title: Serum proteins in processes associated with an increase in the monoclonal and polyclonal immunoglobulin levels.
abstract: 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, alpha-2-macroglobulin, C3-component, transferrin, alpha-1-antitrypsin, alpha-2-haptoglobin and haemopexin. In the presence of typical changes in the immunoglobulin concentrations, elevation of alpha-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 alpha-2-haptoglobin only in IgM-macroglobulinaemia and in case of increased polyclonal Ig.
