rapid covid test-rapid antigen tests for diagnosing COVID-19
People with suspected COVID-19 need to know quickly whether they are infected, so that they can self-isolate, receive treatment, and inform close contacts. Currently, COVID-19 infection is confirmed by a laboratory test called RT-PCR, which uses specialist equipment and often takes at least 24 hours to produce a result.In many places, rapid antigen tests have opened access to testing for many more people, with and without symptoms, and in locations other than healthcare settings. Faster diagnosis of COVID-19 infection could allow people to take appropriate action more quickly, with the potential to reduce the spread of COVID-19, but it is important to understand how accurate they are and the best way to use them.
