Someone I know tested positive a few weeks back. Her work required another test. That came back positive. They told her the following Monday would be the end of the quarantine and she could come back to work then. They said to try to get another test before then just to be safe. If positive, come back Monday and if negative come back Monday. Why waste time/money on the test in that scenario?
Those supplying the tests are one of several making a killing on this scamdemic.
