Passively acquired hemagglutinating antibodies may be detected in the serum of patients receiving horse anti‐lymphoblast globulin (ALG) or anti‐thymocyte globulin (ATG). Thirty‐seven patients receiving ALG following renal transplantation were studied. Eight patients monitored daily all developed positive direct antiglobulin tests (DAT) and positive red cell antibody screening tests. Fifteen of 32 recipients developed red cell antibodies reactive at room temperature in saline, 4 of 32 in albumin at 37 degrees C, and 33 of 37 in the antiglobulin test. Horse globulin was detected on the red cells of all six recipients tested with rabbit anti‐horse globulin. Ether eluates prepared from the red cells of 20 patients showed no specificity for common red cell antigens. Anti‐human globulin (AHG), absorbed with ALG‐ coated red cells to remove the component in the AHG which was crossreacting with horse globulin, was used successfully for antibody screening and identification, direct antiglobulin testing, and/or the antiglobulin crossmatching of 27 ALG and ATG recipients, including five with red cell alloantibodies.
