Modern Blood Banking Study Set 1

ISBT nomenclature for the Xg System is

Antigens in the CH/RG blood group system are described as:

Which antigen is expressed on C₄B complement fragments?

A plasma inhibition study was performed on a patient whose serum sample reacted +/- on all panel cells at AHG. Three sets of A, B, C tubes were set up according to the following scheme: Tube A had 2 drops of patient serum and 1 drop of Ch(a+) Rg(a-) plasma. Tube B had 2 drops of patient serum and 1 drop of Ch(a-) Rg(a+) plasma. Tube C had 2 drops of patient serum and 1 drop of Ch(a+) Rg(a+) plasma. Screening cells were added in triplicate and incubated for 60 minutes at 37°C. The antiglobulin test was performed. All three A tubes reacted at 2+, and the B and C tubes were negative. What antibody is indicated?

The Di^a and Di^b antigens are located on:

Which of the following is true concerning Colton antibodies?

Anti-Sc3 will react with which Scianna phenotype?

An antibody that reacts in the IAT phase of the antiglobulin test and whose antigen expression is depressed by the In (Lu) gene is:

The gene for which blood group antigen is located on the petite arm of the X chromosome?

The high-incidence Gy^a, Hy, and Jo^a antigens belong to which blood group system?

Knops antigens are present in most populations at a rate of:

The following is true regarding anti-Do^a and anti-Do^b.

What blood group antigens are involved in the regulation of complement because they are located on decoy accelerating factor?

Where might you expect anti-Yt^b to react in antibody screening?

How does complement aid in the identification of alloantibodies masked by anti-Ch^a?

Anti-Wr^b has been frequently observed in patients:

Bg antibodies are primarily directed toward antigenic determinants present on:

The Wright blood group antigens belong to which blood group system?

LW has a phenotypic relationship with the antigen.

Both anti-Di^a and anti-Di^b are known to:
