This test is an assay for detecting SARS-CoV-2 infections using anterior nasal swab samples. Immunochromatographic assay technology is utilized as its measurement principle. The test consists of a cassette device containing anti-nucleocapsid protein monoclonal antibodies directed against SARS-CoV and SARS-CoV-2. The sample well contains the anti-nucleocapsid protein monoclonal antibody binding gold colloid.

If the SARS-CoV-2 antigen is present in the specimen, the solubilized conjugate migrates with the sample by passive diffusion and the conjugate and sample material come into contact with the anti-SARS-CoV-2 antibodies adsorbed onto the nitrocellulose. The result will be finished within 15 minutes and show as a red line on the strip.
