[Value of different serological tests in the diagnosis of various forms of active ocular toxoplasmosis].

The analysis of results of indirect immunofluorescence and direct agglutination reaction in patients with various forms of ocular toxoplasmosis showed that these reactions have a limited value in diagnostics of this condition. One can define a sure diagnosis of active ocular toxoplasmosis when the titre of these reactions are higher than 512. The ELISA IgM reaction is specific for the active form of this disease. The sensitivity of this reaction amounts 43-50%. In cases of iridocyclitis the results of the serological tests were similar to those of the control group; this confirms the hypothesis that the inflammation is evoked by an allergic reaction.
