With the approval of it, Canadian laboratories will use the DiaSorin LIAISON to detect antibodies that are specific to COVID-19 in hopes of learning more about immunity.

Scientists are getting closer all the time to finding a vaccine for the coronavirus, but why are antibodies so important?

Initially only patients in hospital could get tests in the UK.

The Department of Health and Social Care says it is working on plans to roll out the test to the wider public and will make further announcements.

Thank you for your feedback.

"Some of the tests didn't perform very well", she said.

Kleine said Roche had also received Emergency Use Authorization from the US Food and Drug Administration on May 2. "We are very keen to get that test on stream as swiftly as we can", he added, calling it a potential "game-changer".

"The level of immunity that gives you is still being scientifically debates but it looks like it does give you a level of immunity".

"Serological testing will contribute to a better understanding of whether people who have been infected by COVID-19 are immune to the virus", the statement read.

There has been some suggestion that immunity could last for two to three years but more work needs to be done.

Massive Chinese rocket falls back to Earth, largest in decades
The Long March 5B rocket in question was launched from the Wenchang Space Launch Center carrying an unmanned prototype spacecraft. The launch proceeded normally and represented another success for China as it seeks to build a robust human spaceflight program.

The idea of an antibody test with 100 percent accuracy was previously labeled by Prime Minister Boris Johnson as a "game-changer" as it would allow the government to understand how many people had COVID-19 and if they had developed immunity.

That will also help inform public health decisions.

Health Secretary Matt Hancock last week said the United Kingdom was in talks with Roche about a "very large-scale roll-out" of coronavirus antibody testing.

A new antibody test to determine whether people have ever been infected with coronavirus is 100 per cent accurate, according to Public Health England (PHE).

It will work on blood samples taken by a healthcare professional at least 14 days after a person develops Covid-19.

"Hospitals and reference laboratories can run the test on fully-automated equipment already widely installed by Roche Diagnostics at sites across the United Kingdom with results provided in 18 minutes".

Prof John Newton, the national coordinator of the United Kingdom coronavirus testing programme, told the Telegraph experts at PHE's Porton Down labs had evaluated the test and confirmed the 100% accuracy.

"This is a very positive development because such a highly specific antibody test is a very reliable marker of past infection", UK's coronavirus testing programme coordinator John Newton said.

"This in turn may indicate some immunity to future infection, although the extent to which the presence of antibodies indicates immunity remains unclear".

It could pave the way for many more people to return to work if they know they have had the virus.
