Final week, I used to be about to go on a date, and since I am severely immunocompromised, we agreed he would take a COVID take a look at utilizing one amongst my fast house PCR exams. It was a courtesy—he felt totally unbelievable— nonetheless he examined optimistic. By the subsequent day, he was sick as a canine. And, by the way in which by which by which, the short antigen take a look at he took when he acquired house that evening time time was opposed.

When you can be used to pondering of COVID exams as interchangeable, there’s an unlimited distinction between the identical previous at-home antigen take a look at and a PCR (molecular) take a look at. Practically 5 years in, it’s important to know why PCR exams are these you need when proper testing is crucial.
The excellence between a PCR and a Speedy Antigen Look at
What you usually ponder as a house COVID take a look at—like the type you presumably can order free of price from the government—is a fast antigen take a look at. When these at-home COVID exams grew to show into accessible, that they’d been a strong software program program to assist folks know that they’d been optimistic so they could isolate themselves from others.
