Antigen test

Antigen tests ''are commonly used in the diagnosis of respiratory pathogens, including influenza viruses and respiratory syncytial virus. Antigen tests are immunoassays that detect the presence of a specific viral antigen, which implies current viral infection. Antigen tests are currently authorized to be performed on nasopharyngeal or nasal swab specimens placed directly into the assay’s extraction buffer or reagent. The currently authorized antigen tests include point-of-care, laboratory-based, and self-tests, and they are applicable to people of any age.''
