[Transfusion management of patients with red blood cell antibodies].

Introduction: Red blood cell antibodies may cause a positive result of pre-transfusion blood compatibility testing (crossmatch test). It can be a problem to provide suitable blood units for patients with clinically significant antibodies to high-frequency antigens as well as for those with multiple alloantibody specificities. This study was aimed at identifying transfused patients in the population of South-Backa who had developed clinically significant red blood cell alloantibodies.
