title: [Indirect hemagglutination test for detection of toxoplasma antibodies (author's transl)].
abstract: A micromethod with stable reagents for the simple and rapid detection of toxoplasma antibodies with the indirect hemagglutination test (IHAT) is presented. The results obtained with this method are compared with the titers in the dye test and complement-fixation test and with two IHAT-kits recently offered by commercial firms. We propose to use the IHAT as a supplementary reaction to the methods commonly in use. The relationship between the Sabin-Feldman dye test and IHAT is dependent upon the stage of infection. A very good agreement is obtained with latent toxoplasma infections. On the contrary with some new infections (up to 6 months) the IHAT titer is clearly lower than the dye test titer. This discrepancy opens the possibility of determining the infection stage with a single serum-sample.
