1. How would Ulex europaeus react with O, A, A2, B, A2B, O>A2>B>A2B>A1>A1B
A1B RBCs?
2. How could you distinguish serologically A1, A2 and A3 Dolichos biflorus can will
react with A1 and not A2.
A3 yields mixed field re-
actions with anti-A and
anti-A,B
3. What is the correct order of type of RBCs to transfuse A, B, O; the residual anti-B
in an AB patient when AB RBCs are not available? Why? in A RBCs is less immuno-
genic than the residual
anti-A in B RBCs
4. What type of RBCs would you transfuse to a patient RBCs transfused must lack
with anti-G the D and C antigens
5. Can you detect a weak D using Gel Technology? No, because there is no
washing phase
6. Can an Rh positive father and Rh positive mother yield Yes, if both parents are
an Rh negative child heterozygous for the D
gene. Inheritance is auto-
somal recessive
7. What type of RBCs in regards to Rh phenotype would RBCs should be negative
you transfuse in a patient with anti-f for the c and e antigens
8. How could you solve an ABO discrepancy where Treat A1 cells with ficin to
Anti-M was causing aberrant results in reverse group- denature the M antigen,
ing when the forward type is consistent with A blood repeat reverse grouping
group and reverse as O? with ficin-treated A1 cells.

9. Why do you see an anti-N like specificity in dialysis Formaldehyde induced
patients? antibody to 'N' due to
formaldehyde used in
dialysis procedures.
10. A patient types as follows: anti-A=4+, Anti-B=1+, A1 Anti-B was adsorbed out
Cells=2+, B cells=4+. The ABO discrepancy led to suspi- with RESt.
cion of a possible cold autoantibody based on patient
histopry and diagnosis. RESt was used in an attept
to adsorb the autoantobidy. The type was repeated
with adsorbed plasma Anit-A=4+, Anti-B=0, A1 cells=0,
B cells=0. What could be the cause of this discrepancy?
11. What enzyme may be useful in distinguishing papain
anti-Ge2?
12. The beta 1-3 linkage between galactose and N-acetyl- secretions
glucosamine is found in?
13. Represents Type II chain Beta 1-4 linkage between
galactose and N acetyl
glucosamine
14. Represents decreasing concentrations of H antigen O>A2>B>A2B>A1>A1B
on RBCs
15. The ABO genes are located on what chromosome Chromosome 9
16. Which glycosyltransferase is needed before A and B L-fucosyltransferase
antigens are formed?
17. Which reflects the A3 subgroup mixed field reactions with
Anti-A and Anti-A,B.
