Clinical Significance
Antibody screening is for the detection of allo- or autoantibodies direct against red blood cell antigens in the settings of pretransfusion testing. Transfusion and pregnancy are the primary means of sensitization to red cell antigens. Allo-antibodies may cause hemolytic disease of the newborn or hemolysis of transfused donor red blood cells. Autoantibodies react against the patient's own red cells as well as the majority of cells tested. Autoantibodies can be clinically benign or can hemolyze the patient's own red blood cells, such as in cold agglutinin disease or autoimmune hemolytic anemia.
