Anti-G with Concomitant Anti-D and Anti-C in a Pre-natal Patient, in India: Multi-disciplinary Approach to Diagnosis...

'G' antigen belongs to the Rh family and it was first described by Allen and Tippet in 1958. Various anti-D, anti-C, and anti-G antibody combinations can be found in patients. Ruling out the presence of anti-D is important for administering RhIg prophylaxis in RhD-negative pregnant women to prevent hemolytic disease of fetus and newborn (HDFN). RhIg prophylaxis is not indicated in the presence of an anti-D antibody. Time-to-time monitoring and follow-up of cases of RhD-negative pregnant women with a multi-disciplinary approach including an obstetrician, neonatologist, and transfusion medicine specialist helps diagnose, manage, and monitor HDFN in such cases. This case report emphasizes the need for proper antibody identification (anti-G) and managing HDFN (with intrauterine transfusions and exchange transfusion) during the perinatal period.
