SpaceX CEO Elon Musk revealed in a dissatisfied tweet in the early hours of Friday morning that after four rapid virus tests, the coronavirus was tested twice, two positive and two negative. Times. The announcement comes just a few days before the launch of his company’s much-anticipated Crew Dragon capsule, which will carry four astronauts to the International Space Station.
Antigen tests for finding coronavirus protein fragments are cheap and convenient, and the results can usually be communicated to people within minutes. However, they are also less reliable than laboratory tests that use a technique called polymerase chain reaction or PCR, which can look for fragments of genetic material. PCR-based tests are widely regarded as the gold standard for the diagnosis of infectious diseases.
Mr. Musk’s testing problems may arise at high-risk moments. If he does get infected, NASA may not allow him to visit with four astronauts on Sunday, as he did with Robert Benken and Douglas Hurley before the successful launch in May.
After expressing frustration with the results of the quadruple antigen test, Mr. Musk immediately told his followers that he had looked for a PCR-based follow-up test that would give an answer within 24 hours.
A few hours later, Mr. Musk repeatedly expressed disappointment with the pandemic and its economic impact. He came to Twitter again, questioning the validity of PCR-based tests, and asked his followers to educate his diagnostic tools. May produce false positives.
When Musk announced his test was full of similar skepticism, but at the same time was encouraged and mocked. Some people baselessly argue that his mixed results prove that the recent rise in coronavirus cases has been exaggerated. Others pointed out that in the context of a country that is still struggling to obtain a coronavirus diagnosis, his repeated tests played a discordant tone.
