title: Simple method to detect virus-specific IgM antibodies in patients' serum samples after immunosorption of immunoglobulins G and A.
abstract: By absorption with protein A and specific immunosorption using insolubilized adsorbentia (CPG), a method was developed for rapid elimination of IgG and IgA from patients' serum samples. This test technique was examined in the diagnosis of rubella infections, i.e., rubella-specific IgM antibodies. The procedure has proven to be as reliable as determinations carried out with IgM fractions separated on a sucroe density gradient.
