Column A friend recently texted me in a panic from Florida, where he’d been consoling relatives following a death in the family. Those relatives had returned a positive COVID-19 test, then a negative test. My friend was exposed to them, so got his own test. It came back negative. His relatives were tested again. Negative.
What should he do, he asked me?
Well, I helpfully suggested, why don’t you Google the accuracy of the bog-standard polymerase chain reaction (PCR) test you’ve just had? That’ll give you some error bars and allow you to manage your risks.
