1) Hospital visits themselves can cause infections.
2) Many errors in at-home sample collection can be detected with positive/negative controls, in which case the result is a retest — rather than no test!
But you can detect many of these errors at the lab, and send a retest if necessary. And iterate on sample collection kit.
What you get: more testing, less nosocomial infections.
That’s basically a COVID19 meetup and a great way to *create* positives.
By stopping at-home testing, FDA is forcing you to risk your life to get tested.
