[Model experiments on the effect of IgM- and IgG-antibodies on the reactivity of Treponema pallidum hemagglutination (TPHA)-test]
Abstract
Fractionated sera of patients in different stages of syphilis were examined comparatively with the TPHA-FTA(IgM)- and FTA(IgG)-test. It was shown that the TPHA-test proved to be convenient for early immunologic diagnosis of syphilis. The TPHA-test includes not only IgG anti-treponemal antibodies but also IgM antibodies. In the early stage of syphilis a reactive result of TPHA-test can be related exclusively on treponemal specific IgM antibodies.
