Abstract

ABO incompatibility of red blood cells leads to brisk complement-mediated lysis, particularly in the setting of red cell transfusion. The ABO blood group is the most clinically significant blood group because of preformed immunoglobulin M (IgM) and IgG antibodies to ABO blood group antigens (isohemagglutinins) in everyone except group AB individuals. In addition to transfusion, ABO incompatibility can cause hemolysis in hematopoietic and solid organ transplantation, hemolytic disease of the newborn, and intravenous immunoglobulin infusion. It is important to prevent ABO incompatibility when possible and to anticipate complications when ABO incompatibility is unavoidable.

Keywords: ABH antigens; ABO blood group; Complement; Hemolysis; Isohemagglutinins; Major incompatibility; Minor incompatibility.
