c (Symptoms of hemolytic transfusion reactions are fever, chills, flushing, chest and back pain, hypotension, nausea, dyspnea, shock, renal failure, and DIC. Circulatory overload, allergic, and anaphylactic reactions are not characterized by fever.) 78) A family has been typed for HLA because 1 of the children needs a stem cell donor. Typing results are listed below:
child #1: A1,2;B8,12
child #2: A1,23;B8,18
child #3: A3,23;B18,?
What is the expected B antigen in child #3?
b. anti-Jka, Jkb, C, and E
Enzyme techniques are particularly useful in the identification of antibodies in the Rh system (e.g., anti-C and E) and in the Kidd system (e.g., anti-Jka and Jkb).
Enzymes destroy some antigens, such as M, N, S, Fya, and Fyb. Therefore the corresponding antibodies would not be detected.
Cells must contain antigens to challenge 18 Ags
