An antibody or serological test is used in the detection in ascertaining if an individual has contracted the Covid-19 virus previously and can also detect if the person in question has subsequently recovered.

The fifteen minute test involves a finger-prick procedure with the blood quickly analysed to determine if coronavirus antibodies have been generated thus gaining a higher level of immunity to future infection.

UK based daily The Telegraph maintain that the British government have purchased over three million of these finger-prick tests and with the tests set to be available for purchase in the future via Amazon and the Boots chain with an expected retail price of approximately seven euro.

Hancock advocates social distancing

Speaking ion the BBC last week, UK Secretary of State for Health and Social Care, Matt Hancock told BBC’s Today Programme: “The antibody tests are important as scientists say they are more important later as we are trying to come out of the extraordinary social distancing measures, the lockdown, because it is on the way out that you then know how many people have the immunity. At the moment, the most important thing for getting out of this as soon as possible is for people to follow the social distancing rules.”
