Unclear test result - Test to Release
Your coronavirus test result is unclear. It’s not possible to say if you had the virus when the test was done.
You must, by law, continue self isolating for the remainder of your self isolation period as an international arrival travelling to the UK from a non-exempt country, territory or region. You may be contacted to check that you are self isolating.
If you want to shorten your self isolation period you will need to take another test for international arrivals. For more information, go to https://www.gov.uk/guidance/coronavirus-covid-19-test-to-release-for-international-travel.
