Considering the context that I replied to is "we should also be aware of the danger of false positives", I think given the FDA source I posted (and what I've read elsewhere) I can say that there is absolutely no need to be aware of a danger of false positives in terms of disrupting people's lives.
If you want to argue on the fact of life that nothing in life is absolute. Fine. you win. If administered properly, and the test kit detects a presence of COHVID-19 RNA in your body, and the person telling you the results is not drunk, then the results is as close as 0% as practical.
