Fun Quiz: Test Your Blood Bank and Immunohematology Knowledge

#1. Upon inspection, a unit of platelets is noted to have visible clots, but otherwise appears normal. The tech should

Filter to remove clots

Centrifuge to express off the clots

Issue without concern

Quarantine for gram stain and culture

#2. The following are tests routinely performed on donor blood except

Fibrinogen

Antibody screens

Serologic tests

ABO

Rh

#3. Cryoprecipitate AHF, if maintained in the frozen state at -18C or below, has a shelf life of

12 months

6 months

42 days

36 months

#4. Most frequent transfusion-associated disease complication of blood transfusion is

Hepatitis

HIV

Syphilis

Cytomegalovirus (CMV)

#5. IgG autoantibody associated with Paroxysmal Cold Hemoglobinuria

Anti- Lewis

Anti D

Anti-c

Anti-P

Anti-I

#6. What is the ABO type of check cells

A

AB

O

B

#7. Genetically hh or lack of H substance on the surfaces of red cells

AO phenotype

Null phenotype

Bombay phenotype

BO phenotype

OO phenotype

#8. Why must RhIg be considered when transfusing platelets to a female of childbearing age?

Trace amounts of anti-D from the donor might react with D antigen of the recipient causing a transfusion reaction

Platelets carry the D antigen

Red cells that remain in the unit may carry the D-antigen

RhIg has no effect the patient when transfusing platelets

Reduce the risk of GVHD

#9. If a person has only H blood group substance, what antigens will be found on his red cells

O antigens

D antigens

H antigens only

A & B antigens

A, B and H antigens

#10. The Kell antigen is

Destroyed by enzymes

Strongly immunogenic

Absent from the red cells of neonates

Has a frequency of 50% in the random population
