You’ll also might need to know:

  • If you need an outbound negative test to enter your destination country. If yes:
  1. what type do you need (a PCR or Rapid Antigen)
  2. how many hours in advance (eg. 48hrs or 72hrs)
  3. And is this based on your arrival or departure time?

If you're unsure about any of the guidance, please visit the UK's FCDO website to find out (for legal reasons, you'll have to check this yourself).

Chronomics is a UK government-approved testing provider. However, you are responsible for checking which tests are required by your destination country and selecting the correct package for your return to the UK.

Use our dropboxes for rapid results

We’ve introduced a new service for all Chronomics customers so you can get your PCR test results back even quicker (sometimes on the same day you drop off your sample)! You can use any of our rapid returns dropboxes in selected TUI stores across the UK – we’ll collect them and take them directly to our labs to be processed straight away.

Easy, accessible, fast

Returning your sample this way is easy – just perform your test and package up your sample as normal but, instead of going to a Royal Mail Priority Postbox, drop it at any one of our TUI locations instead. Just keep a note of your Kit ID – you’ll need it when you’re in-store. Click here for more details and step-by-step instructions on returning your sample this way.
