🧬 What is Immigration DNA Testing and When is it Used?
Immigration DNA testing is a scientifically reliable method used to prove biological relationships for UK immigration and passport applications—especially when other forms of documentation are missing, insufficient, or disputed.
While not mandatory, DNA evidence can significantly strengthen an immigration case when submitted voluntarily, and is often recommended by legal representatives or caseworkers.
📌 When is Immigration DNA Testing Typically Used?
1. To Establish Biological Relationships
DNA testing is most commonly used to confirm:
Paternity or maternity
Sibling relationships
Grandparent and grandchild connections
Other complex familial relationships (e.g. uncle/niece, aunt/nephew, cousins)
2. To Support Immigration or Passport Applications
DNA testing is particularly useful when:
Birth certificates or marriage documents are unavailable
Official documents are considered unreliable or unverifiable
Additional evidence is needed to confirm eligibility for family visas or citizenship
3. For Family Visas and UK Passports
Testing is often used in applications for:
Family reunion visas (e.g. spouse, fiancé, dependent children)
UK passports for children born abroad
Appeals where biological connection is central to the outcome
✅ Key Considerations for Immigration DNA Testing
Voluntary Submission
The Home Office cannot require DNA testing, but it may suggest it as an option. Applicants can choose to submit DNA evidence to support their case.
UKAS-Accredited Laboratories Only
For DNA results to be accepted by the Home Office, UKVI, HM Passport Office, or UK courts, the test must be performed by a UKAS ISO 17025-accredited laboratory.
Independent Sample Collection
DNA samples must be collected by an independent professional, following strict chain of custody rules as per Home Office guidance. This ensures:
Verified identity (with photographic ID)
Witnessed consent
Tamper-proof handling of samples
Consent Requirements
Individuals aged 16 and over must give written consent.
For those under 16, consent must come from someone with parental responsibility.
Part of a Broader Evidence Package
DNA test results are treated as one piece of supporting evidence and should be submitted along with other documents such as:
Application forms
Passports or visas
Letters from legal representatives
Statements of circumstance
🧪 How is a DNA test useful for immigration applications?
DNA tests become invaluable when:
Official documents are unavailable or forged
Multiple children require proof of direct parentage
Caseworkers request independent evidence to avoid fraud
By using up to 25 genetic markers, Greenplace Healthcare offers stronger statistical certainty than the industry standard greenplacehealthcare.co.uk.
⚖️ What legal requirements must labs meet?
To be accepted by UK authorities, DNA testing must be performed by a UKAS ISO 17025‑accredited laboratory following the Home Office chain‑of‑custody protocol. Greenplace Healthcare and our UK partner lab meet all standards set by:
UK Home Office
UK Visas & Immigration (UKVI)
HM Passport Office
Immigration Enforcement, Border Force, Ministry of Justice
