Anti-G antibody in alloimmunized pregnant women: Report of two cases.

ABSTRACT

Anti-G has been reported as a possible cause of hemolytic disease of the fetus and newborn (HDFN), either independently or in association with anti-D, anti-C or both. The antibody mimics the pattern of anti-C and anti-D reactivity in the identification panel and is often present along with either or both of these antibodies. The differentiation of anti-D, -C and-G in routine pretransfusion workup is particularly essential in antenatal cases. We report two antenatal cases where anti-G was identified on advanced immunohematological workup, in addition to other alloantibodies.
