PITTSBURGH (KDKA) – COVID-19 testing always focused on the nose. It’s quicker, less uncomfortable and experts thought it collected a good enough sample of the virus. But now some doctors think we might be swabbing the wrong place.

It would look just like a strep test, that long q-tip would first swab the back of your throat. You could either stop there, or also swab your nose. The FDA is against it, but some doctors say it’s getting better results.

Just scroll through #sciencetwitter and you’ll find the people trying it out. Many people are struggling with sore throats, claiming when they swabbed their noses, they tested negative, but when they swabbed their throats, the results changed.
