A female patient developed serious hemolysis in association with the injection of a radiographic contrast medium (RCM). Serologic investigation of her serum suggested complement-mediated hemolysis, induced by an RCM-dependent IgM antibody in her serum. The antibody was of high titer and low avidity. The antibody showed cross-reactions with related radiographic contrast media and reacted only with group I adult RBCs.
