What do you think of Michael Minas's idea that PCR is the wrong test for public health? It's TOO sensitive, yielding positive for inert RNA fragments. We need to test whether we're infectious. $1 10-minute home tests. Positive? Stay home until negative.https://www.theatlantic.com/health/archive/2020/08/how-to-test-every-american-for-covid-19-every-day/615217/ …

That's another argument entirely, and a very interesting one

Our little chat just now and a tweet from last week have helped a few things fall into place for my understanding of where the widespread application of a % is going wrong. At last. I owe *you* one for that.

the argument being made, at least in Texas, isn't about PCR. The claim is that a + Ag test is likely false. "we don't know what a +Ag test means without symptoms so it's not a case."
-
and Oregon state University, who are mass testing students then saying the positives are most likely false.

1. you linked to a page to backup your far too high 99.9% claim. But that figure was not mentioned. 2 You left out the fact that PCR test pick up viral fragments and call them a +ve "case". This is far more significant than the other cause.

A good lab (indeed most labs) do not say the person is positive. They report that SARS-COV-2 was detected. Up to the clinician/process pathway to decide what that means.
