Anti-Rotavirus antibody rapid test card

INTENDED USE

Toxoplasma igg/igm Rpid Test is a rapid immunochromatographic test for the simultaneous detection of IgM and IgG antibodies to Toxoplasma gondii in human serum/plasma. The test can be used as a screening test for Toxoplasma infection and as an aid for differential diagnosis of the self limiting primary Toxoplasma infections and the potentially fatal secondary Toxoplasma infections in conjunction with other criteria.

TESTÿÿPRINCIPLE
The Toxoplasma IgG/IgM Rapid Test is a lateral flow chromatographic immunoassay. The test cassette consists of: 1) a burgundy colored conjugate pad containing Toxoplasma recombinant envelope antigens conjugated with colloidÿÿgold (Toxoplasma 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 the antibody for the detection of IgM anti-Toxoplasma, T2 band is coated with antibody for the detection of IgG anti-Toxoplasma, and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgM anti-Toxoplasma if present in the specimen will bind to the Toxoplasma conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a Toxoplasma IgM positive test result and suggesting a recent or repeat infection. IgG anti-Toxoplasma, if present in the specimen, will bind to the Toxoplasma conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a Toxoplasma IgG positive test result and suggesting a fresh infection.
