Abstract
A 5-year-old male with sickle cell disease presented with pain, dark urine, and fatigue 10 days after a red blood cell (RBC) transfusion. Laboratory evaluation demonstrated severe anemia, blood type O+, and anti-D in the serum. Anti-D in a D+ patient led to RH genotyping, which revealed homozygosity for RHD∗DAU4 that encodes partial D antigen. Anti-D in this patient whose RBCs exclusively express partial D caused a delayed hemolytic transfusion reaction after exposure to D+ RBCs. The finding of anti-D in a D+patient should be investigated by molecular methods to help distinguish an alloantibody from an autoantibody.
