I had the test.
Before the hospital would allow me to enter for surgery, it was required. Only do the test if you are required. I think my sinuses are still suffering the ramifications.
A six inch swab goes in through the nostrils and strokes the brain, or, well, whatever it reaches. Probably not the brain. Probably something deep in the breathing system. It feels like the brain.
I was negative. For that one moment in time, and not before and not beyond, I tested negative.
