Lateral flow tests for Covid work better than anyone thought, study finds | News



Lateral flow tests are more accurate at detecting coronavirus than previously thought and positive results should be trusted, researchers say.

A team led by University College London has developed a new formula to test the accuracy of lateral flow tests (LFTs).

The tests are probably more than 80 per cent effective at detecting any level of coronavirus infection and more than 90 per cent effective with those who are most infectious when using the test, according to their findings, published in the journal Clinical Epidemiology.

This level of accuracy is much higher than some previous studies have suggested and the authors say the tests are a reliable public health tool in stopping the spread of the virus. However, the research found that LFTs do
