Lateral Flow (Antigen) Fit to Fly Travel Test kits are pre-departure tests for fully vaccinated people leaving the UK or for use abroad ahead of your return journey to the UK if not fully vaccinated. 

We recommend that you purchase your tests at least 5 working days before your departing flight.

How to take Lateral Flow Test:

  1. Unpack the test kit and carefully read the instructions for use.
  2. Use a ball point pen to write your passenger locator number on the left hand side of the lateral flow device; ensuring that this number is clearly visible (see example here). IF YOU DO NOT WRITE THIS UNIQUE NUMBER ON THE LEFT HAND SIDE OF THE LATERAL FLOW DEVICE YOUR TEST WILL BE INVALID AND WE WILL NOT BE ABLE TO ISSUE YOU A CERTIFICATE.
  3. Undertake the testing procedure as per the test kit instructions.
  4. Enter your Passenger Locator No. as the unique serial number/Barcode on the activation page.
  5. Using your mobile phone, take a photo of your passport laid flat and open on the photo page alongside the lateral flow device within the boundaries of a plain white A4 paper; ensuring this photographic evidence complies with all the requirements as described in the instructions for use (see example here).
  6. Upload the photographic evidence to the activation webpage provided in your email link and complete all the details in the form. Please make sure you select FIT TO FLY USING LATERAL FLOW DEVICE under the pull-down option for type of test you want to perform; selecting any other will not allow you to attach photographic evidence. Submit your details once completed.
