【SUMMARY】

  T. gondii is an obligate intracellular protozoan parasite with a worldwide distribution1,2. Serological data indicates that approximately 30% of the population of most industrialized nations is chronically infected with the organism3. A variety of serologic tests for antibodies to T. gondii have been used as an aid in diagnosis of acute infection and to assess previous exposure to the organism. These tests are the Sabin Feldman dye test, direct agglutination, indirect hemagglutination, latex agglutination, indirect immunofluorescence, and ELISA. Recently, lateral flow chromatographic immunoassay, such as The Toxo IgG/IgM Rapid Test Cassette was introduced into the clinic for the serodiagnosis of T. gondii infection.

【PRINCIPLE】

  The Toxo IgG/IgM Rapid Test Cassette is a lateral flow chromatographic immunoassay. The test consists of: 1) a red colored conjugate containing recombinant T. gondii antigens conjugated with colloid gold (T. gondii conjugates) and rabbit IgG gold conjugates, 2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with monoclonal anti-human IgM for detection of IgM anti-T. gondii, T2 band is pre-coated with reagents for detection of IgG anti-T. gondii, and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is applied into the sample pad of the test, the specimen migrates by capillary action across the strip. IgM anti-T. gondii if present in the specimen will bind to the T. gondii conjugates. The immunocomplex is then captured on the membrane by the pre-coated anti-human IgM antibody, forming a red colored T1 band, indicating a T. gondii IgM positive test result. IgG anti-T. gondii if present in the specimen will bind to the T. gondii conjugates. The immunocomplex is then captured by the pre-coated reagents on the membrane, forming a red colored T2 band, indicating a T. gondii IgG positive test result. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a red colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device.
