IN THE UK, essential workers are now among those being sent home testing kits for coronavirus. This involves swabbing the inside of your own nose and the back of your throat, but how useful are the results?

This has prompted claims that self-testing will give even more false negatives and could raise the risk of infected people spreading the virus.
