New coronavirus antibody test found to have 100% accuracy, experts find



New coronavirus antibody test found

A new ‘game-changing’ and 100 per cent accurate coronavirus antibody 

test that can tell whether someone has had the bug has been approved 

forpublic use in the UK, public health bosses declared last night.


The test will identity everyone who has had COVID-19 with experts hopeful 

these people could be immune from catching it again for up to three years.



The Government is in talks with Roche, the Swiss pharmaceutical giant 

behind the test, to buy millions of the kits that could end the lockdown early.


Public Health England (PHE) announced scientific experts had carried out 

an independent evaluation of the antibody blood test at its top-secret 

Porton Down facility and found its results to be ‘highly specific’, identifying 

every sample from someone who had previously tested positive for 

coronavirus.

The findings have been hailed as a ‘very positive development’ in 

combating the coronavirus outbreak.


Scientists hope that those whose body developed antibodies after 

recovering from the virus could develop immunity for two or three years, 

making them safe to return to work. But the World Health Organisation has 

repeatedly cast doubt on whether people can become immune at all.


Professor John Newton, the national coordinator of the UK Coronavirus 

Testing Programme, said: ‘We were confident that good quality antibody 

tests would become available when they were needed.


‘This is a very positive development because such a highly specific 

antibody test is a very reliable marker of past infection. This, in turn, may 

indicate some immunity to future infection although the extent to which the 

presence of anti-bodies indicates immunity remains unclear.’


The test is designed to help determine if a patient has been exposed to the 

virus that causes Covid-19 and whether they have developed antibodies 

against it.


Antibody testing, as opposed to antigen tests which look for active viruses, 

will be key to reopening Britain. A 100 per cent accurate test would enable 

ministers to reconsider the idea of ‘immunity passports’ so people who 

have fought off the illness can return to work.


The passports have been mooted by countries across the world as part of 

the path out of lockdown, but plans were shelved pending a test accurate 

enough to rely on.


The news comes as Boris Johnson’s government considers the steps 

Britain must take to balance fighting the virus through lockdowns with 

economic damage that causes – which was yesterday said to be sparking a ‘
recession to end all recessions’.


The US Food and Drug Administration (FDA) has already issued an 

emergency use approval for the antibody test, called Elecsys Anti-SARS-

CoV-2.


Roche said in a statement late Wednesday it is in talks with National Health 

Service and the UK government about a phased roll-out of antibody test 

kits as soon as possible.
