Before booking a ‘fit to fly’ COVID-19 test
Although the turnaround times on tests can be very fast, you need to make sure you can get an appointment. Depending on demand, it can be difficult to book a test at short notice. If you have time, book a week or more in advance to be safe.
Many clinics will have experience with requirements for certain destinations, you must check the specific requirements that you will need need to enter a country and/or board the plane with the relevant embassy and airline.
You can legally travel to medical appointments in the UK during the lockdown. People using public transport must observe the latest safety guidelines (wearing a mask, etc.).
You’re not allowed to use the NHS testing service for ‘fit for travel” COVID tests. Plus, they may not be sufficient for the border requirements at the destination country anyway.
Check the UK foreign office guidance on foreign travel. Current guidelines states you need to arrange a private test for travel.

Clinic checklist: Things to confirm before you book a test
- Does the lab/clinic have the correct accreditation for your requirements (usually UKAS)?
- Do you need an original copy? Many labs give you results digitally only.
- Do you need additional custom forms/information? Some clinics are able to accommodate custom requests.

What types of COVID-19 tests are there?
Nasopharyngeal – This test is where they stick a long swab up your nose. It’s not as bad as it sounds, but may make your eyes water. This test may also include a throat swab. This is the original and most common sampling method for PCR testing in the UK.
Throat swab only – Some places only take throat swab samples. This is a lot easier on the patient, but note it may not be sufficient for some destination countries with rigorous standards (like Japan).
Saliva – This test is where you spit into a tube for the newer rapid LAMP tests (like the 1-hour test at Heathrow Airport).
