MLS ASCP EXAM RECALL QUESTIONS
AND ANSWERS 2026 VERIFIED.
Procainamide - ANS NAPA
loose clusters of small spherical microconidia, positive urease - ANS Trichophyton
mentagrophytes
BHCG tumor marker - ANS chorocarcinoma
5HIAA - ANS carcinoid tumors
Proteus vulgaris vs P. mirabilis indole test - ANS P. vulgaris is indole pos. P. mirabilis is indole
neg
Hydatid cyst fluid - ANS used to neutralize Anti-P1 antibody
Antacid overdose - ANS Check pH
Prolonged PT, PTT, and thrombin after collecting from catheter - ANS heparin contamination
mixing study that was performed with a prolonged PTT that couldn't be corrected -
ANS 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
- ANS check the CaCl/phospholipid reagent delivery
Patient is on coumadin therapy, what will be affected - ANS Decreased protein C
Lot's of stomatocytes - ANS Liver disease
Burr cells - ANS 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 -
ANS anti-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 -
ANS recollect 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 - ANS check for lipemia (elevates HGB)
PBS with an elevated reticulocyte count and howell jolly bodies in the RBC's - ANS Prussian
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? - ANS howell jolly bodies
what falsely increases ESR - ANS vibration, tilting of tube, higher temps, >1 hr test time,
improper mixing of blood, improper dilution
