The Coronavirus Ag Rapid Test Cassette (Swab) is an in vitroimmunochromatographic assay for the qualitative detection of nucleocapsidprotein antigen from SARS-CoV-2 in direct nasal swabs directly from individuals who are suspected of COVID-19 within the first ten days of symptom onset. It is intended to aid in the rapid diagnosis of SARS-CoV-2 infections.
