Any facts on false positives?

Thanks. Makes good sense, though seems that .5% is fairly high, especially looking at the rate at MIT. With the testing positivity rate of 2.9% in CoCoCo, then the % of total of false positives would be very significant. Anecdotally, my daughter's school has been testing weekly of late (over 300 per week), with no positives over the last few weeks. Two indeterminate, but that's it.
