The accuracy of rapid antigen tests varies between tests that are produced by different manufacturers and there is a lack of evidence for many commercially available tests.Rapid antigen tests are considerably less accurate when they are used in people with no signs or symptoms of infection, but do perform better in people who have been in contact with someone who has confirmed COVID-19.People who test negative may still be infected. Rapid antigen tests are most accurate when they are used in people who have signs or symptoms of COVID-19, especially during the first week of illness.Covid-19: Lateral flow tests miss over half of cases, Liverpool pilot data show.

However, there is a low chance they will issue a false positive result.ĭespite these drawbacks, some researchers have suggested that the speed of return and ability to do more frequent tests may make the rapid antigen test more suitable in many cases than a PCR test.
