Educational only — not legal advice.

What it shows

A tuberculosis (TB) test certificate comes from an approved clinic after a chest x-ray. It is needed when you are coming to the UK for 6 months or more and have lived for 6 months or more in a country on GOV.UK's list within the last 6 months. The certificate is valid for 6 months from the date of the x-ray.

Strong vs. weak

Strong

From an approved clinic, with your name and passport number
Shows the x-ray date and is still valid on the day you apply
Passport number matches the passport you submit

Weak

A test from a clinic that is not approved
A certificate that will have expired by the application date
A name or passport number that differs from the application

How to prepare it

Check GOV.UK's list of countries to see whether you need a test
Book the test with an approved clinic, and time it so the certificate is still valid on the day you apply
Check the name and passport number on the certificate against your passport

Common mistake

Taking the test too early, so the certificate has expired by the time the application is made.
