Bacillus anthras reactions were on there (non-motile, non hemolytic, catalase positive etc.) I got a picture with pappeinheimer bodies ( poor pictures). I also got a picture that looked like a slide with really prominent burr cells (abnormally sharp looking burr cells) and it asked what could have caused it, I am not sure of the answer but I picked that the slide was not dry. I also got what is TP+TP=FN I had to pick what is was (sensitivity). Another picture that looked like Heinz bodies and asked what stain to use (answer was Heinz body stain). There were a lot of small panels for blood bank. Know what the RBC inclusions are made of (DNA, RNA, Hgb). A question about what fungus you can test with hair ( I picked Microsporum audounii) There was a question about Micrococci (answer Resistant to fluconazol). Rapid latex test for Staphylococcus aureus and what it’s detecting. Something about Sodium dithionate and sickle cell (I chose severe anemia). I had to Identify a picture with Blastomyces Dermatiditis. Know when to do an elution, adsorption, descreptancies like when to test with Anti-A1. Know the difference between in Blood Bank reactions with PCH, Polyagglutinine. Know if HDN is caused by Anti-D or ABO group. Know K antigen frequency and if it will cause a reaction. Asked a question about HIV. Know the different types of electrophoresis, had some situational questions about Multiple Myeloma and whether to test with a different type before confirmation. I also wanted to let you guys know that this was my second attempt and I felt more prepared than the first time. I used Robert Harr and Clinical Lab Science Review Fifth edition plus all recall questions and charts.
Px chem result, you’ll see he has metabolic acidosis, what test are you going to order next, do you test for salicylate or lead poisoning?
Graph which shows the order of serologic markers for hepa a; which is the correct one
Antibody panel answer is the one with anti fya
Picture of tear drop cell, bilirubin crystals, burr cells.
A lot of mycology questions, describe histoplasma, molds that needs olive oil, what is the hair something test use for to differentiate 2 fungi
For those who are preparing to take this exam, please make sure you look at the questions at the back of each chapter of the “Bottom line Approach” . I have got about 20 questions from and many questions from “Actual Question” of this Website
CHEM…analyes elevated…which disease?(ALP-Paget`s bone,bilrubin-obstruction or liver disease,primaryhypothyroidism,skeletal muscle injury etc.)
HEMATO…smear with cells(H-J bodies,Heinz),which anemia from results?corrected wbc count,mixing studies,RBCindices.thalassemia hbs
Bld.Bank……3,4 abdy panels,storage and life time for cryoppt n ffp
MICRO…reaction given,find organism…(kleb.oxytocca,strep gp A,E.rhusipathiae,Chry.meningosepticum)
OTHERS…nephrotic syndrome(fatty cast)aminoaciduria(cysteine)ANAflourscent pattern,CV calculation,PCR components,procainaide assay….
For the ASCP certification the questions I received were mainly Blood Bank (LOTS of DATs, If mother is type A- and baby is B+ what is the most likely cause of a HDFN?, What is the next step to determine if the reaction is due to Rh or ABO discrepancy? Know how to recognize common discrepancies, etc.)
-Lots of Microbiology questions. The flow charts helped me SO much here. Even if I wasn’t sure of the answer, I was able to eliminate wrong answers to reach a conclusion.
-I got 4 questions regarding RPR’s and VDRLs.
-1 question over parasitology
-A question that showed various titers of IgG and IgM for CMV and EBV and you were to determine if it was an active infection of both or just one of the viruses
– 1 or 2 questions regarding Westgard rules and a graph
– Other subjects I remember: Cushing’s Disease, Metabolic/ Respiratory reactions (Bottom line approach makes it easy), Thyroid diseases, ANA, Specificity vs Sensitivity, Bombay phenotype
Most of the questions are phrased differently than LabCE though. They are very situational (Ex. A nurse draws a tube of blood for testing but is left out for 12 hours what tests can be run or do you reject it? Your controls are out of range what could be the cause? Do you continue and process patient samples?) .
i just passed my MLS exam! this site was of big help! i got A LOT of blood bank questions especially about DAT and ABO discrepancies. i also had a bunch of questions where they show you a blood picture and you choose the disease associated with it (ex: burr cells – uremia). i had 2 questions about urinary casts. i had one about platelet aggregation studies. pcs steps. rbc inclusion associated when a toddler ingests a moth ball (naphthalene) — i believe the answer is Heinz bodies. t(15;17) for promyelocytic leukemia or M3. APTT and PT mixing studies. for microbiology i had one question about Erysipelothrix and another about Bacillus anthracis. i didnt get any blood gas and ANA questions at all.
Just took my ascp today for the 3rd time an I passed. I just want to thank you for the charts, they helped me so much I probably had over 40 questions that was all micro an it came right from them charts. An the rest was all bloodbank. I had maybe 2 urine and 5 dilutions and 1 or 2 pic for hematology. Was a really hard exam. I’m just so thankful for the charts they really saved my butt. An anyone else that failed it 2x don’t give up, I wanted to but I had people pushing me and alot of prayers to the man upstairs. Good luck to anyone going 2 sit for the exam.
Here are some of the exam contents that I can remember.. for BLOOD BANKING, most of them were about ABO discrepancies, DAT, HDN and they were all situational hehe. I had some questions about blood component storage and processing (take note of the storage temp and shelf life of each and how they are processed), transfusion rxns and donor deferral. Oh and I had several panels but they were all obvious (there was a pattern). For HEMATOLOGY, they gave me more or less 5 abnormal blood pictures and I had to identify which disease is specific to that corresponding blood picture (example: Burr cells – Uremia) I had one which goes “What red cell inclusion would appear on an infant’s blood smear after accidentally swallowing a mothball?” — I believe the answer is Heinz bodies. I had questions about sickle cell anemia, some leukemias, PT and APTT, mixing studies, and platelet aggregation. I was also asked to calculate for MCV and corrected white cell count. For CLINICAL CHEMISTRY, memorizing the reference values (refer to Polansky on this one) for each analyte especially bulirubin, BUN, glucose, and blood gases would do you great help. Most questions were of case study type. You must be familiar with the enzymes and hormones. Diseases/conditions I repeatedly encountered were Hyperthyroidism, lactic acidosis, respiratory/metabolic acidosis/alkalosis, SIADH, Addison’s and Cushing’s disease, diabetes mellitus and diabetes insipidus to name a few. I was asked to solve for osmolality, anion gap and creatinine clearance too. For MICROBIOLOGY, it is important to memorize or be familiar with the biochemical reactions (the charts in this site helped me a lot) for each bacteria especially Strep (CAMP, PYR, hemolysis, growth on 6.5% NaCl, bile esculin etc) and Enterobacteriaceae (IMVIC, TSIA etc). Also take note of the specific culture media for certain bacteria (ex: Fletcher medium – Leptospira). Some species that I could remember from my exam were Erysipelothrix rhusiopathiae and Bacillus anthracis. I also had questions about Fungi and their biochemical reactions and a few about viruses and parasites (autoinfection – Strongyloides). For URINALYSIS AND BODY FLUIDS, all that I can remember is that I was given a photo of a cast and crystal and I had to identify which types were shown and something about CSF, exudates and transudates. For IMMUNOLOGY/SEROLOGY, they were mostly about immunoglobulins and serial dilution. I had one question about PCR. I was asked to identify one ANA pattern too and the corresponding disease. And last but not the least, I had a few questions about TOXICOLOGY that I was completely clueless of.
My ASCP exam today was not easy…. but my preliminary result is PASS!!! Yay!!!! Thanks for the exam tips. It was helpful.
Questions on my exam were more on Mycology, Bacteriology, and Blood Bank!
Mycology: identification based on descriptions or microscopic view of the organism
Bacteriology: like you said, straight forward- biochem tests, growth on what media, so on… then identify which bacteria.
Blood bank: mostly ABO grouping discrepancies and Antibody screen probs- what u should do if u encounter this and that; and two questions about how many units do u need if you want this antigen-negative blood (given its frequencies in the population)
Hematology: cells in the smear ID; computations- diff count, cell counts; then which stain to use for this type of inclusion, hemoglobin suddenly decreases, platelet aggregation
Chemistry- i was asked to read and interpret HIV-1 immunoblot; questions about Hemolytic anemia (bili, urobili,haptogobin); i was asked about in what condition do you need to monitor Magnessiun, or when does K+ increase.
AUBF- nitrite question, when to suspect presence of contrast dye, reagent strip interferences
Passed my MLS exam yesterday. The first five questions gave me some trouble. Spend almost 30mins answering them. But after that I paced myself towards the rest of the questions. Heres some valuable information I want to share.
Know your GNR flowchart. I got at least 7 questions out of it. Include moraxella and acinetobacter to it because I neglected to include those to my chart.
Sharpen up on your antibody panel screen. I got at least 7 questions from it.
MYCOLOGY!! I got at least 9 questions including pictures. I think I bombed half of it.
I didn’t get lots of chemistry, I can guarantee you that. I braced myself for that subject and end up not getting many.
I got a few questions in hemo that included a couple coagulation questions about mixing studies and lab results for DIC TTP ITP.
Hey everyone took the test today and passssedddddd! I got a lot of questions That others got. Procanimide assay -Napa, picture of burr cells uremia, A lot of ABO discrepancies. That GPR chart is gold! I used this site, Harr, bottom line approach, cards, lab ce, and the SOP for ABO discrepancies from my job. I got only a few calculations, number of units needed and given frequencies, creat. Clearance. Umm Metabolite of cocaine-benzoglyce something or another. Bilirubin a lot of bilirubin. Was shown a picture of two slants grown in dark and pigment in light-M. Kanasii. Albumin fraction decreased, what else is decreased with it. Some other weird ones.

Organism that need fatty acids on medium to grow…
Lupus erythematose, what happen with complement decrease or increased, due to what….
Hello! I took my exam yesterday and luckily, I passed!!!!! Yes! Lots of questions on DAT and the frequency thing , you have to compute to get the total of units to crossmatch whatever. Harr and Ciulla are very useful. And of course, this site!! Thank you very much to the admin of this website. This is gold!
-No ANA questions for me.
-Majority (60%) of the questions are like if there is a blah blah blah, what to do next?
-picture of echinocyte
-picture of blastomyces dermatitidis
-Stomatocyte picture: what disease is related? LIVER DISEASE.
-no bloodbank panel but really lots of DAT. ABO descrepancies. And what are the remedies. (focus more on this)
-chemistry. how to measure hdl. I chose thin-layer but I really dont know. Ultracentrifugation was not on the choices.
I would like to say thank you for helping me pass the exam. i study 6 weeks for MLS. This website really helps A LOT!!! I have to say this… the questions and the study strategy REALLY HELPS. And for questions I was not sure I chose B. Therefore I chose many B’s..LOL..To be honest, I am a grade C student. Nobody would believe I passed the exam.

Not lots of DATS and ABO discrepancy thank god. No Leukemia and staining for me. Goodluck guys!!! Wish you all the best and happy new year!!
I just took my MLS exam and I passed! I stared at the screen for a while to make sure it really said “pass”.
I want to say thank you to all your wonderful note especially the coagulation note. Although I didn’t get any coagulation question, I’m happy that I finally get the pathway down.
In term of the exam, it was a hard exam for me. I spent all my 150 minutes. My first 40-50 questions were blood bank, micro, and immunology which are my 3 weakest subjects. I was extremely nervous. Break out:
– 5-6 questions about Abo discrepancy ( geeez)
– 2 antibody panels- find the antibody and choose which additional cells are used to rule in and out the antibody.
– 5-6 general questions about blood bank, technique, Dat
-2-3 about blood products
– I drew my gpc and gnb chart put before I answered any of my micro question. I got 4-5 question about gpc, gnb
– 1 question about micrococcus
– 2 question about plasmodium – which one is not show on the blood smear in troph
-4-5 mycology question( at this point, I was like:” why am I so not lucky”
– Ana positive shows what pattern
– picture and pick what kind of pattern: rim, speckle, ect
– chart of 1st and 2nd expose and tell them which a, b, c, d line are first and second response
– 1-2 hepatitis questions… But not in a traditional form of questions . One question was like : which blood product has a greatest risk transfer hep b( so I guess this is kinda a blood bank questions)
I got few easy ones: such as amalyse for mumps, tn/ tp
2-3 blirubin questions
They were hard too but I can not remember now.
Again, thank you for all wonderful
If you are scoring higher than 70 percent on the LabCe I think you should be fine. As for the questions I received, it was weird because it started off with QA questions and some instrumentation. I even remember them asking questions about how often we need to have CEUs. I had mostly Heme and Bloodbank. Heme was mostly hemagrams with abnormals asking for diagnosis or possible interference and some nrbc/wbc corrections, plt est and rbc inclusions, bloodbank I had tons of RH questions and basic antibody ID from warm and cold. Know your enzymes and effects. DAT IAT screening, donor qualifications. Chem I had some enzyme questions and calculations for GFR, AG, and creat clearance. Coag was basic intrinsic and extrinsic questions, know INR and the discrepancies with the times of pt and ptt. Micro, had about 10 to 15 questions. You should be just fine, stay calm and watch something funny right before to take the stress away prior. Eat some dark chocolate and some black coffee too!!! Thats what I did.
Basically passing the knowledge forward.
-I had a lot of mycology question (5) I believe, I’m pretty sure I got all of them wrong. They told me description and showed me a picture and I still got it wrong. I never really studied mycology and the ones I did never showed up.
-Had a picture of a pinworm and needed to know its real name and I didn’t get any more parasite questions after that.
-Chemistry: Effect of hemolysis on chemistry analytes, effect of IV line on chemistry analytes, Diabetes, non-ketoacidosis coma, enzymes for liver, enzymes to help ID muscle problems, cardiac enzymes, what creatinine clearance was (not the formula but what it actually tests–the physiology of it), a weird LDL + HDL methodology that came up twice (how can you separate them–I thought it was ultracentrifugation but that wasn’t even a choice, so if anyone knows please help enlighten me), given a bunch of analytes and their result (without the reference range) and was expected to know which one should be repeated (on it was BUN, osmo, Cl-, Na+, K+, and yeah… wasn’t sure of the answer on this one either). How to tell hepatic from an obstruction and what the test would show
-Urinalysis: what it means if someone has a normal serum glucose but a positive glucose urine test,picture of a cast with refractile circles and they asked you what other tests will help confirm it(?, choices were Sudan black, oil red O, picked oil Red O for some reason)–the almost exact picture can be found on labce
-Immunology: i had a question where it showed a picture of serum IFE and a gamma band and a light chain, and told you that the urine light chain had that light chain as well. Then asked what your next action could be: potential multiple myeloma, redo it again because ULC and S-IFE were not the same.
-Had some trouble shooting question and what would you do if the control you reconstituted were all whacky on all of your analyzers. Check the H2O you used, used new lots, or used fresh control.
-BB: panels are usually straightforward (I mean they do give some choices so that helps), but the tricky ones were the What would you do next if your forward had a positive Anti-B but your serum all came negative (reincubate at 37, report it out, redraw,) or for antibody screen if you wanted to rule out certain things what would you do (requires your knowledge about enzyme and its effect on on the different antigens)–what helped me to remember some were Duffy= gets Destroyed by enzyme
-Micro: the charts given on this site honestly are really helpful. they nitpick, I had one where I had to differentiate between Morganella and Providencia but it gives you a list of three different tests, and if you knew the answer it’s pretty simple because usually there’s one really wrong answer in all the other choices. Some mnemoics: MINOP )mirabilis Indole neg, o(something) positive—sorry my brain is getting fried at the moment, or K-PIN (klebsiella pneumoniae indole neg, E-COP (entero cloceae orthine positive), recommend making sure you memorize the chart on this site.
-what organisms would you look for in a patient with Cystic fibrosis
-Anaerobes Gram negative cocci that causes a disease involving the jaw
-know how to read a TSI slant and ID the organism from it
-know the differences between the Gram negative bacilli (like Enterobactericeae are all oxidase – (except plesimonas) vs the Oxidase+ GNB (like Aeromonas and the others), know the HACEK (the disease associated with them I got a question that told me symptoms and what it looked like and the biochemical and was expected to know it)
-Had two antibiotics question what other antibiotic would used to help ID a mecA gene (or something like that)–choices were vanco, ampicillin, penicillin, methicillin.
-What would you need to know in order to see the effect of a Therapeutic drug
-Had two questions where I was told whether serum Iron, ferritin, and TIBC was and had to ID the disease, had two questions on the same picture about what the disease could be and what I would expect the lab values to be
-There’s a labce question where it shows you four different pictures of an abnormal RBC morphology: know those (basically what target cells mean, sphereocytes, teardrops, schitocytes)
-What kind of drug would cause a hypochromic RBC–i answered malarial drug, but who knows..
-the virulence factor of N. gonorrheae,
-which mycobacterium is associated with contaminated H2o.
-glycerol effect on RBC (when will it expire–basically 10 years after the glycerol was added)
-summary: the purple yellow book is god, Do as much practice questions you can with Harr read over the explanation some things are a bit harder in the book though, but definitely read the explanation. DO labce I took 4 CAT and scored around the 50% mark (49-56%) and around a 5.5 hardness level. I did most of the Harr questions minus the end of chemistry and micro (ran out of time). Also look at the question wordsology and other people have put up, it helped me a lot in my preparations.
-The questions on the exam aren’t all that straightforward and that’s the one you know will probably be worth more points because it’s a higher level question.
THANK YOU Sohail, your website helped me a lot. I took the exam in Dec 2014 and failed, just took it a second time today and PASSED!! Hope that what i can share will help someone:
Lots of immunology and mycology.
Analyzer questions: flow cytometry how does it count the cells?
Identify a fungi by looking at picture of hyphae: I think it was Alternaria
Identification of anaerobic bacilli based on biochemical tests
2 questions requiring me to identify fungi genus based on description of fungal morphology. I remember “septate, hyaline, basidiomycota, arthroconidia” as keywords. Sorry can’t remember more keywords for this one.
Zygomycota: what are defining characteristics of this fungi
Purpose of check cells in blood banking, and what is a possible reason / lab error that would cause check cells to be negative?
Patient has a soft goiter and low TSH: what is the next lab test that should be done?
How long after whole blood donation should platelets be separated from RBCs?
How long after whole blood donation should plasma be separated from RBCs?
Coagulation mixing study: prolonged PT / PTT that corrects slightly with mixing study. Pt is not on anticoagulants. What could cause this?
Calculate creatinine clearance from pt lab values
Seemed to be lots of iron / transferrin questions. I realized during exam that I don’t understand purpose of transferrin very well.
There was a question on what CBC (iron changes? Transferrin?) a young healthy woman on hormonal birth control would have
CLL usually proliferation of T cells?
Several questions on Heinz bodies and what could cause it (oxidative damage)
Hi! I just wanted to thank you so much for your great work on this website. I just took the ASCP MLS exam this morning and I PASSED!! It was by far the most difficult exam I’ve ever taken, and I doubted every single answer and pretty much everything I knew about my life haha. Your website helped immensely, especially the microbiology section! I also used the Bottom Line Approach and the BOC book. I got a lot of pictures on my exam for some reason…picture of burr cells, what else would you expect to see in lab results? ANA pattern…HgbC, what would you do next. Picture of stomatocytes, related to what disorder. Super red slide, whats wrong with staining? Definitely understand sensitivity/specificity, I had like 4 questions about that. Also bilirubin, at least 5 questions on that too! No acid/base, no parasitology, a few simple mycology questions (hair perforation, cigar bodies), only one TSI. I had lots of Blood Bank discrepancies, Rh, baby DAT+. Every single questions makes you think over everything that you’ve learned, very few were straightforward. I swear there were some answer choices that could have both been correct. Choose the BEST answer. There were nearly always 2 choices that could be immediately ruled out. I reviewed half of my questions at the end, changed one answer, then decided to just submit. I still had 70 minutes leftover. My advice is to not let this test freak you out!! Take a deep breath, you will get through it!!
Some remembered Questions:
-Atleast 5 Mycology questions (wth), I was clueless on all of them
-No Parasitology for me
-3 Strep questions that can be easily answered by flow chart on this site (add bile solubility for Strep B-hemolytic to it)
-Staph questions – can be answered by flow chart on this site (add Mannitol to it)
-5 Enterobacteriace questions – Knowing IMVICs, TSIs, H2S producers, Lactose Fermenters and I used flow charts from yellow and purple book (Flow chart on this site is good, but I already was committed to bottom line approach)
-Nocardia – branching
-A/A+g what would you expect to see on HE agar – orange
-Oral Contraceptives – Increase in serum Fe
-ABGs!! – I had 3 acid/base disorders, one with partial compensation
-Calculate Osmolality (2 times), one of them didn’t have the answer (i tried both formulas), picked the closest one to the correct calculated osmolality
-Calculate Anion Gap
-Chylomicrons cause layer at top of tube
-Hashimoto’s – T4 decrease, TSH increase
-Turbid synovial fluid – (I put because of crystals)
-aHCG – Pacreatic CA or testicular? I picked Pacreatic
-4 Routine dipstick discrepancies
-Uroblilinogen false pos = Porphobilinogen
-Atleast 5 Jaundice questions – (know the urobilinogen reference range (along with the bilirubin reference ranges) something like 0.2 EU for urobilinogen) – Table in yellow and purple book made most easy
-caffeine benzoate in bilirubin assay – Accelerator
-Easy Panels (just identify, you have to use the Pearson Vue dry erase sheet to write out the antigens (not a big deal, but i guess if you are practicing, practice by writing out just the antigens on a sheet of paper.)
-ABO discrepancies (cold agglutinin, Roleux, no reaction on reverse type)
-Most severe HDN – ABO (BOC book)
-2 – RhIG calculation – Calculate vials, calculate feto-maternal hemorrage volume (same as BOC book/Media lab)
-QC for granulocytes (Yellow and purple book)
-Bombay Phenotype – hh
-Avoid allergic rxn something IgA – IgA/Washed RBCs
-2 questions – given absolute lymphocyte count, calculate CD56/calculate CD4 (I used 50% CD4, 25% CD8, 15% B, 15% NK – relative to calculate) – numbers came out where there was a clear cut answer
-Calculate LAP score
-Calculate Corrected WBC
-Myeloid Leukemia question that had indices, <10 blasts (thanks wordsology)
-Lots of blood smears, identify disease (look for the hallmark rbc/wbc deformity/inclusion – answers were mostly clear
-2 Histograms (identical to BOC book)
-Trepanomal highest specificity – FTS
-No ANAs!!…i thought this was going to be huge
-Flourometry – protect yourself from what – excited light or emitted light?
-PCR steps – the one that starts with Denature, Anneal
-Basophil – histamine/heparin
-ASCP CEUs required ?
Had some very specific molecular bio and other related questions that were total greek to me, meant to be answered wrong on the computer adaptive test i guess. I had one (impossible) question in which B and C were the exact same answer (I picked B). Most pics were very pixelated, they looked like resized avatars. Those ASCP questions need to be QC’d.
Anyway just so happy I passed, good luck to everyone!
My ASCP exam has a lot of challenging questions, but fortunately there are many similar questions to the ones that were posted on this website and shared by others. They ask me about specific gravity in urine testing, polycythemia vera, Burr cell, stomatocytes, CLIA requirement in competency, Cushing syndrome, defer donor in blood bank, lipemia interference, a few myco questions related to dimorphic, dermatophytes, blastoconidia, 2 ANA questions, CSF storage temp, diabetes, blood-gas, hemolytic anemia, DIC, Lupus, confirmed test method for HTLV, Pseudomas, Addision, how to detect early renal failure, a few UA case study questions, etc…
I just took my MLT exam tonight! I passed! WOOT WOOT! For my studying I used Clinical Laboratory Science Review – a bottom line approach, and I used the BOC book. I did subscribe to LabCE – I may did about 9 review exams. My scores for those were upper 60s and low 70s. I also used the high yield notes from here and I would totally recommend you know them inside and out! I didn’t get asked everything on them, but those micro flow charts are LIFE savers!
For me, the best resource was the bottom line approach. I am weary of just using LabCE or the BOC book because I feel like I’m just memorizing questions, and from the 9 review exams I took on LabCE, it does repeat questions. Sometimes it would ask me the same question it asked me at the beginning of the exam at the end of it…sooooo. Annnd there are several questions in the BOC book that either a repeat OR they provided the same answer they did for the previous question. For example, see question 215 and 216 on page 197. I really think the key is relearning the material or refreshing your memory on the material so that you can answer any question they throw at you, vs, well I memorized these questions and their answers. Now the BOC and LabCE are great tools to gauge what you know, and I do think that the more questions you see, the better off you are.
As for what I was asked – I was given a panel – these are easy points. Really, they give you the possible antibodies and all you have to do is focus on those. I was asked some very basic things like, B cells produce…. Thrombin time and why it would be increased or affected. I was asked about Beer’s law (yeah… I totally look over that… not). I was asked about absorbance, also I had two hematology histograms – see pages 204/205. It was like those but not those questions. I had several (maybe 4) TSI slants… sometimes I was given the picture, sometimes not. I was given two or three questions about agars and what grows on them, or if they were this color, what did that mean. I had several questions about which of the following would be VP positive, this positive and this positive and I’d have to pick the answer. I think I had three of those. I had a question about keratitis and the answer was Acanthamoeba…The Bottom Line book has a lot of quick and easy ways to remember things, like for keratitis and Acanthamobea… Kerry, aCanthamoeba causes Keratitis; associated with trauma to the eye. I was asked about Enterobius vermicularis… both were a pic to id it from (very similar to the ones in BOC but just had more of them in it), and then a question about what test you’d use to ID it but it still gave you the picture of Enterobius, so make sure you can ID them. I had some questions about glucose ox. converts glucose to gluconic acid …….. I picked and the answer is H2O2.. thank you bottom line! I had two questions that gave you a urinalysis and it would show you a pH and then say they found these crystals… what would you do. There is one like this in the BOC book. All you’re doing is looking at the pH and then thinking, is those crystals acidic or? What should you do? I had several questions about D/fetal/mom… those are to be expected. I had several questions about prehepatic. hepatic and post/obstructive… several, maybe 4 or 5? Sometimes they were easy and sometimes I had to really think about them. There is a wonderful chart in the Bottom line book that is a life saver if you ask me. Also, be prepared to see enzyme questions – liver and heart. I think I had two or three. I had several questions about discrepancies in ABO… like is it an auto, allo, subgroup, rouleaux…. I knew going in that BB was going to be my weakest. Uh, I did not have any questions regarding hep B, but I did have some on hep A. I had several questions on principles of antigen-antibody testing, like immunofixation, agglutination, etc. I had some questions on elutions, adsorption, neutralization so make sure you look over those and understand them.
I did not get any questions on crystals (none that required me to ID them), none on casts at all. I did get asked about the nephron and what is happening where, filtration rate, silly stuff. I did have some questions regarding rbcs and disorders or diseases so be ready for those.
I started the exam with what I thought were super easy questions. I breezed through the first 10-15… then I started to get questions where I had to really think. I started to get easy questions around mid 80s… and the last 10 were pieces of cake (well, I think I might have missed one of the last 10). I felt good in the first ten… about question 30-40 I was thinking I was not going to pass, and kept thinking, ‘ask me about those damn TSI slants! Where are my micro questions!? Urinalysis? Screw these immuno and bb questions”. When I got to question 90 and started seeing super easy ones I felt good. I did review my exam and changed maybe four or five questions, three I had misread and the others I just said what the hell.
My advice is to find a good review book or note cards and refresh your memory. I love the Bottom line because it gave me the cliff notes on everything! Plus it had neat ways of remember stuff, and also wonderful charts. Charts and graphs are a WONDERFUL tool and huge help. I highly recommend you know the high yield notes here. They are a life saver. Good luck to those of you reading this that still have to take the exam. LabCE is great to give you an idea of where you are at and to prepare you for getting a question about micro and then three about this subject… the BOC book is good, too, I just wouldn’t depend on it. I found several errors and I wasn’t really looking that hard and only looking at the MLT questions… who knows how many errors are in the book. So beware if you use it. Good luck! -and thank you to the guy who created this site and supplied us all with those notes!!
After failing the ASCP BOC exam twice I retook the exam and passed! I used the success book for urinalysis, hematology and immunology and serology. I used all the diagrams posted on wordsology and they were all very helpful. I also used labce in different variations using the suggested % (off this site) as the minimum requirement.
As we know the exam is a CAT so no exam is predictable as to what you should focus on. My 1st time taking exam it seemed like a horrible hematology exam, 2nd time it was filled with microbiology and 3rd and final time it was immunohematology based. Meaning that the questions were centered around that subject. So it can be a heme question but indirectly relating to immunohematology.
I had about 20 questions that were direct. The others not so much. Don’t try to guess what they’re asking for. Read the questions thoroughly and answer what they’re asking. That might seem obvious but sometimes seeing familiar terms in an answers throws you off and you might lean towards that answer.
Here’s so concepts that I realized was a major component of the questions.
Many GN Bacilli
Typical Mycology organisms
Renal pathology. (Success urinalysis section was the best study material)
~5 leukemia questions
Although rare I had about 6-8 panels that were no as direct as Labce
*Answer what they’re asking for. Don’t look for a “trick” don’t be paranoid.
Use anything possible to remember any and everything that you have to think twice about while studying.
PEE: IM (+) positive you’ll have to PEE
Are “IM” indole & methyl red positive. Along w/ studying chart off wordsology you will be able to id organisms w/ out a doubt.
Hopefully that was a little helpful to at least one person. Don’t give up!!!
I took the MLS-ASCP exam and passed. I thought that I would fail because I had many case studies (hematology, syphilis, chemistry) and blood bank questions on my first 50 questions. I reviewed my answers 4 times and I always pray every time I changed my answers. Before I finished the exam, I prayed so hard. Here are some of the questions I remembered that I immediately noted after the exam. I do not have all answers but the questions would be helpful in studying the ASCP exam:
1. What enzyme is increase in mumps?
b. Creatine Kinase

Good luck. Understand the Principle behind all the workings and you will have a good time.. If not sure – confuse.. flag em ..flagging gives you time later after you are done with the 100th item.. to go back to the flagged ones and analyze and be more confident of your choices. Tip: watch your time. Its critical that you are on top of the time element, especially if you are on the last 10 minutes.. and you have flagged a doz. and still stuck on flagged no.1.
Good luck and keep calm. All is good
The Sezary syndrome question, the whooping cough question, and the CMV question specifically. I HIGHLY RECOMMEND looking at ALL of the questions that are one this website. The one’s posted by Sohail are almost verbatim. This is what questions on your test will look like. Also, check out all of the questions posted by other commenters. I’m sorry that my brain dumped all of that information immediately after I saw the word “pass”, but many others did remember, and for that I am forever grateful.
I had no calculations, probably 5 parsasitology/mycology questions, and about an equal number of chem/hemo/micro/blood bank. Maybe 5 graphics to ID (blood smear interpretation, urine cast/crystals, microorganism ID. Most of the chemistry was interpreting lab results, and I had 3 panels that had indirect interpretation questions about them.
Hello! First of all, I would like to thank the author of this site. This is a must to read. Very helpful. I took the MLS(ASCP) exam today and I passed. Look at the questions Chellezy78 posted because I had most of those questions too. I wished I scanned all the questions here and it would have been easier for me. I had many Micro questions including about 5 myco (which I just guessed) and Blood Bank. Here are some things I remembered (without answers).

I will tell you that the most important thing is to try not to get overwhelmed. I let my nerves get the best of me the first two times that I took the exam. I was a lot more calm and relaxed this time around as far as the questions go here are a few things you should know about: Aquired B, what A1 lectin is, TSI slant reactions ( I had two questions about this), Entomoeba histolytica, normal volume of sperm, sickle cell electropheresis, sickle cell anemia photos, AFP, LDL, rbc indicies, corrected wbc count, anion gap…(I have had this all three times), Hep B stages of infection, passive immunity, aquired immunity, urine casts and where they are formed, CSF fluid, staph questions, strep questions, veionella- not sure if I spelled it correctly, mycobacterium, nocardia, I had a few BB questions on Bombay
I don’t remember most of the questions on my exam, but I will say this – I had 3 questions with ANA florescent slides, and none of my study sources were adequate for those. Know your pre/post hepatic dysfunctions, as I had about 3 or 4 of those. I also had 3 questions about ABO discrepancies, and a couple of DAT questions. Knowing your TSI reactions is also advised. I, like many others, was certain that I had failed the exam, but I didn’t. Hope this helps someone!
Question I remembered from my test : what nutrient is incorpriate in anaerobic ager to aid the growth of anaerobes I choses (glycerol and iron). A bacterial with A TSI A/A or acid over acid meaning the organisming is a fertermnt muciod pink on MacConkey nonmotile but indol positive I chose (klebsiella oxcitical). Omg this question right out of the BOC the question ask what are the characteristics of Microcouse is show they were suscepibal to (Furazolidone) to is question 125 from the BOC. The difference between Yersina entrocolitica and peptis and I chose ( motility). And question 235 from the BOC twisted around a blood culture grew a grew a bacterial that was thought to be a contaminate something of the sought and I chose (propionibactterium) and question from the BOC 330 twisted around.A mycobacterial that cause a water contaminat I chose (mycobacterium Gordonae) and it was right. Anther question BOC 313. The same way when stain acid fast bacilli with truant auramine-rhodamine stain potassium Permanganate is used to I chose ( quenching florencent background) and I was right is a quenching agent. Another similar question from the BOC to 304 to 307 why are first morning sputum needed for mycobacteria I chose (because if septum is held overnight the septum is invaded).
For chermistery I remember the following.
Instead of the whole liver panel they ask similar BOC 144, 145 ezyme do u see most in obstrctive jundiace or hepatoculluar obstruction between ALP and ALT and other ezymes I chose ( ALP) question. A caculation question of creatinine clearance question no the formula C=uv/p know that u always divide the total urine by 1440 and this is = to your volum. What you use to measure and instrument that absorb a flurecent light and transmit it at a large wave light I chose (. Flurometer) another question an instrument that. And an ezyme Usero measure choles something I chose (GGT) beause I thougt of alcohol when I saw the word coholes and didn’t see any thing about the lipid test so I went with that. BOC question 311 in the chermistery section the same question to detect barbiturate abuse when analyzing urine specimen I chose ( gas chromatography and mass spectrometry).
I passed! Questions I came across: PSA reference values and free/total ratio and what 7% free PSA means. HepB “anti-core window”. Free fatty acids to grow what fungus. Lots of blood bank ABO discrepancies. Pos DATs, mf reactions. LOTS of blood bank and quite a few urinalysis on the whole. Lewis antibodies in saliva of Group A Le(a-b+). HUS associated with E. coli. A few questions about Bilirubin and urobiliogen in urine/serum/feces. Direct/Indirect Bili. Know pre/post hepatic jaundice. A question about Erchlich’s test for urobilin/porpho test. Factor V Leiden and what it does. Coumarin therapy and how it affects. Theophylline therapy in babies and test for toxicity of what? HepB ANA homogenous/speckled/anti-smooth muscle/or anti-thyrotropine?…. What does plasmin do. Lots of urine strip test questions, like . CSF standing in room temp for 3 hours affects: immunoglob neutralization, glucose, etc. CSF should be stored for later testing how: -20C, -70C, RT, etc. Cushings shows: hyper/hypoglycemia or hypo/hyper calcium. Question about inappropriate ADH syndrome: decreased serum sodium, increased glucose, etc. Mg needs to be monitored in: severe vomitting, head injury, etc. bHCG level for positive control. Salmonella Paratyphi A. Sickle Cell test interference. Low serum erythropoein levels in what disease. Normocytic/Normochromic severe anemia with 0.1% retics; Fanconi’s anemia? One calculation: corrected WBC count. Pheochromocytoma. Catecholamines in urine. What does 5HIAA in urine mean. Given electrolyte panel and blood gases, what to measure: ethyl glycol, lead, salicylate, etc. Given picture of Auer Rods, confimatory testing (Phili Chromosome?) Absolute/Relative lymphocytosis/lymphopenia. A few questions (at least 3) about precision/sensitivity/specificity with true positives, false pos, true negs and false negs. My question was TP/(TP+FN)=? What are blastoconidia. Stain for cryptosporidium. Mycoplasma and arylsulfatase testing. Seminal fluid volume, motility, abnormal %. Distinguishing characteristic of micrococcus (furazolidone resistant). Non-fluorescing bacteria like Pseudomonas. I hope this helps!! Lot’s of random detailed questions…. These are probably the harder questions since I can remember them. Ex. of an “easy” question I got would be: shape of tyrosine crystals in urine, but not too many of those gimmes. It was hard, not gonna lie.
I failed on my first attempt -MLS(ASCP) exam. I got 381. I needed 400 to pass. I was disappointed because I thought I did good answering most of the questions. I had 4 antibodies panels in BB. I can not remember all the questions but here are a few of them: Tumor marker to monitor breast cancer(CA-15-3). Test for inflammation(CRP). Sweat test ..which of the following is used to clean the skin…70% alcohol, Water, Betadine. Respiratory Alkalosis. Anti Immune disease with an elevated ALP. Clinitest result turns quickly from blue to orange and back to blue….is this test pos or neg? 10ml of chemical sol spilled in the lab…pull the fire alarm, clean the spill, ask everybody to evacuate the lab? test to identify hairy cell? class of leukemia FM1 and FM3. what is a look back test procedure in QC that is more than one times out for a particular test.
I passed my MLS on my first time. I didn’t do LabCE because I was too late when I found it out and beside I already bought a few study guides, but the one that I most spend my time with was the Harr book, ASCP BOC book, and a botton line approach plus my class notes; it can be overwhelming, but I advice to focus brush through the small details and focus on the main stuffs, like really understand prehepatic/posthepatic jaudice in relation with bilirubin and urobilinogen, Hepatitis antigen and antibodies (their window), abnormal protein electrophoresis (each disease it entails), and RBC’s inclusions (howell bodies, peppenheimer, heinz body be able to ID them!). I got few questions on mycology and maybe 0-one on parasite, focus on chemistry, BB, hem, and micro more. BB more on ABO Rh, DAT, IS descrepancies. If you know the basic stuffs on each, you should be fine. Good Luck to future tester!!
I just took my ASCP exam this weekend and passed, and I just want to say thank you for this site. The notes really helped me to recall information. I do want to say that my test included all of the subjects with most of them being blood bank. I actually had more questions than I expected of virology, immunology, QC, instrumentation, and mycology. I would suggest that people planning to take this exam to not brush over those subjects because I probably had 10 questions from these areas. I also had questions about bilirubin, odd organisms in microbiology, pictures of immunodiffusion and what they meant, factor deficiencies/inhibitors, TSI slants, antibodies to various viruses and what they meant, QC question on machine with “no endpoint”, what cocaine is metabolized to, a few questions on liver and cardiac markers, a few questions on endocrine system/steroid hormones, pheochromocytoma, lots of questions on HDN, antibody panels, antibody screens, discrepancies in blood bank, etc. I was very nervous during the test and it was very difficult. I am just so happy to say I passed! Thanks for all your help!
I took my ASCP exam and passed! Thanks Sohail for your website and it’s great for future MLSs to support each other to succeed. My resources (in order of importance) were the Harr book, the review cards, and the LabCe. I must admit I didn’t use the LabCe too much, just a couple of times did the computer adaptive mode, and practiced some questions in my weaker area. I was getting 50% on the computer adaptive mode, so it was a bit discouraging. The exam today had ABO discrepancies, micro (mostly on GPRs & GNRs, mycobacteria), lots of UA/reagent strip case studies (unexpected). It is important to know the main reactions of certain organisms and what they need. ex) malassezia furfur requires olive oil, which org has gliding motility..etc. As long as you’re confident, you may do well, and the review at the end helped me go back and make sure I answered to the best to my ability. I did just graduate last month after a semester-long internship, so that helped.
Here are some questions that came out and remembered. I wont do into detail because I forgot some choices with the question.
– if there is a rouleaux formation on the blood what will you do? (bunch of choices-forgot what the choices was) = saline replacement
– Slide of a smear = it was metamyelocyte
– Slife of immature celles (mye,meta,looks like blasts etc) what test to confirm? a. ph chromosome b. sudan c. oil red d. pas = Not sure with the answer but I choose “a”
– xmatch: DCe/DCe recepient, xmatched with 4 donors, DCE/DCE, dCe/DCE, etc.- anyway there were 4 donors and 2 of them incompatible then asked what Ab is present: Choices: a, C and D b. E and D c. anti c d. anti E ( sorry not perfectly sure what the right choices are but you get the point)
– Some urine strip questions (yup I think I had 4 of them!) = patient came from radiology with urine sg 1.054 done on refractometer and 1.028 on strip what are you going to do or something : a. strip deterioted b. result matched c. calibrate the refractometer d. correlate result with ph
– rgt strip protein negative but SSA 2+ what the cause? cant remember the exact choices the only one I remembered for this is , false neg due to amorphour urates or other protien present,
– I had a pix of electropheresis of SLE: a rim b. centromere c. nucleolar d. diffuse – I think I answered centromere here not sure
– What rgt deteriotes faster when in use a. MN b. Le c. Jka d. Fya
– Jka ruled out but not anti c and anti Kell. tested for Ag Anti Kell = Anti c +? a. comfirmed c but cannot rule out k b. cannot rule out c. confirmed K but not c d. confirmed c but kell can neither be ruledout or confirmed
– nephrotic dse what is seen? a alpha 2 b. albumin, c. gamma d. alpha 1 (not sure with the exact wording on this but you get the point)
Ok that are the only things that I can remember for now. For micro I have maybe 5 of them but honestly I cannot remember them. They are so hard to remember. I had only 1 mycology, no virolgy, no lab operations and no parasitology. I think I had micro, hemo, blood bank and chem equally and yes I had lots of microscopy. And of course as all previous taker here pls study all the desease that correlates with lab results. Like the bilirubins, ABO discrepancies, Coagulation resutls. For biochemical reaction I only had one and it was about a enterobacteriacae. I think my answer was enterbacter. ANyway sorry if this is too long for you guys but I will help other future examinee as best as I can. So hope this helped. Good luck!
Thanks, Sohail! 🙂 Here are the questions I can remember that were just out-of-the-blue and were not in any patterns mentioned in my “PS” below. Hope it helps. God bless!
>For ISE measurements, a ____ membrane is used to selectively bind potassium.
> RIST test detects what?
> Using compensated polarized light, what is positive (blue) for birefringence?
Uric Acid or Calcium pyrophosphate?
> Lab Management questions regarding turn around time and MSDS(?)
> In an exchange transfusion for cases of Rh HDN, whose blood type (mother or baby or father or just Group O negative red cells) do you transfuse?
> Safety precautions you have to take when a lab personnel is electrocuted. What to do when he/she is “stuck” to the electric source itself?
PS- Here are the ‘patterned questions’
(questions that were given in a row referring to the same topic)
-I had ALOT of antibody panels
-Microbiology Enterobacteriaceae identification pictures
(the micro charts on this site were VERY helpful)
-Interpretation of Blood Gas results (NOT “metabolic acidosis/alkalosis”, but what caused it- vomiting, hypokalemia, renal impairment, etc)
Passed. Some of what I got: Antibody least likely to display dosage, Bilirubins in hemolytic anemia, Tumor marker question, calculate RBC count from hemocytomer with given dilution and squares counted, slide with picture of stomatocytes what disease state, diabetes given fasting 128 Glucose tolerance >200, badly stained slide with crenated rbcs what caused, formula given specificity or sensitivity, fluorescence protect yourself from what, slide with blast with auer rods stains most beneficial for diagnosis, slide with RBC agglutination saw twice one time incompatible transfusion other cold agglutinin, RBC H/H given rule of 3 do not correlate lipemia, bile stained “mammillated” (yes BS wording) Ascaris lucky guess, 1+ leukocyte esterase no WBC’s seen why, list of Coag results post surgery indicative of what, an acute hep question (again BS wording) made more difficult than should of been think I got right, unit released brought back within 30 min but “entered” (damnit into what) on floor discard, picture of TSI tube what org. My take I feel like I was tested on reading comprehension more than my ability to not kill someone, would not be surprised if I got exactly 400. I think I changed a couple that I was on the fence on, problem is I think they were right initially. About 4 questions were related in that I had no idea but after seeing the other question I could deduce the answer to the initial question. Had no full Ab panels but some weird mini panels, some discrepancies (not exactly easy), no cardiac enzymes, no thyroids, maybe one blood gas, one or two fungals (probably missed maybe got lucky). Anywho, study hard and you should do fine. Thanks and good luck.
I used your website over the past two months to prepare for the ASCP MLS exam. I took my exam this morning and passed! I just wanted to say thanks to you for putting this site together. It allowed me to organize a study plan that worked.
To those who are preparing to take the exam, study his micro charts! They include everything you need to know to make it through the micro questions on the exam.
Questions I saw on the exam today (July 2013): abnormal PT and APTT results, ANA patterns, RIST vs. RAST, lots and lots of micro biochemical reactions, several antibody panels, abnormal cells on peripheral slides and hematology values, many questions over liver enzymes and bilirubin metabolism, a few over the thalassemias, a couple of parasitology and mycology questions, one question over education objectives, one protein electrophoresis, corrected WBC calculation (nRBC), two dilution calculations
Materials I used to study:
LabCE: I was scoring between 51-55% on computer adaptive setting, 78-80% on the MT 100 question practice exam, and 75-80% on subject tests
Clinical Lab Science Review: A Bottom Line Approach by Patsy Jarreau
YouTube videos ( especially over the thalassemias and bilirubin metabolism and associated diseases)
I used this website to organize my study plan. I studied for a little less than two months for a few hours per day. The week before the test, I reviewed the main four subjects and studied several hours per day.
Hope this helps! Good luck.
Hi I took the test today and passed. I have to say it was very hard and like others have mentioned I was pretty sure I had failed around question 50. MY questions certainly didn’t get any easier at the end! There were about 20 I was certain of the answers, kind of straight fact questions. MANY seemed to be the same as John (from March 2013) mentioned above. READ them very very carefully and make sure you know exactly what they are asking. AND some were so vague! I got the one about the unit being “entered” on the floor. Literally the question was ” A unit of blood was issued at 11:15a. After being entered on the floor it was returned at 11:40a. What do you do with the unit?” I am with John-entered into WHAT-the med record? the unit entered?–which now seems like the most logical-but many questions were like that. Minimal information, and what seems to be the correct answer not being there. My favorite (!) was this one: “A med tech sets up QC on new TSI slants using E.coli and P.mirabilis. The results were as follows: E.coli: alkaline slant, acid butt, H2S. P.mirabilis: alkaline slant, acid butt. The answers were: 1. accept QC; 2. Run 2 H2S negative organisms; 3. Run ATCC strain of E. coli, 4. Reincubate. WELL I am a micro tech and first of all most ecoli is not H2S positive, and P. mirablis is H2S positive. And why wouldn’t you have run an ATCC strain in the first place? So the results are screwy to begin with. But out of those choices–What the ????. I picked 2, but who knows!? Looking back I think if you REALLY learn what is on the Polansky cards, and the Clinical Lab Science Review: A Bottom Line Approach by Patsy Jarreau, you will be good. I CANNOT emphasis enough learning bilirubin stuff–urine and blood results for prehepatic, hepatic, post hepatic biliribin and urobilinogen -lots of questions–know the references ranges for total, direct, indirect, conjugated, unconjugated, urine, and blood, know what diseases that elevated values match up to. Maybe because micro is easier for me there seemed to be less of that on there. It seemed like mostly blood banking, chemistry, and hematology. Weird hematology pictures-got the same pictures twice with 2 completely different sets of questions. Know the stains! The only math I had was indices-not just knowing how to calculate them, but using the calculations to diagnose, and a manual RBC count. A few small cell panels. I was really surprised by how minimal and vague some of the questions were. “A known alcoholic comes to the ER. He has cardiac symptoms. His glucose is 180. What test do you run next?” choices; HgBA1C, magnesium, alcohol, glucose tolerance. OMG!! Most of the urine questions were about discrepant dipstick results. A couple mycobacterium questions. I did see the “pass” on the screen but I was so unnerved by the test and shaking, I had to sit in my car for awhile before leaving 🙂.
I studied on and off for a few months before taking this exam, which I highly DON’T recommend. Bob Harr was my program director, so I had his book memorized because he and all of my other teachers used questions from his book for our exams. I also used the review book by Patsy Jarrean, along with this site and LABCE. I was very fortunate with my clinical experience and was able to use that knowledge for most of the questions. When I took the LABCE exams, I was scoring in the upper 400’s and lower 500’s. Questions on LABCE repeated themselves semi-often and some of the explanations for correct choices were unhelpful. For example, if I got a question wrong it would say “Answer: 41565 was the correct answer. Description: 41565 is the correct answer.” If you can get a classmate to buy a subscription and share their password with everyone else, I would do that.
The exam wasn’t too bad. For every question I had no idea what to pick, I guessed B (like Harr said). Take your time, I had an hour left when I finished. I went back through and tried to memorize as many questions as I could, mainly for this site. I didn’t change a single answer, it is best not to second guess yourself. You can take a calculator in with you, but you leave everything, even watches and pens, behind. They give you a marker and a dry-erase board so you can write anything down. I immediately wrote all the micro charts from this site, along with a few calculations. You can take a break any time, but time still ticks down. I took a 15 minute break just to clear my head and walk around. They also provide sound-proof headphones, if you would like to use them.
My advice, schedule your exam early because dates can fill up fast. I tried to sign up for a day during the first week of the month, but there was only 1 slot available the whole month. Pearson doesn’t just offer medical related exams, they do stuff for all trades. Also, make sure you send your transcripts in advance to ASCP or they will not send you the certificate. It takes about 3-5 weeks to send your certificate if you have everything submitted.
Because I don’t want to give incorrect answers and steer you wrong, I tried to say most of the choices that I can remember. I scored in the upper 400’s on the ASCP, so I’m no genius. Also, double check all my answers before studying. Answers with a question mark are ones that I am not 100% sure are correct. Also note that if I only list 3 of 4 answers, that’s because I cannot recall the 4th choice. There may be another “better” answer that I cannot remember.
The majority of questions on your exam will probably be on your weakest areas, as confirmed by me and a few classmates. I studied 3/4 of the main areas hard, but got screwed by my weakest.
So…here’s the questions I recall from my exam:
1) Mother Le(a-b-), what would cause this? – mother loses lewis antigens while pregnant
2) Mom is A+ baby is B+ elution shows: Acell 2+, Bcell 2+, SC1 0, SC2 0, SC3 0 – what antibody is present?
3) Given a panel, all but one cell reacted at AHG. Asked which cell should be used to rule out Anti-C and gave 4 more possible cells as choices.
5) One ABO discrepancy, asked the cause. Reactions: Anti A 4+, Anti B 0, A cells 0, B cells 0
6) Number of rhogam vials to give mother if fetal blood is 62.
7) Cause of weak D – missing epitope….?
8-12) I had 5 panels. Make sure you know how enzymes affect panels. Half of my panels had an enzyme column.
13) An O positive Patient has a known anti-K. Which of the following is true?
A) 93% of O blood will be compatable
B) 7% of O blood will be compatable
C) 93% of A blood will be compatable
D) 3% of A blood will be compatable
1) LDL calculation – straight up, no gimmicks
2) HDL was 34, Trig was 400, and cholesterol was 235. LDL was directly tested and was 169. (P.S. if you know the correct answer to this, please tell me. I know that you cannot calculate the LDL if the Trig is above 400, but I keep second guessing myself)
A) Report out calculated LDL
B) Retest Triglycerides and recalculate LDL
C) Retest cholesterol and recalculate LDL
D) Recollect while fasting
3) Gave 4 anion gap equations and asked which one would give an error – one had a negative value
4) Asked the definition of an automated delta check
5) Analyzer is set to delta check sodium at +/-7. Of these results, which would delta check? (and yes, there were 2 that would “technically” delta check”)
Day 1: 137
Day 2: 141
Day 4: 132
Day 5: 137
Day 7: 136
Day 8: 142
Day 10: 134
A) Day 1
B) Day 4
C) Day 8
D) Day 10
6)Patient with HA1C of 5%, glucose is 150. – Patient was following diet for beginning of 3 months and stopped.
7&8)Know your chemistry enzymes from the chart on this site. It is EXTREMELY helpful.
Which of the following is increased in skeletal muscle disorder

6) Low WBC, low RBC, low Platelet count – asked which lab test would be useful to add on for anemia diagnosis
7) Blood was opened for a long period of time, what would happen to pH, pCO2 and pO2
8) Blood with strong cold antibody will – agglutination on smear
9) Picture of agglutination, asked increase in what causes it?
