Antibody tests which will show if someone has had coronavirus have begun in Jersey.
Around 500 households have been selected at random and will have to visit one of three testing sites across the island.
Roughly 1,500 tests (from 500 households) will be taken every month to understand the spread of the coronavirus.
The Government hope this data will help them understand how and when to lift lockdown measures in a ‘careful, phased and controlled’ way.
The test will be carried out with a finger-prick using a drop of blood. Results will be ready within ten minutes.
Non-identifiable details will be shared with Statistics Jersey and made available to the public.
