Covid lateral flow tests only pick up 49 per cent of infections because they fail to catch people carrying low level of the virus, researchers believe - blowing a massive hole in Government's mass testing strategy
Coronavirus lateral flow tests only pick up 49 per cent of infections because they fail to catch people with low levels of the virus, researchers have found. The findings of a pilot of 3,199 people has blown a hole in the Government's mass testing strategy, which featured plans to hand out millions of 30-minute tests to allow Britons to go back to living life normally, it was revealed yesterday. The lateral flow test produced by US-based Innova only pick up 48.89 per cent of active infections, according to a University of Liverpool pilot programme. It contradicts earlier lab tests, which found the test had an overall sensitivity of 76.8 per cent, rising to 95 per cent in individuals with a high viral load. The findings of a pilot of 3,199 people has blown a hole in the Government's mass testing strategy, which featured plans to hand out millions of 30-minute tests to allow Britons to go back to living life normally.
