WASHINGTON (AP) The U.S. Food and Drug Administration has approved the first rapid coronavirus test, which produces results in about 45 minutes.

An FDA spokeswoman confirmed the approval after an announcement from Cepheid, a Silicon Valley molecular diagnostics company.

It can take at least a few days to get results from current coronavirus tests, which typically are sent in batches to reference labs, said Dr. David Persing, the company’s chief medical and technology officer.

“What’s really needed is a test that can rapidly determine status of infection on site when patients are being seen,” he said on a company video.

Cepheid said it will begin shipping its tests next week.
