A coronavirus antibody test said to be 99.8% accurate has been approved for use in the US, amid reports it could be available within weeks in the UK.
Roche Diagnostics' new serology test detects antibodies in patients who have been exposed to the virus that causes COVID-19, which could help to indicate if a person has gained immunity against the disease.
The Swiss firm says the test - called Elecsys - has a specificity greater than 99.8% and sensitivity of 100%, meaning it gives no false negative results and only one in 500 false positives.
And as the kits were approved for emergency use by the US Food and Drug Aministration (FDA), the company reportedly said it was "in dialogue" with the NHS and the UK government with a view to a "phased roll-out of the test from mid-May".
