Clinical Significance

After the A and B antigens of the ABO system, D is the most important red cell antigen in transfusion practice. In contrast to A and B, persons lacking the D antigen on their red cells do not usually have the corresponding antibody. Instead, anti-D is usually formed as a result of a D-negative individual being exposed to the D antigen through transfusion or pregnancy. The D antigen has greater immunogenicity than virtually all other red cell antigens and is associated with the development of Hemolytic Disease of the Newborn and with hemolytic transfusion reactions. Therefore, all recipients and donors are routinely tested for the D antigen to ensure D-negative recipients are given D-negative red cells.
