title: IgM-kappa-lambda biclonal gammopathy elucidated by immunofixation electrophoresis.
abstract: A patient with alcoholism-related illness was found to have a rarely encountered biclonal gammopathy with IgM-kappa and IgM-lambda components. The para-protein bands were readily identified by immunofixation electrophoresis but were not by conventional immunoelectrophoresis. This patient is most appropriately classified as a biclonal gammopathy of undetermined significance, since no cause for this abnormality was found. The literature on biclonal IgM-kappa-lambda gammopathy is reviewed.
