Preanalytic depletion of medicinal anti-CD38 antibody from patient plasma for immunohematology testing

Monoclonal antibodies such as daratumumab that target antigens that are also expressed on red blood cells impede blood group typing. The preferred approach to potential transfusion is to do prior extensive antigen typing of patients' red cells; however, this is not always possible. Ehrend et al...

Description
Summary:Monoclonal antibodies such as daratumumab that target antigens that are also expressed on red blood cells impede blood group typing. The preferred approach to potential transfusion is to do prior extensive antigen typing of patients' red cells; however, this is not always possible. Ehrend et al describe a technique for absorbing the antibodies from serum to allow accurate red cell typing for transfusion.
