Also Known as (Alias) D,C,E,c and e antigen typing, complete
Indications Determination the likelihood of hemolytic disease of the newborn in cases of maternal antibody, identify compatible blood for recipients with atypical antibodies, identify phenotypically matched blood for recipients likely to receive multiple red cell transfusions to prevent the production of atypical antibodies.
Method Standard test tube methodology, Hemagglutination

A pre-transfusion should be used for antigen typing, if available.  RBC genotyping can provide this information in recently transfused recipients.
