But for the outbreaks raging now, he said, what’s needed are coronavirus tests that are fast, cheap and abundant enough to frequently test everyone who needs it — even if the tests are less sensitive."

"For months, the call for coronavirus testing has been led by one resounding refrain: To keep outbreaks under control, doctors and researchers need to deploy the most accurate tests available — ones reliable enough to root out as many infections as possible, even in the absence of symptoms.
That’s long been the dogma of infectious disease diagnostics, experts say, since it helps ensure that cases won’t be missed. *During this pandemic, that has meant relying heavily on PCR testing, an extremely accurate but time- and labor-intensive method that requires samples to be processed at laboratories.*
*But as the virus continues its rampage across the country and tests remain in short supply in many regions, researchers and public health experts have grown increasingly vocal about revising this long-held credo.
