How does Test To Return work?

Order your Chronomics Test To Return kit as soon as you are able to - ideally when first making your travel plans to the UK.  Up to 72 hours before you’re scheduled to fly to the UK, you’ll make a short video call to one of our trained healthcare professionals who’ll guide you through the process, step by step. Easy!

Step 1: Buy before your trip

Buy your test online. We advise placing the order at least a week before you’re due to leave the US or the UK.

Step 2: Get ready to fly and register

Within 72 hours of your scheduled flight, follow the simple and intuitive instructions in the kit to register the test online and arrange for one of our friendly healthcare professionals to call you back using the video call platform of your choice.

Step 3: Take the test

Following the professional’s advice, take the test using the swabs and the lateral flow device provided. It should only take a few minutes to do this.

Step 4: Get your result

Our Test To Return kits usually give you a result in just a few minutes. Once you’ve got one, confirm it with us and we’ll automatically generate a certificate to travel in your Chronomics online dashboard.

Step 5: Connected tech

You can seamlessly link your Chronomics travel documents to third-party verification apps, health passports and more (such as IBM Digital Health Pass and Verifly) using our best-in-class technology and connected partnerships.

Step 6: Travel to the UK

Get packing and head to the airport, safe in the knowledge your Chronomics dashboard will let you view and download everything you need to board the plane. Enjoy your journey!
