Abstract
We reviewed HLA antibody testing results using an enzyme-linked immunosorbent assay (ELISA) for all male blood donors at our institution during a 3.5-month period to look for HLA immunization. Confirmatory testing of 33 blood samples positive for HLA class I and/or II antibodies was performed using the fluorescent bead method. A retrospective review of recipients of packed RBCs and platelets processed from these 33 HLA-immunized male donors were conducted to identify transfusion-related acute lung injury and cognate antigens. The agreement rates between the methods for HLA class I and II antibodies were 21% (7/33) and 6% (2/33), respectively. We noted HLA antibodies in the male donors corresponding to cognate antigens in 2 recipients of packed RBCs and in 3 recipients of platelets. Of 8 donors positive for HLA antibodies, 5 did not have a history of blood transfusion. We conclude that ELISA was too sensitive and had a high false-positive rate for the detection of HLA class II antibodies.
