İrem GÖL -TDO- According to Guardian, a potentially “game-changing” spit for test for coronavirus is set to be trialled by the government on 5,000 police and army staff amid growing concern about the accuracy of invasive nasal swabs. The two-minute test requires someone to spit in a tube, and is thought to be as accurate, if not more so, than the throat and nose swab that detects if someone has Covid-19.
Prof. Paul Elliot, from the Imperial College London said he was very interested in the potential of the test because they are much easier to use. However, Elliot said that clinical experiences suggested that as many as 30% of nasal swab tests result in false negative, where people are wrongly told they do not have the virus.
The government trial will initially examine saliva antibody tests which - detect if someone has previously had Covid-19 – before being expanded to antigen tests showing current infections if it proves successful.
