FDA opens door to rapid, at-home screening for COVID-19
Correction & Clarification: This story originally misstated which companies vying to create a fast, cheap at-home coronavirus test would be eligible for $50 million through a competition hosted by XPRIZE.
Other tests are fast, but they're so expensive they're unlikely to be used regularly. A clinic in Massachusetts, for example, charges $160 per rapid test; it's not covered by insurance. But Dr. Michael Mina, an infectious disease epidemiologist at the Harvard T.H. Chan School of Public Health, said the way the FDA's guidance template is written makes it less likely that such crucial tests will reach the general public.
Mina said the standards should be lowered further. People are contagious only when there's an extremely high virus level in their body, which can be detected by a less sensitive test. An infection that goes undetected by a less-sensitive test would be caught a few days later when the person is tested again, he said. Or the person would already be on the way to recovery and probably wouldn't be contagious.
The XPRIZE, a nonprofit that designs and hosts public competitions, announced Tuesday that it would split a $5 million prize among five winners who can produce a test that delivers results in as little as 15 minutes and costs less than $15.
