Antibody Identification, Erythrocytes
Clinical Information: After exposure to foreign red blood cells via transfusion or pregnancy, some
people form antibodies which are capable of the destruction of transfused red cells or of fetal red cells in
utero. It is important to identify the antibody specificity in order to assess the antibody's capability of
causing clinical harm and, if necessary, to avoid the antigen on transfused red blood cells.
Useful For: Assessing positive pretransfusion antibody screens, transfusion reactions, hemolytic
disease of the newborn, and autoimmune hemolytic anemias
Interpretation: Specificity of alloantibodies will be stated. The patient's red blood cells will be typed
for absence of the corresponding antigen(s) or as an aid to identification in complex cases. A consultation
service is offered, at no charge, regarding the clinical relevance of red cell antibodies.
Reference Values:
Negative
If positive, antibodies will be identified and corresponding special red cell antigen typing on patient's red
blood cells will be performed. A consultation service is offered, at no charge, regarding the clinical
relevance of red cell antibodies.

Antibody Screen, Erythrocytes
Clinical Information: Transfusion and pregnancy are the primary means of sensitization to red cell
antigens. In a given population, 2% to 4% of the general population possess irregular red cell
alloantibodies. Such 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 hemoyltic anemia.
Useful For: Detection of allo- or autoantibodies directed against red blood cell antigens in the settings
of pretransfusion testing Evaluation of transfusion reactions Evaluation of hemolytic anemia
Interpretation: A positive result (antibody detected) necessitates antibody identification to establish
the specificity and clinical significance of the antibody detected. Negative–no antibody detected.
Reference Values:
Negative
If positive, antibody identification will be performed.
