MLS ASCP EXAM RECALL EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+ 2025 – 2026
Proteus vulgaris vs P. mirabilis indole test - ANSWERS-P.
vulgaris is indole pos. P. mirabilis is indole neg
Factors increasing ESR - ANSWERS-Anemia, Macrocytosis,
Female gender, Age >50 years, Obesity, Pregnancy,
Hypercholesterolemia, cancer, multiple myeloma, rouleaux,
infections, inflammation
what falsely decreases ESR - ANSWERS-low blood/ room
temps, air bubbles, tests <1 hr, improper mixing of blood,
improper dilution
lactic acid collection - ANSWERS-separate from serum and
put on ice
,coefficient of variation - ANSWERS-(standard deviation/
mean) X 100
Carbon dioxide electrode measures what - ANSWERS-Used
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? - ANSWERS-diagnosis with diabetes
mellitus.
(need secondary confirmation from 4 criteria. FRG >126,
Random glucose >200, ogtt >200, or Hb A1c >6.5)
Hydatid cyst fluid - ANSWERS-used to neutralize Anti-P1
antibody
Antacid overdose - ANSWERS-Check pH
Prolonged PT, PTT, and thrombin after collecting from
catheter - ANSWERS-heparin contamination
, mixing study that was performed with a prolonged PTT that
couldn't be corrected - ANSWERS-DRVVT (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 - ANSWERS-check the
CaCl/phospholipid reagent delivery
Patient is on coumadin therapy, what will be affected -
ANSWERS-Decreased protein C
Lot's of stomatocytes - ANSWERS-Liver disease
Burr cells - ANSWERS-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 - ANSWERS-anti-lysing target cells are what
increased the white count? Erythrocytes containing
hemoglobin C do not lyse normally (sickle cell diseases)
