The sera of patients with IgG-myeloma, IgM-macroglobulinaemia and with processes accompanied by high polyclonal Ig-levels were measured by radial immunodiffusion for immunoglobulins, coeruloplasmin, α-2-macroglobulin, C3-component, transferrin, α-1-antitrypsin, α-2-haptoglobin and haemopexin. In the presence of typical changes in the immunoglobulin concentrations, elevation of α-2-macroglobulin was found only if polyclonal Ig was increased. The concentration of the C3 component was reduced only in IgM macroglobulinaemia, that of transferrin only in IgG-myeloma, that of α-2-haptoglobin only in IgM-macroglobulinaemia and in case of increased polyclonal Ig.
