I have not been tested. My employer offers them but I go to work so rarely that there hasn’t seemed the need, nor the opportunity without a special trip to be exposed to others. We are not 100% isolated at home, but we aggressively reduce our exposure to crowds always and to long intervals indoors in public insofar as is practical.
My wife was tested several times back in the summer preparatory to various medical procedures. All came back negative.
My aged MIL has been tested several times in her elder living facility following exposure to an infected worker. She tested positive twice in a row, was quarantined, and has not tested positive since. She suffered nothing worse than a cold for a 3 or 4 days; the tests might even have been false positives although I don’t think that’s very likely.
