No more anal probes? Non-invasive skin swabs are enough to quickly detect Covid-19, new study finds

In a breakthrough that will be welcomed across the globe, University of Surrey researchers claim to have developed a highly accurate Covid-19 test using non-invasive skin swab samples. Much of the world population who have undergone Covid-19 tests have likely experienced the rather unpleasant polymerase chain reaction (PCR) test, which, as many recipients attest, feels like the equivalent to having your brains scrambled like an egg or ‘stabbed’ given how far back in the throat and down the nose the swab must go. No penetration of the brain occurs in reality, however. Authorities in China took things a few steps further and anally swabbed over one million Beijing residents for the more infectious UK variant of the coronavirus, insisting that the highly invasive method was more accurate than PCR tests. In a new paper published by The Lancet’s E Clinical Medicine, the researchers took sebum samples from 67 hospitalized patients, 30 of whom had tested positive for Covid-19 and 37 who…
