MLS ASCP ACTUAL EXAM RECALL QUESTIONS 2023 WITH
ONE HUNDRED PERCENT VERIFIED ANSWERS
Exam
Procainamide - answerNAPA
loose clusters of small spherical microconidia, positive urease - answerTrichophyton
mentagrophytes
BHCG tumor marker - answerchorocarcinoma
5HIAA - answercarcinoid tumors
Proteus vulgaris vs P. mirabilis indole test - answerP. vulgaris is indole pos. P. mirabilis
is indole neg
Hydatid cyst fluid - answerused to neutralize Anti-P1 antibody
Antacid overdose - answerCheck pH
Prolonged PT, PTT, and thrombin after collecting from catheter - answerheparin
contamination
mixing study that was performed with a prolonged PTT that couldn't be corrected -
answerDRVVT (Dilute Russell Viper Venom Test)
two pt's ran in duplicate (PT and PTT). The PTT seemed to always be prolonged but PT
looked ok - answercheck the CaCl/phospholipid reagent delivery
Patient is on coumadin therapy, what will be affected - answerDecreased protein C
Lot's of stomatocytes - answerLiver disease
Burr cells - answerUremia
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 - answeranti-lysing target cells are what increased the white
count? Erythrocytes containing hemoglobin C do not lyse normally (sickle cell diseases)
, A sodium citrate tube was drawn for a HCT on a pt but the hematocrit was abnormal -
answerrecollect with decreased anticoagulant. high hct (>55%) causes low plasma so
you need less anticoagulant
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 - answercheck for lipemia
(elevates HGB)
PBS with an elevated reticulocyte count and howell jolly bodies in the RBC's -
answerPrussian blue for howell jolly bodies made of iron. Prussian blue stain, which is
not taken up by reticulocytes, is helpful in differentiating the two.
what is composed of DNA? - answerhowell jolly bodies
what falsely increases ESR - answervibration, tilting of tube, higher temps, >1 hr test
time, improper mixing of blood, improper dilution
factors decreasing ESR - answerPolycythemia, Microcytosis (Hb C), Sickle cells,
spherocytes, Anti-inflammatory medications, Hypogammaglobulinemia,
Hypofibrinogenemia (DIC), High WBC count, Hyperviscosity
Factors increasing ESR - answerAnemia, Macrocytosis, Female gender, Age >50 years,
Obesity, Pregnancy, Hypercholesterolemia, cancer, multiple myeloma, rouleaux,
infections, inflammation
what falsely decreases ESR - answerlow blood/ room temps, air bubbles, tests <1 hr,
improper mixing of blood, improper dilution
lactic acid collection - answerseparate from serum and put on ice
coefficient of variation - answer(standard deviation/ mean) X 100
Carbon dioxide electrode measures what - answerUsed to measure free carbon dioxide
ions by detecting pH. The change in pH is measured by an internal pH sensor, which is
proportional to the carbon dioxide level.
patient that had a random glucose >200 and an FPG >126. What do you do next? -
answerdiagnosis with diabetes mellitus.
(need secondary confirmation from 4 criteria. FRG >126, Random glucose >200, ogtt
>200, or Hb A1c >6.5)
Man tested positive for syphilis 2 years ago but may have again, how would you test
him? - answerRPR
Person tested positive for HIV-1 and HIV-2 but western blot was indeterminate. What do
you do? - answerrepeat western blot in a month.
