Plastic Cassette IgG Toxo Rapid Lab Test Kit with Shelf Life of 2 Years

The Toxo IgG Rapid Test Cassette is a lateral flow chromatographic immunoassay for the simultaneous detection and differentiation of IgG anti-Toxoplasma Gondii (T. gondii) in human serum or plasma. This kit is intended to be used as a screening test and as an aid in the diagnosis of infection with T. gondii. Any reactive specimen with the Toxo IgG Rapid Test Cassette must be confirmed with alternative testing method(s) and clinical findings.

The Toxo IgG Rapid Test Cassette is a lateral flow chromatographic immunoassay. The test consists of: 1) a colored conjugate containing recombinant T. gondii antigens conjugated with colloid gold (T. gondii conjugates) and mouse IgG-gold conjugates, 2) a nitrocellulose membrane strip containing a test band (T band) and a control band (C band). The T band is pre-coated with monoclonal anti-human IgG for detection of IgGanti-T. gondii , and the C band is pre-coated with goat anti mouse 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. IgG 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 monoclonal anti-human IgG, forming a colored T band, indicating a T. gondii IgG positive test result.Absence of any T band (T) suggests a negative result. The test contains an internal control (C band) which should exhibit a colored band of the immunocomplex of goat anti mouse IgG/mouse IgG-gold conjugate regardless of the color development on the T band. Otherwise, the test result is invalid and the specimen must be retested with another device.
