Health officials in England have approved a new antibody test to find if someone has been infected with coronavirus in the past. It was developed by the Swiss pharma company Roche, which involves a blood test that scans for antibodies to see if a person has already had the virus & might have some immunity. British PM Boris Johnson has earlier told that such an antibody test will be a game-changer in this fight against the virus.
