Cochrane review says rapid antigen tests correctly identifies only 58% of asymptomatic people
Rapid lateral flow tests for Covid do not work well in people with no symptoms and should not on their own be used to allow people to go to work or school or travel, experts have said.
The UK has bought millions of rapid tests which give results within half an hour. Teachers, schoolchildren and their families without any symptoms are being asked to test themselves using the kits twice a week. “About one in three people with coronavirus do not have symptoms but can still pass it on to others,” says government guidance. “Regular testing of people without symptoms is important to help stop the virus spreading and protect your loved ones.”
