Summary and Explanation

T.gondiiis anobligateintracellular protozoan parasite withaworldwide distribution.Serological data indicates that approximately 30% of the population of most industrializednations is chronically infected with the organism.A variety of serological tests for antibodies to T. gondii have been used as an aid in diagnosisof acute infection and to assess previous exposure to the organism. These tests are: theSabin-Feldman dye test, direct agglutination, indirect hemagglutination, latex agglutination,indirect immunofluorescence, and ELISA. Recently, lateral flow chromatographicimmunoassay, such as the Toxo IgG/IgM Rapid Test has been introduced to the clinicfor the instant detection of T. gondii infection.
