The coronavirus test should be well timed to ensure the best possible result. For this reason, situations may arise where a retest is recommended if the first test is negative.
Last week CEO of the electric car company Tesla Elon Musk said on Twitter that he underwent four coronavirus tests on the same day. Two tests proved positive, two negative.
“There’s something extremely bogus about here. We did four corona tests on the same day. Two came back negative, two positive. Same machine, same test, same caregiver. It was a rapid antigen test, ”Musk wrote on Twitter.
