When it comes to medical testing, high accuracy should not be conflated with predictive value.

A positive result on a test that's 90%+ accurate may imply only a ~50% chance of actual infection. Given a positive test result, the likelihood of actual infection is highly dependent on the prevalence of the disease.
Or you can make it simpler: Where there is zero prevalence (say in New Zealand) even a positive test that’s 99.5% accurate implies a 0% chance of infection.

And how is zero prevalence determined?

The PCR tests don't have false positives. There can be an error in the machine but if it's truly positive, there's covid RNA there. You can also confirm it with lung CT.

Read my question in context. You're response is more of a contradiction to the post I replied to than to mine.

I'm aware, but that post can be explained with antigen test that do have false positives.

You'd have to PCR the whole population at once to establish that scenario of zero prevalence firmly enough to then say with absolute certainty that a positive on a rapid means nothing.

You would think that he would know that the IS NO COVID bill.

They lumped them together so that anyone who voted against it could be attacked for voting against Covid relief.

That would work for lefties. But in any event, don't you get a choice of which arm to have the vaccine given?
