How it works

Antigen Lateral Flow Fit to Fly kits – for use before you leave the UK, subject to receiving a negative result, you will receive a Fit to Fly certificate.

This is not a supervised service, please ensure that an unsupervised self-swab is acceptable for the country you are travelling to.


To submit your completed test you can use our ExpressTest web form via a mobile device or PC. You will need to upload photos of your completed test cassette and ID.

You can submit your results at any point from 15 minutes (after dropping your sample on to the cassette) but for the clearest results we recommend submitting after 25-30mins.

You will receive your verified results via email within 2 hours of submitting your results (within our hours of operation 0800 - 2359 UK time 7 days a week).

Before you begin

  • Ensure you have a working internet connection 
  • You must have your passport to hand.
  • If you are testing on a child under 12, or a person who requires assistance, ensure they are sitting still and follow the steps set out below.

Step by Step guide / collecting your sample / submitting your results

Step by Step guide / collecting your sample / submitting your results

Step 1. Ensure you have a working internet connection

Step 2. It’s now time to take your antigen lateral flow test. Place the buffer tube into the hole on the top of the box before starting the swabbing process.

Step 3. Remove the swab from the packaging; do not touch the cotton end. NOTE: Those under 18 should be swabbed by an adult.

Step 4. Insert the cotton end of the swab gently into one nostril until you feel resistance (about 2.5cm, 1 inch). Slowly rotate the swab 5 times, brushing against the side of the nostril before removing the swab and repeating in the other nostril. NOTE: Remove all piercings before swabbing.

Step 5. Insert the swab into the buffer tube and swirl for 30 seconds before squeezing the sides of the tube and rotating the swab 5 times. Continue squeezing the tube while removing the swab.

Step 6. Attach the dropper tip firmly onto the buffer tube.

Step 7. Remove the test cassette from the sealed pouch and lay it on a flat surface. Hold the buffer tube vertically and deposit 4 drops into the sample well marked ‘S‘. NOTE: We recommend not reporting results later than 30 minutes after test completion; the longer the sample develops, the greater the possibility of a false positive result.

Step 8. Place the buffer tube and the swab into the waste bag and dispose of it with general waste.

Step 9. After 25 minutes, as shown in the app timer, follow the instructions to photograph your cassette and identification document.

Step 10. Your verified results will be emailed to you within 2 hours of submission, during our UK hours of operation from 08:00 – 23:59 GMT.
