Additional Information

Diagnose myeloma, macroglobulinemia of Waldenström. Immunofixation is used to evaluate monoclonal gammopathy (M protein) found on serum protein electrophoresis; evaluate amyloidosis. Has application to the evaluation of lymphoproliferative disease (malignant lymphoma and others) and collagen disease in general. Of use in the diagnosis and characterization of immune deficient and dysgammaglobulinemic states.
