Today-Dec 8

A team of researchers has developed a quick and fairly accurate way of detecting for Covid-19 using an individual’s saliva. Clinical trials found that its accuracy in terms of correctly identifying those infected with Covid-19 was only slightly lower than a polymerase chain reaction test.  However, it was somewhat less accurate in identifying those who were not infected. The latest testing method differs from conventional saliva-based antigen rapid tests in that it can be used at any time of the day. The researchers hope to have it commercially available within three to six months. A simpler, less invasive way to test for Covid-19 quickly that is close to the accuracy of a polymerase chain reaction (PCR) test in terms of correctly identifying infected individuals has been developed by scientists in Singapore. The test requires only an individual’s saliva, rather than a throat or nasal swab. It is somewhat less accurate than a PCR test in terms of correctly identifying those who do not have the virus. They said the test, which can be self-administered and is anticipated to have a low cost, had outperformed existing antigen rapid tests (ARTs) in early clinical testing and is “potentially game-changing”.
