(Reuters) - Tesla Inc Chief Executive Officer Elon Musk questioned the accuracy of COVID-19 tests on Thursday after claiming that results showed he tested positive twice and then negative twice all on the same day.

"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," Musk said in a tweet, possibly referring to Becton Dickinson and Co's rapid antigen test.
