Low incidence of D alloimmunization among patients with a serologic weak D phenotype after D plus transfusion

摘要

BACKGROUNDBy consensus definition, the red blood cells (RBCs) of patients that react weak to 2+ in the serologic D test are classified as having the serologic weak D phenotype (weak D). The risk of D alloimmunization in patients with weak D is not well studied. This study retrospectively determined the incidence of D alloimmunization in patients with weak D who received D+ blood products.
