Overview:
Typing paternal RBCs for antigens that correspond to maternal antibody may aid in the prediction of hemolytic disease of the fetus and newborn.
Presence of potent cold autoagglutinins, positive direct antiglobulin test, and, in some cases, bacteremia may interfere with test interpretation. Typing for high or low frequency antigens may not be possible due to the unavailability of appropriate antisera.

Red cell antigen typing may also be indicated for bone marrow, tissue, organ, or blood donors prior to donation. Testing a prenatal patient for red cell antigens is generally not indicated.
