Twice-weekly testing for covid is one of the measures that will help to protect against the spread of coronavirus in the community.
If you are working, going to school or college, or generally getting out and about and meeting other people, then testing twice a week will help to protect you and your friends, family and colleagues.
Lateral flow tests are free. They can be collected from pharmacies or delivered directly to you by post. More information from the NHS – see this link: https://www.nhs.uk/conditions/coronavirus-covid-19/testing/regular-rapid-coronavirus-tests-if-you-do-not-have-symptoms/
