Governments and companies across the world put faith in the idea of an 'antibodies test' designed to detect whether someone has had COVID-19 Optimism was dented after scientists revealed that none of the tests they tried were accurate enough to be of use
Different from the nasal and throat swabs that tell you whether you currently have COVID-19, the disease caused by the coronavirus, the antibody test — also called the serology test — looks a bit like a pregnancy test, with results on a series of lines on a strip. It takes just 20 minutes to complete, and can be done at home or at a pharmacy.
This led to fears that some people might seek infection so they could recover and return to work, but for those who had genuinely survived the virus, it held the promise of a degree of freedom. As the widespread societal lockdowns covering much of the world continue in a bid to buy time until a vaccine can be found, testing is seen as crucial to tracking and tackling the disease.
While theoretically simple for people to administer, the tests are quite complex. They would require that blood that a test-taker donated before the epidemic be available to detect false positives that might come from the antibodies of other types of coronavirus.
