Any facts on false positives?

With mandatory testing for athletes participating in contact youth sports, there is a tremendous fear of false positives impacting individuals and their teams. Are there any studies that show the rates of false positives for the various tests? I found this from MIT:

And the CDC's commentary is fairly wishy washy, the % of false positives rise when the overall rates of Covid decrease (no kidding). The real question is how many false positives as a percent of tests taken. The MIT study seems to get there. . . .
