‘None of the antibody tests were close’: UK’s coronavirus testing tsar says none of the kits assessed by the government work well enough to be rolled out across the nation – but he remains ‘optimistic’ of a breakthrough [LINK].

Professor John Newton has been tasked by Health Secretary Matt Hancock with overseeing the acceleration of Britain’s testing programme.

But he told MPs this afternoon that the government was yet to find an antibody test which is sufficiently accurate and that of the ones which have been examined ‘none of them performed well enough’.

He said experts had set a ‘clear target’ for the reliability of the tests but that of the devices assessed so far ‘none of them frankly were close’ to hitting it.
