Useful For
Discover the ABO and Rh antigens on recipient red cells and presence of anti-ABO antibodies in recipient plasma. Necessary to prevent ABO incompatible blood product transfusions. In addition, plasma is tested against red blood cells with known antigens to recognize new/existing antibodies that may cause hemolysis after transfusion.
Patient Preparation
No special patient preparation required
