4 Medical Testing: Test-To-Release (TTR) Certificate​ within 24 hours

Express TTR service: Results within 3 hours (ask the clinics for details).

The UK government requires ALL travellers arriving in England, MUST complete a Passenger Locator Form (https://www.gov.uk/provide-journey-contact-details-before-travel-uk).

However, any passengers arriving from Amber List countries (visit https://www.gov.uk/guidance/coronavirus-covid-19-travel-corridors#history for Amber List countries) can opt to have a COVID-19 test on day 5, and if the result is negative they can reduce the quarantine period. This scheme is called Test-To-Release (TTR).

You can book your TTR online as a home self-swab kit or clinic appointment at any time: before you leave UK or before arriving in the UK or when you arrive back at home. When ordering your TTR, please take care to enter your personal details as indicated in your passport, with correct postal address, and contact details.

4 Medical Testing will help you to shorten your quarantine period if your COVID-19 PCR test on day 5 is negative.

4 Medical Testing will send you a self-swabbing kit with easy to use instructions. Alternatively, your representative can attend one of our clinics (in London or Manchester: see below for 4 Medical Testing clinics addresses) to collect a self-swabbing kit. The kit will include clear and concise instructions to use, a sample swab, a collection tube, a safe transportation packaging, and a return postal packaging/envelope. Once you have self-swabbed, you can return the sample for analysis to 4 Medical Testing by either posting it via Royal Mail Priority Post Box (see www.royalmail.com/services-near-you to find your nearest priority post box and collection times) or alternatively, your representative can bring the sample in the package provided to 4 Medical Testing clinics for rapid processing and analysis.

Once receiving the sample, 4 Medical Testing will process immediately for a rapid turn-around of results within 24 hours (clinic ONLY). The test result will be available for you to either collect in person from the clinic or can be emailed to you in a PDF format which can be safely saved to your device (Smartphone, Tablet, Laptop or Desktop computers) for printing if a hard copy is required by your destination country’s immigration authority. The certificate will contain a valid TTR Code for Passenger Locator Form. Our aim is to help you shorten your quarantine time when possible!
