A<unk>  <unk> , sometimes called a rapid<unk>  detection test (RADT),<unk>  rapid test (ART), or just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an<unk> . Rapid tests are a type of lateral flow test that detect<unk> s, distinguishing it from other medical tests that detect antibodies (antibody tests) or nucleic acid (nucleic acid tests), of either laboratory or point-of-care types. Rapid tests generally give a result in 5 to 30 minutes, require minimal training or infrastructure, and have significant cost advantages.<unk> s for the detection of SARS-CoV-2, the virus that causes COVID-19, have been commonly used during the COVID-19 pandemic. For many years, an early and major class of<unk> s—the rapid strep tests for streptococci—were so often the referent when<unk> s or RADTs were mentioned that the two latter terms were often loosely treated as synonymous with those; today, more precise usage is advisable, as other major classes of<unk> s are just as important.<unk> s are based on the principle of<unk> -antibody interaction. Antibodies directed against the SAR-CoV-2 virus<unk> s, which are proteins on the surface of the virus, will detect the virus in the nasopharyngeal sample. A positive result with an<unk>  test will need to be confirmed by an RT-qPCR test.
