Last week, I was about to go on a date, and because I’m severely immunocompromised, we agreed he would take a COVID test using one of my rapid home PCR tests. It was a courtesy—he felt perfectly fine— but he tested positive. By the next day, he was sick as a dog. And, by the way, the rapid antigen test he took when he got home that night was negative.

Regardless of how you much of a health risk you see in COVID, it is still, at best, an inconvenience that costs you days off work. A simple home PCR test saved me from that inconvenience (and worse), and if I’d relied on the common rapid antigen test or done nothing at all, I would probably be sick right now.
