UK Visa Tuberculosis Test: Who Needs It and Where

Who needs a TB test

Visa applicants applying for stays of more than 6 months who have been resident in a listed country for the past 6 months or more must complete the test. The list is published on GOV.UK and covers most of South Asia, Sub-Saharan Africa, parts of South-East Asia, and others.

Applicants who have been outside the listed country for less than 6 months are still required to test in most cases. Returning UK residents are exempt where they can show they have been continuously absent from listed countries for the relevant period.

Where to take the test

Tests must be taken at a Home Office-approved clinic in the country of residence (or where the applicant is currently based). The list of approved clinics is country-specific and published on GOV.UK. Tests at non-approved clinics are not accepted, even from reputable hospitals.

Costs vary by country and clinic. Appointments can typically be booked online or by phone and are usually completed within a few days. Children under 11 are not normally tested; the parents' tests are usually sufficient.

What the test involves

The standard test is a chest X-ray. If the X-ray is clear, the certificate is issued, typically on the day or within a few days. If the X-ray shows changes, follow-up testing (sputum tests) may be required, extending the process by several weeks.

Pregnant applicants typically have sputum testing without chest X-ray during pregnancy. Specific clinic guidance covers BCG vaccinated applicants and other medical considerations.

Using the certificate in the visa application

The TB certificate is uploaded with the online visa application. It must be valid (within 6 months of issue) at the date of application. If the validity expires before the visa is decided, retesting may be required at UKVI's discretion.

The certificate name and date of birth must match the applicant's passport. Discrepancies should be resolved before applying; clinics will reissue corrected certificates if the error was theirs.

Listed countries and the rationale

The Home Office publishes a list of countries from which applicants must complete a TB test before applying for UK visas of more than 6 months. The list is updated periodically as countries' TB epidemiology changes. The current list includes most of South Asia (India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan), much of Sub-Saharan Africa (Nigeria, Ghana, Kenya, Uganda, Tanzania, South Africa and many others), parts of South-East Asia (Thailand, Vietnam, Indonesia, the Philippines), and several others.

The rationale is public health: countries with higher TB incidence pose a higher residual risk of latent TB infection that could become active after migration. The pre-arrival screening reduces the burden on NHS TB services and supports public health surveillance. The Migration Advisory Committee and Public Health England (now UK Health Security Agency) have provided the analysis underlying the list.

The 6-month residency rule: applicants who have been resident in a listed country for the 6 months immediately before applying must test. Applicants who have been in a listed country only briefly (e.g. a 3-month rotation, short business trip) may not need to test, depending on the specifics. The Home Office's caseworker guidance covers the borderline cases.

Some applicants are exempt entirely: diplomats and their dependants on diplomatic missions, certain returning UK residents, children under 11, certain pregnant applicants (with separate guidance on sputum testing as alternatives to chest X-ray).

Where to take the test

Home Office-approved clinics are listed by country on GOV.UK. The list is country-specific; an approved clinic in one country is not an approved clinic for applicants from another country. Tests at non-approved clinics are not accepted, even from reputable hospitals or government health services. The approved clinic network varies in density: India and Pakistan have multiple clinics in major cities; some smaller countries have one or two clinics covering the whole country.

Booking: typically online through the clinic's website or by phone. Appointments are usually available within days; some clinics have longer waits during peak visa application seasons. Walk-in service is uncommon; most clinics require booking.

Costs vary by country and clinic. India: typically Rs 6,500-7,500 (around £65-75). Pakistan: typically PKR 12,000-15,000 (around £40-55). Nigeria: typically N 50,000-70,000 (around £30-50). The fee is set by the clinic. Some clinics offer family discounts where multiple family members test together.

Identification at the clinic: passport plus the visa application reference where applicable. The certificate is issued in the applicant's full name as on the passport; mismatches must be reconciled before applying.

The test procedure in detail

Initial chest X-ray: the standard first step. The X-ray takes 5-10 minutes; reading the results takes longer. Most clinics issue the certificate on the same day or within a few days if the X-ray is clear. The X-ray is digital and the file is stored by the clinic for the certificate validity period.

Where the X-ray shows changes: follow-up sputum tests are typically required. Sputum samples are collected on 3 consecutive mornings; testing for acid-fast bacilli and TB-specific molecular tests takes 1-2 weeks. If active TB is identified, treatment is required before the certificate can be issued; treatment typically lasts 6 months.

Pregnant applicants: chest X-ray during pregnancy is generally avoided. Sputum-based testing is used; the certificate can be issued without X-ray where the sputum tests are clear. Specific clinic guidance covers the procedure.

BCG vaccinated applicants: BCG vaccination produces specific X-ray changes that can complicate interpretation. Clinics with experience in BCG-vaccinated populations handle this routinely; the X-ray report addresses BCG-related changes specifically.

Children under 11: not normally required to be tested. The parents' tests are usually sufficient. Children 11 and over follow the same testing process as adults. Where a child has been treated for TB previously, the family should disclose this for the clinic to consider whether testing is appropriate.

Using the certificate in the visa application

The certificate is uploaded with the online visa application as a PDF or image file. The file must be legible; clinic-issued certificates are typically formatted to UKVI's requirements. Some clinics provide a digital file directly to the applicant by email after the test.

Certificate validity: 6 months from the test date. Applications must be submitted while the certificate is still valid. If processing takes longer than the validity and UKVI requests confirmation, retesting may be required.

Name match: the certificate must be in the same name as on the passport. Common variations (middle names included or omitted, alternate spellings) should be addressed by the clinic before the certificate is issued. Errors discovered after issue can be corrected by the clinic.

Date of birth match: the certificate must show the same date of birth as on the passport. Mismatches require reconciliation, typically by the clinic reissuing the certificate.

Multiple applicants: each adult applies separately with their own certificate. Children under 11 do not need certificates. Family applications submit each family member's documents in the same online application.

Refused certificates and active TB findings

Active TB diagnosed at testing: the applicant cannot be issued a certificate until treatment is complete and the disease is confirmed inactive. Treatment under WHO-standard TB protocols lasts 6 months; the certificate can typically be issued after the treatment period and confirmatory tests show clearance.

Visa applications during TB treatment: the application is typically held pending the certificate. Some applicants choose to defer the visa application until treatment is complete and certificate issued; others maintain the application with explanation. UKVI guidance covers the case.

Latent TB: distinct from active TB. The pre-arrival X-ray screening identifies active TB primarily; latent TB (the bacteria present but not causing disease) is detected by interferon-gamma release assays (IGRAs) rather than chest X-ray. NHS Public Health England guidance on post-arrival latent TB screening of new entrants covers the position.

Children with TB history: where a child has been treated for TB previously, the visa application should disclose this with medical documentation. The disclosure does not automatically defeat the application; the question is whether the child currently has active TB or any continued risk. Pediatric TB specialists can provide the supporting documentation.

After the test: certificate handling and edge cases

Certificate validity tracking: the 6-month validity from test date is firm. Plan the visa application within this window. Where processing extends beyond validity (rare but possible), UKVI typically holds the application until retesting; arrange the new test promptly.

Name match issues: where the certificate name does not match the passport name (different spelling, missing middle name, transliteration variations), the clinic typically reissues at no extra charge if reported within a short window. Discrepancies after issue can be resolved by clinic confirmation.

Previous TB diagnosis: where the applicant has been previously diagnosed and treated for TB, disclose this on the application with medical evidence. The Home Office's caseworker guidance covers the consideration of past TB; treated and cleared cases typically do not defeat the application.

Vaccination considerations: BCG vaccination produces specific findings on chest X-ray that clinics with experience in BCG-vaccinated populations interpret correctly. Where the applicant has had BCG, the clinic should be informed at booking.

Test result discrepancies: where the chest X-ray finds something unexpected, follow-up testing is standard. The clinic provides interim reports; the final certificate is issued only when active TB is excluded. Treated and cleared cases can be certified after sufficient time has passed.

Records of TB testing and clinic documentation

Document organisation: a structured folder system (physical or digital) for immigration documents reduces friction across the years of the visa. Categories: identity (passports, BRPs, eVisa records), employment (CoS, payslips, employer letters), finances (bank statements, tax returns), relationships (where applicable), education (where applicable), travel (boarding passes, hotel receipts).

Digital preservation: scan and back up all documents to secure cloud storage. Multiple backups (separate cloud, USB drive, family member's copy) protect against loss. Encryption is sensible for sensitive documents (tax records, financial statements).

Long-term retention: documents from the visa period are needed at extension, ILR, and potentially naturalisation. Keep documents for at least 6 years after the visa period; immigration records are often referenced years later.

Records during the qualifying period: from day one of the initial visa, track UK presence and absences for the eventual settlement calculation. Travel logs, employer travel records, and supporting evidence all build the documentary picture.

Long-term planning across the immigration journey

Long-term planning across the visa lifecycle: the journey from initial visa to ILR to British citizenship spans 6-8 years typically. Building the documentary record, maintaining lawful status, planning extensions and switches, and the eventual settlement application all benefit from a long-term view.

Career and family planning around immigration: visa requirements interact with career progression, education choices, family timing, and other life decisions. Where significant life events are planned, considering the immigration position is part of the planning.

Risk management: keep documents, maintain contact with UKVI through changes of address, comply with visa conditions, build a clean record. Issues that arise during the visa years are easier to address proactively than at the settlement application.

Backup routes: where the primary route encounters difficulties, alternative routes provide options. Skilled Worker holders can consider Global Talent, family route, Innovator Founder depending on circumstances. Long Residence (10 years) provides a backup settlement path.

Future return scenarios: where the applicant may return to the country of origin or move elsewhere, planning preserves options. Maintaining country-of-origin ties, financial records, and qualifications supports future flexibility.

Frequently asked questions

Do I need a TB test for a UK visa?

Yes if you are applying for a visa of more than 6 months and have been resident in a listed country (most of South Asia, Sub-Saharan Africa, parts of South-East Asia and others) for the past 6 months or longer. Visits of 6 months or less do not require the test. The full list of countries is on GOV.UK. Diplomats, certain returning UK residents, children under 11 and some others are exempt. The certificate must be from a Home Office-approved clinic in the country of residence.

How much does the UK TB test cost?

Costs vary by country and clinic. India typically Rs 6,500-7,500 (around £65-75); Pakistan typically PKR 12,000-15,000 (around £40-55); Nigeria typically N 50,000-70,000 (around £30-50); other countries have their own pricing. Each approved clinic sets its own fee. Some clinics offer family discounts where multiple family members test together. Total costs for a family of four can run to £150-£300 across the testing process.

How long is the TB certificate valid?

6 months from the date of the test. Applications must be submitted while the certificate is still valid. If UKVI processing takes longer than the validity period and additional confirmation is needed, retesting may be required at the clinic. Planning the test relative to the planned application date is sensible: testing within 2-3 months of the application gives margin for processing delays.

Do children need a TB test for UK visa?

Children under 11 are not normally required to be tested; the parents' tests are usually sufficient. Children aged 11 and over follow the same testing process as adults. Where a child has been previously treated for TB or has TB symptoms, the application should disclose this with medical documentation regardless of age. The clinic can advise on whether testing is appropriate in specific circumstances.

What happens if my TB test is positive?

A positive screening usually leads to sputum and further tests to distinguish active TB from latent infection. If active TB is diagnosed, treatment under WHO protocols is required (typically 6 months); the certificate can be issued after treatment is complete and confirmatory tests show clearance. The visa application is typically held pending the outcome. Some applicants defer the visa application until treatment and certification are complete; others maintain the application with explanation.
