UK Visa TB Test Requirement 2026: Which Countries Need It

The UK visa tuberculosis test requirement is one of the oldest procedural hurdles in the immigration system, introduced under the 1971 Immigration Act public health powers and extensively updated across the 2010s to cover applicants from countries the World Health Organization classifies as high-incidence for active tuberculosis. The test is a chest X-ray, carried out at a UKVI-approved clinic published on the gov.uk country-specific page, and it applies to any visa of 6 months or longer for applicants who have been resident in a listed country for 6 or more months out of the past 6 months. The certificate remains valid for 6 months from the date of issue and must be within that window at the date of the visa application, not the date of decision. Getting the timing wrong, attending a non-approved clinic, or failing to disclose a prior positive result are each routes to refusal, and the process sits outside the normal application fee structure because the clinic charges are paid directly to the clinic, not to UKVI.

Who needs a TB test certificate?

An applicant needs a TB certificate where they are applying for a UK visa of 6 months or longer and have lived for 6 or more months in the past 6 months in a country on the TB test visa list, per the TB test for a UK visa guidance on gov.uk. The list covers roughly 100 countries across Asia, Africa, South America, and parts of Eastern Europe where WHO-notified incidence of active TB exceeds 40 cases per 100,000 population per year.

Residence is the test, not nationality. A Canadian national living in India for the past 12 months needs a TB test; an Indian national living in the US for the past 12 months does not. Transit spells of less than 6 months in a listed country during the 6-month lookback do not trigger the requirement, but applicants should keep evidence of travel history to rebut any UKVI query at entry clearance.

Which countries are on the list?

The list is published on gov.uk under "TB test for a UK visa" and includes all major South Asian countries, most of sub-Saharan Africa, Southeast Asia including Vietnam, Thailand, the Philippines, Indonesia, and Myanmar, and selected other states including Russia, Ukraine, Peru, and Bolivia. China, India, Pakistan, Bangladesh, Nigeria, Kenya, Ethiopia, and South Africa are all on the list, reflecting the WHO high-incidence classification.

The list is reviewed periodically by the Department of Health and Social Care in consultation with UKVI, though changes are infrequent. The current list reflects a last material update of April 2022. Applicants should check the live list on gov.uk at the time of applying, because additions or removals can shift the requirement without advance notice.

How do approved clinics work?

UKVI publishes a country-by-country list of approved clinics on gov.uk, including the International Organisation for Migration network and a small number of private providers authorised per market. Applicants must attend only an approved clinic; certificates from non-approved providers are rejected. Clinics are usually concentrated in capital cities and major hubs, and waiting times for appointments vary from same-day in small markets to 2 weeks in high-demand cities like Dhaka, Lagos, and Karachi.

The appointment takes about 30 minutes. The clinic reviews a health questionnaire, takes a chest X-ray, and issues a certificate within 1 to 5 working days depending on location, provided the X-ray is clear. Clinic fees range from roughly £50 in South Asia to £150 in parts of sub-Saharan Africa, paid in local currency direct to the clinic. UKVI does not refund or reimburse the fee even if the visa is later refused.

What if the result is positive?

A positive chest X-ray triggers a sputum test, which takes 8 weeks to complete because cultures must be grown and read. A confirmed active tuberculosis diagnosis means the applicant cannot be issued a TB certificate until they have completed treatment and been declared free of active TB by a clinician, per the gov.uk TB test positive result guidance.

Treatment usually lasts 6 months under the WHO-recommended four-drug regimen, followed by re-testing. Only a new certificate issued after treatment completion can support a UK visa application. Applicants with latent TB, where X-rays are clear but earlier infection markers are present, pass the UKVI test; latent TB is not a refusal ground.

Who is exempt from the test?

Applicants for Visitor visas, short-term study courses under 6 months, transit visas, and certain diplomatic categories are exempt regardless of residence history, per the TB test visa guidance on gov.uk. Children under 11 do not undergo X-ray but must complete a medical history review.

Pregnant applicants are offered a sputum-only alternative to avoid X-ray radiation exposure, with the test taking 8 weeks. UK-based applicants switching routes in-country do not need a TB certificate, because the residence trigger looks only at the 6 months preceding the current application.

How does timing interact with the application?

The 6-month certificate validity is measured from test date to application date, not decision date. A certificate tested on 1 May and used on a visa application submitted 29 October remains valid even if UKVI decides in November, because the application date falls within the validity window.

Frequently asked questions

Is the test required for a 6-month visit?

No. Visitor visas of up to 6 months are exempt regardless of country of residence, per the gov.uk TB test visa page. The requirement attaches only to visas of 6 months or longer.

Can I use a TB test from a private UK clinic?

No. UKVI accepts only certificates from approved clinics in the country of residence. A UK-based X-ray from a private clinic will not be accepted, and the test must be done before the visa application.

What if the approved clinic is in another city?

Applicants must travel to the approved clinic. UKVI does not add clinics to meet individual demand, and no alternative testing arrangement exists. Domestic travel costs to reach the clinic are the applicant's responsibility.

Does a prior positive BCG vaccination count?

BCG vaccination status is not relevant. The test screens for active pulmonary tuberculosis via chest X-ray, not immune response. BCG scars do not trigger any additional review.

Do children need the test?

Children aged 11 and above have the full chest X-ray. Children under 11 complete only a medical history review, per the gov.uk guidance. Any symptoms reported in the review trigger referral to a physician.

How much does the test typically cost?

Clinic fees vary by country, commonly between £50 and £150, paid in local currency. The fee is set by the clinic under its UKVI contract and is not refundable by UKVI.

What if I lose the certificate?

The issuing clinic can generally reissue a duplicate certificate on production of identification. Contact the clinic directly; UKVI does not hold certificate records.
