As usual they're taking something with a kernel of truth and running sideways misrepresenting it.
Whole bunch of false positives.
There's more like that out there.
Don't remember where I read it or if it's true but something about a bunch of test kits sent in that were never actually done on anyone and those coming back positive.
I don't know how widespread it is but have read other things where legit medical folks question the accuracy of some of these type of test.
Part of the reason why they require 2 or 3 negatives in a row for an actual medical worker to go back to work.
No, I don't have a library of links saved up for every little thing.
