Extended red blood cell antigen matching for transfusions in sickle cell disease: a review of a 14-year experience from a single center (CME).

Background: Alloimmunization to red blood cell (RBC) blood group antigens is a major complication for patients with sickle cell disease (SCD), which limits the usefulness of RBC transfusion. Here, we report our experiences with extended RBC antigen matching for SCD patients.

Study Design And Methods: Records for 99 SCD patients transfused only with the extended matching protocol between 1993 and 2006 were reviewed.
