SBB COMPREHENSIVE UPDATED EXAM QUESTIONS AND
ANSWERS GRADED A+
✔✔Initial testing at immediate spin tube testing gives the following results. Of the
following choices, which is the most probable cause of these reactions?
Anti A - 0; Anti B- 0; Anti D - 3+; A1 cells - 4+; B cells - 4+; O cells - 4 +; Auto CT - 0 -
✔✔Group O with unexpected antibody
✔✔To differentiate anti-Fy3 from anti-Fy-5, one should test which cells? - ✔✔Fy(a+b+),
Rh null
✔✔A prenatal patient has an anti-M that is reactive with polyspecific AHG. What testing
can be performed to determine the clinical significance of this antibody? - ✔✔DTT treat
the patient's serum and retest
✔✔The following results are obtained when testing polyagglutinable cells with a panel of
lectins. What type of polyagglutination is present?
Arachis hypogea - +
Dolichos biflorus - 0
Glycine soya - +
Salvia sclarea - 0
Salvia horminum - 0 - ✔✔T
✔✔A patient has an antibody that reacts 2+ with cells at IAT. A complete phenotype of
the patient's red cells showed: Group A, R2R2, K-k+, M+N+S-s+, Jk(a-,b-), Fy(a-b+).
What is the likely antibody? - ✔✔Anti-Jk3
Jk(a-, b-) phenotype is very rare. These individuals can make an anti-JK3. Found in
Polynesian people.
✔✔A saline-reactive antibody is strongly positive with all adult cells, including the
autocontrol, as well as cord cells. The enzyme panel is negative. The antibody is most
likely? - ✔✔Anti-Pr
✔✔A patient plasma tested positive with all cells tested using column technology. The
following results were obtained when the plasma is testing with cells treated with blood
bank chemicals. Of the following list, which is the most likely antibody?
Ficin all 3+ DTT - 0
a. Anti-Dob
b. Anti-Ge2
c. Anti-EnaFR
d. Anti-Lub
e. Anti-U - ✔✔D. anti-Lub
