The SARS-CoV-2 Antigen Rapid Test (Swab) is a rapid chromatographic immunoassay for the qualitative detection of SARS-CoV-2 Nucleocapsid Protein antigens in swab specimens from feline or canine with suspected SARS-CoV-2 infection. SARS-CoV-2 virus is generally detectable in upper respiratory specimens during the acute phase of infection.
