A Tuberculosis (TB) test is a mandatory requirement for many UK visa applicants. Whether you need one depends on where you have lived, how long you plan to stay in the UK, and the type of visa you are applying for. Failing to understand this requirement can result in delays or outright refusal of your application.
Below is a detailed guide on who needs a TB test, the exemptions, and the testing process.
When is a tuberculosis (tb) test required?
The UK government requires TB screening for visa applicants from countries where tuberculosis is more prevalent. A valid TB certificate must be provided with your visa application if applicable.
The official list of countries is published and updated on the UK government website.
TB test requirements for adults
You will need a TB test if all of the following apply:
-
You have lived in a listed country for at least six consecutive months
-
You are applying to stay in the UK for longer than six months
-
You have been present in a listed country at any point within the six months before your application, even if you recently moved to a low-risk country
The 6-month residency nuance
If you recently relocated from a “high-risk” country (for example, India) to a “low-risk” country (like the USA) but have not spent six months in the low-risk country yet, you still need a TB test from your previous residence.
Additional adult visa categories
Even if you lived in a listed country for less than six months, a TB test is still required if you are applying for:
-
A Returning Resident visa
-
A Family visa, including fiancé, fiancée, or proposed civil partner
British National (Overseas) visa applicants
BNO applicants already in the UK may need a TB test only if they did not provide a certificate when entering (for example, entering first on a 6-month visitor visa). If you have already been in the UK for more than six months on another visa, a new TB test is usually not required for an extension.
TB test requirements for children
All children must attend a UK government-approved clinic. A health questionnaire must be completed on the child’s behalf, and the clinician will determine whether testing is necessary.
If the clinician confirms no TB is present, a certificate is issued and must be included with the child’s visa application.
TB testing during pregnancy
Pregnant applicants may choose to delay the TB test until after delivery. If testing during pregnancy is necessary, two options are available. A chest X-ray can be done safely with additional protective shielding for the mother and baby.
TB test exemptions
You do not need a TB test if you are:
-
Applying under a UK scheme supporting people from Ukraine
-
A returning UK resident who has been outside the UK for less than two years
-
A diplomat accredited to the UK
Note: For applicants from Ukraine applying under other visa categories, a TB test may still be required if they have been residing in Ukraine.
Why does the UK require a tb test?
The TB test is a public health measure. Countries with higher TB prevalence are identified by the UK government to reduce the risk of transmission within the UK.
A valid TB certificate ensures you do not have active TB at the time of application.
How long is a tb certificate valid?
A TB test certificate is valid for six months from the date of issue.
Some applicants may be asked to undergo additional screening after arrival to detect latent TB, which helps prevent reactivation in the future.
What happens if you test positive for tb?
If your TB test result is positive, you must complete treatment before submitting your UK visa application. Visa applications cannot be approved without a valid TB certificate confirming successful treatment.
The sputum trap: inconclusive X-rays
If your chest X-ray shows any shadows or abnormalities, even from old or healed lung injuries, a sputum culture test is legally required.
-
Timeline: Results take 8 to 10 weeks.
-
Applicants with previous lung scarring may face delays, even if they are healthy.
-
Advice: Book TB appointments at least three months before your intended travel date to avoid delays.

The tuberculosis (tb) test process
where the test must be taken
TB tests must be completed before entering the UK at an approved clinic. Tests taken at non-approved clinics are not accepted.
If no clinic is available in your country, you may need to travel to a neighbouring country.
What happens during the test
For adults and children over 11, the TB test is usually a chest X-ray.
-
If results are unclear, a sputum culture test is required.
-
Pregnant applicants can choose their preferred method, with shielding provided for X-rays.
Tuberculosis (tb) test costs
Clinic fees vary and are set by individual clinics, not the UK Home Office. Always check with your local approved clinic for accurate costs.
