UK Visa Medical Test Requirements 2026: TB Screening and Health Checks

United Kingdom visa medical requirements in 2026 are dominated by a single mandatory test: the tuberculosis (TB) screening that applicants from 101 high-risk countries must complete before applying for any visa permitting a UK stay of 6 months or longer, per gov.uk/tb-test-visa. The test must be performed at a Home Office-approved clinic, with the International Organization for Migration (IOM) operating in many high-risk countries and a network of private clinics covering the rest. The certificate is valid for 6 months from the test date, with fees ranging from £50 to £150 depending on country and clinic. Most other UK visa routes do not require a general medical examination, with the partial exception of the discontinued NHS Health Visa equivalents, certain Home Office-Health Visa hybrids for specific public sector recruitment programmes, and the standard right-to-work health check undertaken by employers separately. A positive TB result triggers further investigation including chest X-ray review by a UK Border Force-approved radiologist, sputum culture, and onward referral to a specialist; serious active TB can lead to visa refusal, with the application held until treatment is complete or alternative arrangements are made. Applicants from non-listed countries do not need the TB test, including travellers from most EU countries, North America, Australia, New Zealand, Japan, and most of South America.

Who needs a TB test?

Applicants who are nationals of, or have lived for 6 or more consecutive months in, a country on the Home Office TB-listed countries list and who are applying for a UK visa permitting a stay of 6 months or longer must complete the TB test before submitting their visa application, per gov.uk/tb-test-visa. The list contains 101 countries with high TB prevalence, including most of South Asia, Sub-Saharan Africa, Southeast Asia, Eastern Europe (excluding most EU members), and parts of Latin America and the former Soviet Union.

Applicants applying from a non-listed country who have lived in a listed country for less than 6 months in the previous 6 months do not need the test. Applicants applying for short visit visas (under 6 months) do not need the test regardless of country. UK-based applicants extending or switching visas inside the UK do not need a fresh TB test, on the basis they have already been admitted past the original health screening.

How does the test work?

The standard test is a chest X-ray performed at a Home Office-approved clinic, typically operated by the International Organization for Migration (IOM) or a partner provider. The radiologist reviews the image for signs of active TB and issues a certificate of clearance where the X-ray is normal, per the Home Office service guidance on gov.uk.

If the X-ray suggests possible TB, the applicant proceeds to sputum sample analysis (microscopy and culture), which takes up to 8 weeks for full culture results. Children under 11 and pregnant women receive a tailored assessment that does not require X-ray. The certificate is presented as part of the supporting documents pack at the visa application centre.

What does the test cost?

Test fees are set by the approved clinic and vary by country, typically running £50 to £150 in equivalent local currency, per the IOM and partner clinic fee schedules. Higher-cost markets include the Gulf states and South Africa; lower-cost markets include Bangladesh, Pakistan, and Nepal. Fees cover the X-ray, radiologist review, and certificate issuance.

Sputum testing where required adds to the cost and takes longer, typically £30 to £80 in additional fees and 4 to 8 weeks for results. Applicants should book the test 6 to 8 weeks ahead of their planned visa application to allow for any sputum follow-up, and check the clinic's accepted payment methods (cash, card, online portal) before attending.

What if the test is positive?

A positive screening result triggers further investigation including a follow-up X-ray, full clinical examination, and sputum culture for definitive diagnosis. Active pulmonary TB can lead to visa refusal until treatment is completed and the applicant is non-infectious, per Home Office and Public Health England (now UKHSA) joint policy on gov.uk.

Treatment typically runs 6 months for drug-sensitive TB and longer for drug-resistant variants. The applicant can reapply for the visa with a fresh TB clearance certificate after treatment is complete and a non-infectious status is confirmed by the treating physician. Latent TB without active disease does not bar the visa but is recorded on the certificate for follow-up by NHS services after arrival.

How does the TB test compare to other visa medicals globally?

The UK runs a more targeted regime than most major immigration destinations, focusing only on TB screening and only for nationals or residents of the 101 listed high-risk countries. Most other countries with significant inbound migration require a broader medical panel that includes blood tests, vaccination history, and general physical examination.

What about NHS Health Visas?

The NHS Health Visa hybrid (which combined immigration approval with NHS health checks for some hospital recruitment programmes) was largely discontinued in 2022 alongside the main Tier 2 reforms, with NHS-recruited Skilled Workers now subject only to standard right-to-work and TB-test rules. Specific NHS occupational health checks performed at the start of NHS employment are HR processes separate from the immigration framework.

The Immigration Health Surcharge of £1,035 per year for adults and £776 per year for students and under-18s gives access to NHS services on the same basis as UK residents, paid up-front at visa application. The IHS is separate from any TB test fees and is the principal NHS-related cost in the UK visa application framework.

What public health data is published?

The UK Health Security Agency (UKHSA) publishes annual TB notifications data on gov.uk, with breakdowns by region, age, and country of birth. Pre-entry TB screening has been credited with substantial reductions in active TB notifications among new arrivals since the regime expanded in 2014, though some active cases continue to present after arrival due to latent TB activation.

The Home Office does not separately publish TB test pass and fail rates, but FOI releases and academic studies including those from the London School of Hygiene and Tropical Medicine (LSHTM) on lshtm.ac.uk have analysed the screening programme. Independent commentary from the British Thoracic Society on brit-thoracic.org.uk provides clinical context for applicants and clinicians.

The pre-entry TB screening programme was expanded significantly in 2012-2014 to cover the current list of 101 countries, replacing a narrower on-arrival screening regime at ports of entry that had historically missed a material share of latent and early-active cases. LSHTM research published in The Lancet Public Health and elsewhere has credited the pre-entry approach with higher detection yield and better onward treatment linkage, because certificates are issued before travel rather than under time pressure at a port arrival. NHS primary care registers continue to pick up latent TB activation in the years after arrival, with Public Health England (now UKHSA) guidance on post-arrival screening for new residents from high-incidence countries supplementing the pre-entry certificate.

Frequently asked questions

Do I need a TB test for a tourist visa?

No. Visit visas under 6 months do not require the TB test, regardless of country. The 6-month threshold is the trigger.

How long does the certificate last?

6 months from the test date. The certificate must be valid at the date of visa application. If it expires before submission, a fresh test is required.

Can I use my own doctor?

No. The TB test must be done at a Home Office-approved clinic. Tests from non-approved providers are rejected. The list of approved clinics is on gov.uk/tb-test-visa.

What if I'm pregnant?

Pregnant applicants take a sputum culture rather than X-ray. The certificate is issued on the same basis once results are clear. Allow 4 to 8 weeks for sputum testing.

Are children tested?

Children under 11 receive a clinical examination without X-ray. Children aged 11 and over follow the standard adult protocol with chest X-ray.

Do EU citizens need the TB test?

Most EU countries are not on the listed 101, so EU citizens generally do not need the test. Romania and Bulgaria nationals should check the current list before applying.

Will the NHS retest me on arrival?

Not routinely. NHS GPs may flag latent TB findings during initial registration where indicated by the pre-entry certificate. Active disease found later is treated as a normal NHS clinical case.
