Elon Musk : Something extremely bogus is going on. Was tested for covid four times today. Two tests came back negative, two came back positive. Same machine, same test, same nurse. Rapid antigen test from BD.
Emma Bell PhD : Rapid antigen tests trade sensitivity for speed. They return a result in <30 minutes, but can only detect COVID-19 when you're absolutely riddled with it. What's bogus is that Space Karen didn't read up on the test before complaining to his millions of followers.
