A pharmaceutical giant is developing a coronavirus test to detect if people have already recovered from coronavirus that could be launched as soon as May.
Roche, the world's biggest biotech company, says it's "ramping up" production of new antibody tests and could be making tens of millions of the kits by June.
Antibody tests have been describe as a "game-changer" by the UK government, as they can detect whether the body has already fought off Covid-19 and developed an immunity.
The new test would send a blood sample to a lab, which would then produce a positive or negative results in as little as 18 minutes.
