The words: How Long Is the UK TB Test Valid For? with a UK flag, stethoscope and a medical chart.

The UK TB Test is a prerequisite for international students who want to work and study in the United Kingdom.

The tuberculosis (TB) test certificate simply shows whether you are safe to enter the country. If your test result shows that you do not have tuberculosis, your visa approval rate increases. However, the test is valid for only 6 months, and it must still be valid before you start your visa application.

Submitting an expired TB test or certificate can lead to the outright rejection of your visa. While the certificate needs to be valid before your visa, it does not necessarily have to be when it’s time to travel.

In this guide, we will explain how long the UK TB test is valid, who needs it, when to take it, and how to avoid common mistakes.

What Is the UK TB Test?

The UK TB test is a medical screening required by the UK government for international students and visa applicants who want to work and study in the country for extended periods. The TB test certificate is used to check whether an individual has active tuberculosis, which is a contagious infection that mainly affects the lungs.

The individual must undergo chest X-rays from a reputable hospital or clinic before it can be accepted. If your test result is clear, you will receive a TB test certificate from the clinic. This will then be included when applying for your visa.

How Long Is the UK TB Test Valid For?

The UK TB test certificate is valid for 6 months from the date of issue. For individuals whose family has a history of the disease or who have been in close contact with anyone who has TB but do not have it themselves, they will only get a certificate valid for 3 months.

The test must be conducted in a UKVI-approved clinic in your region, and the original certificate must be submitted when applying for your visa.

If you have tuberculosis, you cannot get a TB certificate, and that automatically becomes the grounds to disapprove your visa. What you should do is take your treatments seriously, and when you are healthy again, you can do the test to get a clean certificate for your application.

When Should You Take the TB Test?

If you are applying for a visa to study or work in the UK, you should plan to take your TB test close to when you will submit your documents for the application. For instance, if you are planning to start your visa application in June, you can take your test 1 to 3 months earlier.

This will ensure that your certificate remains valid until your visa application is successful. Timing is very important when taking your test.

Common Mistake to Avoid When Taking Your UK TB Test

  • Taking the test too early and applying several months after.
  • Taking your TB test in a clinic or health facility not approved by the UK VI.
  • Not submitting the certificate in the required format.
  • Applying with an expired TB certificate.
  • Submitting a TB test certificate with wrong or different information from your passport and other documents.

Who Needs a UK TB Test?

Not everyone visiting the UK needs to take and submit a TB test during their visa application. If you are staying in the UK for a short time, under 6 months, you may not necessarily need it. Children under the age of 11 years, returning UK residents, and pregnant women may also be exempt from submitting the certificate.

However, international students and those who want to work and live in the UK for more than 6 months must submit a valid TB test certificate with their visa application. Also, if you live in a country listed by the UK Home Office as requiring TB screening, you have to submit one. Always check the official UK visa guidelines to confirm your eligibility.

How Much Does the UK TB Test Cost?

The cost of a UK TB test ranges from £50–£100 and may vary depending on your country and local currency. Before taking the test, always confirm the exact cost with the approved clinic in your country.
