Intended Use

CO-Check COVID-19 Rapid Antigen Test is a lateral flow immunoassay intended for the qualitative detection of nucleocapsid antigen from SARS-CoV-2 in nasal swab from individuals who show COVID-19 symptoms or considered as high-risk.

​

Nucleocapsid protein is more stable than the other proteins in the SARS-CoV-2 virus (not in the variant region of the mutant virus), therefore it is the major target protein of rapid antigen tests.
