Systematic approach in identification and management of multiple alloantibody: A case of triple alloantibody

Abstract

Alloimmunization is an adverse consequence of exposition to red blood cell antigens through transfusion, pregnancy, or transplantation. Alloimmunization to red cell antigens creates problem not only in immunohematological testing but also causes difficulty in finding compatible blood for those patients who develop multiple alloantibodies. Moreover, the development of multiple alloantibodies can significantly complicate transfusion therapy and/or provokes hemolytic transfusion reactions, the severity of which can vary from mild to extremely severe. We are presenting an interesting case with multiple alloantibodies. Patient's samples were investigated for antibody screening using commercially available three cell panels, and the antibody was identified using different lots of identification panel. Red cell phenotyping was done with minor blood group antisera. After workup, antigen-negative compatible blood was provided for transfusion.
