The long wait for a coronavirus antibody test appears to be over after a version was given the go-ahead to be rolled out across the UK.

Developed by Swiss pharmaceutical company Roche, it was found to have a 100% accuracy rate by Public Health England (PHE).

The findings have been hailed as a “very positive development” in combating the coronavirus outbreak, as the test will determine if a patient has been exposed to the virus that causes Covid-19.

It will see if that person has developed antibodies against the disease, and can indicate if they have gained immunity against it.

It is different from the existing antigen tests used to simply check if someone currently has coronavirus.
