'Game changer' coronavirus test to reveal who has had the disease with no symptoms
Video report by ITV News Health Correspondent Emily Morgan
A coronavirus test which reveals who has had Covid-19 but not shown symptoms has been hailed as a "game-changer".
The Government’s chief scientific adviser Sir Patrick Vallance said Public Health England’s (PHE) work on the antibody test is "progressing very fast", and will provide valuable insight into the pandemic.
Speaking at the daily Downing Street press conference, Prime Minister Boris Johnson said development of the test was not far away.

"The great thing about having a test to see whether you’ve had it enough, is suddenly a green light goes on above your head and you can go back to work safe and confident in the knowledge that you are most unlikely to get it again," the Prime Minister.
"So for an economic point of view, from a social point of view, it really could be a game-changer."
Mr Johnson added: "You can really see the potential of that advance, which, as I say, is coming down the track."
ITV News Health Correspondent Emily Morgan explains what she's hearing from health workers on the frontline:
Sir Patrick added: "That’s progressing very fast, Public Health England are looking at this today.
"They’ve got a test in house they’ve got going and we’re looking at ways at getting the much more widespread version out.
"It is a game-changer.
"And the reason it’s a game-changer is that it allows you to understand the proportion of the asymptomatic population – who’s had this disease, but hasn’t had symptoms.

"Going forward it’s going to be critically important to be able to monitor this disease well because only by being able to monitor it can we start relaxing measures again."
Earlier on Wednesday, the Government announced that it would be ramping up its testing efforts, carrying out 25,000 coronavirus tests per day.
On Tuesday, head of the World Health Organization, Dr Tedros Adhanom Ghebreyesus said one of the best ways to beat Covid-19 is to "test, test, test" people.
Speaking at Government's daily press conference, Dr Jenny Harries, deputy chief medical officer for England, said officials were also looking at Covid-19 tests that could be taken at home.
She explained: "As we go forward, we have an ambition to have some sort of home-based test for the very reason which has been described here – which is we don’t want potentially infectious people arriving in hospitals.
"But we recognise that the public, and particularly our key workers, want to understand their status so that they can get back to normal activities."
She added that a lot of work was ongoing in that regard and "huge" progress had been made in the last few weeks.
