Kidd | delayed transfusion reactions |
High-titer, low avidity antibodies (HTLA) | detected at AHG phase, Chido (Cha) and Rodgers (Rga) |
Antibodies to medication | suspected if nothing is found in elution |
Low incidence antigens | antibody screen neg, but incompatible crossmatch |
Adsorption | removing antibodies from serum |
Elution | removing antibodies from RBCs |
IAT | determines if antibodies to RBC antigens have been produced |
DAT | determines whether auto or allo antibodies are present |
Destroyed by enzymes | Fya, Fyb, S, M, N |
Enhanced by enzymes | Rh, Kidd, Lewis |
Allogenic | donation to general pool |
Autologous | donation by patient for their own use later on |
Segment | where blood is obtained for crossmatch |
