Rapid SARS-CoV-2 Antigen Test Card is an immunochromatography based one step in vitro test. It is designed for the rapid qualitative determination of SARS-CoV-2 virus antigen in nasal swabs, nasopharyngeal swabs or oropharyngeal swabs from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset. Rapid SARS-CoV-2 Antigen Test Card can not be used as the basis to diagnose or exclude SARS-CoV-2 infection. Rapid SARS-CoV-2 Antigen Test Card detects the SARS-CoV-2 nucleocapsid protein (N protein). Theoretically, genetic SARS-CoV-2 variants with non-nucleocapsid protein mutations do not affect the product performance
