Articles like this continue to miss that rapid tests can be used multiple times in a row and paired together for rapid confirmation - immediately.
Bayes theorem is great, but let’s update our thinking around tests when we invoke it.

I want to clarify this 👆is a very nice and well written article by @TomChivers - pertaining to conventional one-off testing
Frequent accessible testing is however different & repeated use of one or more tests must be factored in to sens/spec calculations & Bayes probabilities

Since false pos are of concern bc they mean ppl isolate when they do not need to, then w that definition @TomChivers it would be interesting if you follow up w a piece on the VERY high false pos PCR rate bc many/most PCR positives are detected AFTER the isolation window passed
For some reason very very few want to discuss this crucial piece which is absolutely known - even CDC and others recognize it.
Yet no one talks about it.
Requiring isolation AFTER the 10 day isolation window is complete is as bad as a false positive causing isolation.
