COVID-19 Ag Test is the chromatographic assay used for qualitative detection of the COVID-19 antigen in human nasal swab specimen.This test kit uses COVID-19 monoclonal antibody and goat anti-mouse IgG polyclonal antibodies that are respectively immobilized on a nitrocellulose membrane. It uses colloidal gold to label sufficient COVID-19 monoclonal antibody. Using nano-colloidal gold technology and applying highly specific antibody-antigen reaction and immunochromatographic analysis technology principle. When testing, the COVID-19 antigen in the sample combined with the colloidal gold-labeled COVID-19 monoclonal antibody to form a complex, which was then combined with the COVID-19 monoclonal antibody coated in the T line during chromatography, at this time there is one red line in the T area .When the samples do not contain COVID-19 antigen, colloidal gold-labeled COVID-19 monoclonal antibody cannot combined with COVID-19 monoclonal antibody in the T line region, so there is no red colored line in the T area .Regardless of the presence of COVID-19 antigen in the sample, a red line will form in the quality control area (C). The red line appears in the quality control area (C) serves as 1.verification that sufficient volume is added. 2.That proper flow is obtained 3. And as a control for the reagents.
