Good Morning Britain 's resident expert Dr Hilary Jones says the new coronavirus antibody test approved for the UK may not confirm immunity from the virus.
The GMB doctor made the comments after it was claimed the new antibody test has been found to be 100% accurate, according to public health leaders.
Talking about the test, Dr Hilary told hosts Piers Morgan and Susanna Reid : "It doesn't necessarily tell you you're immune, or for how long - that's a big difference. "I think a lot of people are jumping to the conclusion that 'Oh have an antibody test, you've had the virus, you're fine to go back to work, everything's hunky dory for the next 10/20 years.' "We don't know that." Piers then interjected, adding: "They're hopeful apparently,"
