Summary and explanation
T. gondii is a ligateintracellular protozoan parasite with a worldwide distribution. Serological data indicate that approximately 30% of the population in most industrialized nations is chronically infected with the organism.A variety of serologic tests for antibodies to T. gondii have been used to aid in the diagnosis of acute infection.and assess previous exposure to the organism. These tests are: Sabin-Feldman stain test, direct agglutination, indirect hemagglutination, latex agglutination, indirect immunofluorescence, and ELISA. Recently, the lateral flow chromatographic immunoassay, such as the rapid Toxo IgG / IgM test, has been introduced in the clinic for the instantaneous detection of T. gondii infection.
