As the Omicron variant spreads, many have turned to regular rapid COVID-19 antigen testing for peace of mind.
But how trustworthy are the results of a rapid COVID-19 test?.
In December, during the onset of the Omicron variant, the US Food and Drug Administration updated its guidance to note:.

Experts say rapid tests are more likely to work when coronavirus symptoms are present.
Wait a day, maybe two into symptoms to use your test because people are becoming symptomatic a day or so before they're turning positive.

Officials suggest one negative rapid test is not conclusive evidence that a coronavirus infection isn't present.
If you're negative after two rapid tests but still experiencing symptoms, consider testing a third time with a rapid test or getting a PCR test if you can.
