Just googled- rapid covid test accuracy rate
See the article linked. I do not know how old the results of the article you saw are, but the link I posted is from the past month (tests obviously improve with time).
Also, it’s positive the article you saw says the rate of false
negatives is high on rapids, which is still true. That is the exact reverse of the argument you were originally making (that there is a high rate of false
positives).
