Abstract
Heterologous anti-lymphocyte globulin (ALG) is known to contain panagglutination activity and may cause a positive direct antiglobulin test in a renal allograft recipient. Three patients are reported in whom the passively acquired antibody showed apparent specificity in the Lutheran blood group system. The sera of these patients and eluates from their red cells displayed reactivity consistent with a Lutheran-related antibody. While the neat ALG acted as a panagglutinin, the Lutheran system specificity appeared only following dilution of the ALG. This specificity did not appear to represent a separate, distinguishable antibody in the ALG product. Before considering the utilization of units of the rare Lu(a-b-) phenotype for transfusing a renal allograft patient who has a Lutheran-related antibody, investigation of ALG as a source of that antibody should be conducted.
