I've seen discussions of the faulty reagent (which happens, it's a production rollout under lots of stress and pressure). I've also seen through Foreign Policy Garrett's assertion that the Chinese-manufactured tests were rendering "up to" a 50% false negative rate, sometimes requiring 8 tests to render a valid result [1]. What I've yet to see is substantiation of claims online that because of what Garrett reported upon, the CDC chose to create its own PCR test instead of relying upon the Chinese version. If anyone can help me substantiate that, then that would be most welcome as it would explain a fair chunk of the CDC delays. For awhile, I dropped into the rabbit hole of contemplating building my own PCR thermocycler and buying my own RT-qPCR supermix to try to run my own tests, then I acknowledged I didn't know what the hell I was thinking.
