Description
Intended Use: This product is used to qualitatively detect the novel coro-navirus (SARS-CoV-2) antigen in human nasal throat swabs or oral throat swabs. It can only be used for scientific research and cannot be used for in vitro testing.
Test Principle: This product adopts colloidal gold immunochromatography technology, spraying colloidal gold labeled SARS-CoV-2 mono-clonal antibody 1 on the gold pad The SARS-CoV-2 monoclonal antibody 2 is coated on nitrocellulose membrane as the test line (T line) and goat anti-mouse IgG antibody is coated as the quality control line (C line). When an appropriate amount of the sample to be tested is added to the sample hole of the test card, the sample will move forward along the test card under capil-lary action. If the sample contains a SARS-CoV-2 antigen, the antigen will bind with the colloidal gold labeled SARS-CoV-2 monoclonal antibody 1, and the immune complex forms a complex with the coated SARS-CoV-2 monoclonal antibody 2 at the T line, showing a purple-red T line, indicating that the SARS-CoV-2 antigen is positive. If the test line T does not show color and shows a negative result, it means that the sample does not contain the SARS-CoV-2 antigen. The test card also contains a quality control line C, regardless of whether there is a test line, the purple-red quality control line C should appear. If the quality control line C does not appear, it indicates that the test result is invalid, and this sample needs to be tested again
