ASCP BOC 2026 EXAMINERS SET QUESTIONS AND
ANSWERS SURE A+
✔✔In flow cytometric analysis, low angle or forward scatter of a laser light beam
provides information that pertain to a cell's: - ✔✔volume
✔✔For safe operation of a centrifuge: - ✔✔ensure proper balance is maintained
✔✔Which of the following activities is associated with C3b? - ✔✔opsonization
✔✔Which of the following specimen requests is acceptable - ✔✔urine for culture of
acid-fast bacilli
✔✔In polycythemia vera, the platelet count is - ✔✔elvated
✔✔A mass spectrometer detects which property of ionized molecules - ✔✔mass to
charge ration
✔✔Severe intravascular hemolysis is most likely caused by antibodies of which blood
group system?
a) ABO
b) Rh
c) Kell
, d) Duffy - ✔✔ABO
✔✔urine specific gravity is an index of the ability of the kidney to: - ✔✔concentrate the
urine
✔✔When using the turbidity (solubility) method for detecting the presence of
hemoglobin S, an incorrect interpretation may be made when there is a(n): -
✔✔increased total serum protein
✔✔When cleaning up a small (5 mL) blood spill on the counter-top, the first step after
donning appropriate personal protective equipment is to: - ✔✔absorb the spill with
disposable absorbent material
✔✔A serum sample was assayed for bilirubin at 10 AM, and the result was 12 mg/dL
(205.6 µmol/L). The same sample was retested at 3 PM. The result now is 8 mg/dL
(136.0 µmol/L). The most likely explanation for this discrepancy is - ✔✔the sample was
exposed to light
✔✔After receiving a 24-hour urine for quantitative total protein analysis, the technician
must first: - ✔✔measure the total volume
✔✔The causative agent of cysticercosis is: - ✔✔Taenia solium
✔✔which of the following is a characteristic of polyagglutinable red cells - ✔✔are
agglutinated by most adult sera
✔✔The purpose of a low-dose irradiation of blood components is to:
a) prevent posttransfusion purpura
b) prevent GVHD
c) sterilize components
d) prevent noncardiogenic pulmonary edema - ✔✔prevent graft-vs-host GVHD
✔✔the genus of virus associated with anogenital wart, cervical dysplasia and neoplasia
is: - ✔✔papillomavirus
✔✔n emphysema patient suffering from fluid accumulation in the alveolar spaces is
likely to be in what metabolic state? - ✔✔respiratory acidosis
✔✔An automated CK assay gives a reading that is above the limits of linearity. A
dilution of the serum sample is made by adding 1 mL of serum to 9 mL of water. The
instrument now reads 350 U/L. the correct report on the undiluted serum should be: -
✔✔3500 U/L
