A rapid antigen test is a lateral flow immunoassay that detects specific proteins (antigens) from a virus, such as SARS-CoV-2. When a nasal swab sample is mixed with a buffer solution and applied to the test cassette, any viral antigens present bind to labeled antibodies, producing a visible colored line within about 15 minutes. Quicking's rapid antigen test follows this well-established principle with optimized reagents for high sensitivity and specificity.
