Product Description
One-Step H. pylori Ab Rapid Test is a rapid, one-step, visual test for the for the qualitative detection of antibodies (IgG, IgM, and IgA) anti- Helicobacter pylori (H. pylori) in human serum, plasma, whole blood.
The test is to be used as an aid in the diagnosis of infection due to H. pylori, formely known as Campylobacter pylori, in patients with gastrointestinal symptoms
One-Step H. pylori Ab Rapid Test utilizes the principle of lateral flow immunochromatography, a double antigen sandwich immunoassay on a membrane.
There are two regions, test region and control region, an the membrane of the test strip. The test strip consists of: 1) a burgundy colored conjugate pad containing H.pylori antigens conjugated with colloid gold and rabbit IgG conjugated with colloid gold, 2) a nitrocellulose membrane strip containing a test band (T band) and a control band (C band). The T band is pre-coated with H.pylori antigens, and the C band is pre-coated with goat anti-rabbit IgG antibody.
When an adequate volume of test specimen is dispensed into the sample well of the cassette, the specimen migrates by capillary action across the cassette. The antibodies: either the IgG, the IgM, or the IgA, to H. Pylori if present in the specimen will bind to the H. Pylori conjugates. The immunocomplex is then captured on the membrane by the pre-coated H. Pylori antigens, forming a burgundy colored T band, indicating a H. Pylori Ab positive test result.
The rabbit IgG colloidal gold conjugate and unbound complex if any move further on the membrane and are subsequently immobilized by the goat anti rabbit IgG antibodies coated on the membrane at the control region (C) forming a pink / purple colored band.
