As a slightly neurotic person who writes about health for a living, I used to get a lot of COVID-19 PCR tests. But I haven’t had one in recent memory—not because I’ve stopped screening myself for COVID-19, but because I’ve switched to testing at home.

The experts I interviewed said at-home tests work well for most of the average person’s testing needs, but there are still some situations when it makes sense to get a PCR test, the gold standard for diagnostic accuracy.

"Getting Americans used to a time when we can have some diagnostic certainty is not a bad thing. We shouldn't just accept pure treatment [without tests to confirm a diagnosis]."
