Navigating the complexities of UK immigration requires precise documentation. When biological relationships must be proven to the Home Office, UK Visas and Immigration (UKVI), or the HM Passport Office, DNA evidence is often the final step to secure a visa or citizenship. At Brashan DNA Services, we provide the technical expertise and accredited results necessary to support your application.
How does the Home Office view DNA evidence?
The Home Office accepts DNA results only when the testing process meets specific legal standards. Do not use "peace of mind" home kits for immigration purposes; the authorities will reject them. You must use a laboratory accredited to ISO/IEC 17025 standards. This accreditation ensures the laboratory maintains technical competence and produces valid, reliable results.
Call us at +447360536054 to ensure your test meets these strict requirements.
Why is the "Chain of Custody" critical?
For a DNA test to be legally defensible, the identity of every participant must be verified. This process is known as the Chain of Custody.
- Appoint an independent witness: A trained professional must collect the samples. You cannot collect your own samples for an immigration case.
- Verify identity: Present valid photo ID (passport or driving license) at the time of collection.
- Capture photographic evidence: The sampler will take a passport-style photo of each participant to attach to the case file.
- Secure the samples: The collector seals the swabs in tamper-evident packaging and ships them directly to our accredited laboratory.

What samples are required?
We typically use buccal swabs (cheek swabs). This method is non-invasive and painless. Rub the swab against the inside of the cheek to collect skin cells. This process is highly effective and provides the necessary biological material for accurate profiling.
