Two members of the Royal Statistical Society say UK government’s figures rely on spiked lab tests and not real world tests
Saliva tests for Covid-19, which are being introduced for NHS workers as part of the government’s mass testing programme, pick up only 13% of people with low levels of the virus and not 91%, as the official assessment has claimed, according to experts.
Two members of the Royal Statistical Society’s working group looking at the accuracy of Covid tests have questioned the results and the way they have been evaluated.
