Positive results from at-home COVID-19 tests are reliable. However, at-home tests are more likely to produce false-negative results, meaning the individual has an active COVID-19 infection but the test does not accurately return a positive result. If you are experiencing symptoms of COVID-19 and an at-home COVID-19 test produces a negative result, continue testing yourself as long as your symptoms persist. If your symptoms worsen and you continue to receive negative test results from at-home COVID-19 tests, seek a PCR test from a health care provider for a more accurate test result. At-home tests should be used around 5 days after a potential exposure to COVID-19, if you are currently experiencing COVID-19 symptoms, and immediately before you attend an indoor event where you will be around other people.
