[Determination of thyroglobulin autoantibodies using enzyme immunoassay, radioimmunoassay and passive hemagglutination].

Abstract

A solid-phase enzyme immunoassay, a radioimmunoassay and the passive hemagglutination were tested for the determination of antithyroglobulin autoantibodies. The antibody-titres detected with these methods showed a good correlation. The sensitivities of the solid-phase immunoassays are four times higher than the sensitivity of the passive hemagglutination. For the diagnosis of thyroid autoimmune diseases the enzyme immunoassay.
