Clinical Utility

  • Antibody identification is useful in assessing positive antibody screens, transfusion reactions, hemolytic disease of the newborn, and autoimmune hemolytic anemias.
  • Some patients develop antibodies to foreign red blood cells following transfusion, pregnancy or from an unknown stimulus. These antibodies may be capable of destroying transfused red cells or fetal red cells in utero. It is important to identify the antibody specificity in order to determine the antibody's capability of causing clinical harm and if necessary, to avoid the antigen on transfused red blood cells.
