Elon Musk was tested four times for COVID-19 in one day. 2 tests were positive and 2 tests were negative.

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.
