MEDICAL LABORATORY (Blood Banking)
ACCURATE AND FREQUENTLY TESTED
QUESTIONS TO PREP FOR YOUR EXAM.
RT, a 37-year-old woman, is a first-time donor at your blood center. She is
a healthy donor, has an unremarkable medical history, and is not taking
any medications. Initial ABO phenotyping results indicate an ABO
discrepancy.
ABO Testing Results:
Donor Red Cells with:
Anti-A: 0
Anti-B: 4+
Donor Serum with Reagent Red Cells: A1: 3+
B: 1+
1. Is the discrepancy associated with the red cell testing or the serum
testing? State the reasons for this selection.
2. What are the potential causes of an ABO discrepancy?
3. How would you resolve this discrepancy?
Is it possible to prepare cryoprecipitated antihemophilic factor (AHF) and
fresh-frozen plasma (FFP) from the same blood unit? Explain your answer
True or False: The serum of some group A individuals may agglutinate
group A1 cells.
,True ??
True or False: For infants born to Rh negative females, a test for weak D is
optional when initial D typing shows the newborn to be Rh negative.
False
Which of the following contains all the possible phenotypes that could be
the result of parents who are type O and type A:
A. Type A or type O only
B. Type A only
C. Type O only
D. All possible blood types
Type A or type O only
Which of the following is not a major Rh antigen:
A. D
B. d
C. C
D. c
anti-d
The proper storage requirements for granulocyte concentrates is:
A. 1 - 6 degrees Celsius, < 12 hours
,B. - 20 degrees Celsius, 48 hours
C. 1 - 6 degrees Celsius, < 24 hours
D. 20 - 24 degrees Celsius, < 24 hours
20 - 24 degrees Celsius, < 24 hours

group O patient:
A. Group A
B. Group B
C. Group AB
D. None of the above
none of the above
A patient with Multiple Myeloma has the following reactions in the ABO
typing:
Anti-A= w+
Anti-B = w+
Anti-A,B = w+
Auto control = w+
, A1 Cells = 4+
B cells = 4+
What is probably causing these results?
A. Rouleaux
B. Subgroup of A
C. Patient has hypogammaglobulinemia
D. Patient has selective IgA deficiency
rouleaux
If an Rh negative patient is administered a unit of R1R1 packed red cells,
which one of the following antibodies would be most likely to develop:
A. Anti-C
B. Anti-E
C. Anti-e
D. Anti-D
anti-E
Why would a unit of group O blood never be administered to a Bombay
patient:
A. Anti-A in donor
