Share The UK government has added five more approved providers to its list of clinics able to carry out Covid tests as part of its test-to-release scheme, but another one of the providers on the initial list has withdrawn. The five new providers are: • Agilis Health, set up in June in Edinburgh, which offers remote and office-based tests; • Heathrow Medical Services, a provider of professional occupational health services and specialist medicals, now additionally offering Covid tests; • The London Clinic, based just off London’s Harley Street; • NPH Group, which offers testing services at Newcastle airport; • Randox, a large biotech firm based in Co Antrim, Northern Ireland.
