The COVID-19Rapid AntigenTest is a qualitative membrane-based assay for the detection of SARS-CoV-2 in nasopharyngeal swab specimen. The target antigen in the specimen, if present, will react with gold conjugated anti-SARS-CoV-2 antibody and form an antibody-antigen complex. As this complex migrates along the length of the nitrocellulose membrane, it is captured by pre-coated anti-SARS-CoV-2 antibody located in the test(T) region on device test area, causing a pale to dark pink-purplish band. If the specimen does not contain SARS-CoV-2 antigens, no coloured line will appear in the test line region, indicating a negative result. To serve as a procedural control, a coloured line will always appear in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
