Abstract
|
|
|
|
Pre-transfusion laboratory tests include ABO and RhD typing, antibody screening test, antibody identification test, and cross-matching. The objective of pre-transfusion testing is to ensure that serologically compatible blood products are administered to patients, thus preventing transfusion complications. Rhesus (Rh) system is considered the second most important after the ABO system, as Rh antigens are highly immunogenic and anti-Rh antibodies can cause hemolytic transfusion reactions (HTR) and hemolytic disease of the fetus and newborn. HTR caused by anti-Rh antibody usually results in delayed onset HTR. There is little information on whether antibodies against C and e antigen can elicit acute hemolytic transfusion reaction. We present here, a rare case of acute hemolytic transfusion reaction caused due to antibodies against C and e antigens, which were not detected during our pre-transfusion protocol.
