The major cause of hemolytic disease of the newborn (HDN) due to blood type incompatibility is ABO incompatibility, while HDN due to other alloantibodies (anti-C, anti-c, anti-E, anti-e, and anti-kell) is rare. We describe here an infant diagnosed with HDN due to anti-E antibody (Ab) and anti-c Ab incompatibility following maternal red blood cell (RBC) transfusion received at the previous delivery for post-partum hemorrhage. We examined the blood products transfused to the mother, and the infant’s blood, and we detected alloantibodies in the previously transfused blood products.
