The test-kit that the CDC sent to local labs had a faulty reagent, so all test requests have to be sent back to the CDC.[0]
Local labs could develop or purchase their own test kits, but during an a public health emergency, they must get FDA authorization before launching such a test.[1]
This seems to me like a giant institutional and bureaucratic screw up.
Hopefully the FDA may be finally getting its act together and fast-tracking approval of local tests: https://twitter.com/ScottGottliebMD/status/12330216819181936...
