In detail: COVID-19 tests for international travel
Last updated: 16 May 2021
Confused about testing? Here’s some handy information, based on the official guidance from the UK government’s (NHS; gov.uk) and US government’s respective health departments (CDC; FDA).
COVID-19 tests are available to test for current infection or past infection.
- A viral test tells you if you have a current infection. Travel restrictions often require a negative viral test to enter or leave a country.
- An antibody test might tell you if you had a past infection. Antibody tests should not be used to diagnose a current infection and are not part of common travel requirements.
The two main tests for travellers are:
- PCR tests – mainly for people with symptoms, they’re sent to a lab to be checked
- Antigen tests – only for people who do not have symptoms, they give a result in 30 minutes using a device similar to a pregnancy test

What tests do I need to enter/return to the UK?
To enter or return to the UK you will need to take one test 72 hours prior to departure and a minimum of one PCR test once in the UK. Specific requirements will be based on whether your origin country is classified as green, amber or red under the government traffic light system – see our guide here and the updated list here.
Pre-departure tests to allow you to arrive in the UK must meet strict standards, and you may not be fined £500 or stopped from entering the country if the test does not meet these standards. Unfortunately, it’s your responsibility to ensure you get the right test that meets the above requirements.

Where can I book a private test?
In the UK, if you’re not eligible for testing through a local NHS clinic or testing centre (check here), there are a number of places offering testing. Note that any tests available publicly (the free ones!) are only for domestic use and not for international travel which is why private testing is needed.
