It didn't lose it.
I'm not about to try to prove these test mean shit. Mainly because I'm never having one done, so I don't really give a fuck whether they work or not. You've misunderstood the memo though.
The CDC withdrew their request for EUA from the FDA for their RT-PCR test.
There are literally hundreds of other manufacturers of these PCR tests that are still authorized and even more that aren't PCR.
Regardless of whatever video people post, the battle hasn't been won.
