I recently spent time in the hospital, got tested for some things and only one of which I'm certain for. I was in there for a broken bone. If you've had a swab shoved up your nose to look for covid-19 it is not a comforting experience. I also got the other nostril swabbed (not so far up) and two rectal swabs (not comforting either.) Yet, I don't know what the testing was for. Which would leave open the question: were they all Covid tests or no? All tests came back negative, really whatever that means.
