New research finds that popular at-home antigen tests missed early Omicron infections. But is it because of where people were putting the swabs?
of that test found no change in sensitivity to Omicron, without any real-world data.
But for the moment, no one knows the best way to make those tweaks. There are a lot of options for gathering an oral sample. The Cape Town researchers had participants swab their gums, tongue, cheeks, and palate—and then compared the results to a shallow nose swab. Meanwhile, the UK government“I really hope that [companies like] Abbott and Quiddel do what they have to to really quickly validate throat swabs,” says Wyllie.
Until that data is available though, the solution isn’t to fiddle with the test on your own. Instead, don’t treat a negative antigen test result as definitive. “The big message is that if people are using antigen tests, they cannot ignore symptoms,” says Wyllie. “They cannot ignore a high-risk exposure.
So if you’ve got symptoms, assume for now that you’ve got COVID until you can get a PCR test. If you’ve been exposed to someone, quarantine and take a PCR, rather than an at-home test. In a couple weeks, the FDA might announce that you’ll get more definitive results if you swab your mouth or throat. Just remember, nothing is a silver bullet.
