Legal Siblingship DNA Test

 A legal DNA test is required for the following reasons: 

  • When providing legal information for immigration cases
  • Complex family reconstruction situations where one or more parents are able to be tested.

This DNA test requires a DNA sample to be taken by a professional doctor, nurse, or accredited sampler and cannot be self administrated. Our labs conduct legal testing that is ISO/IEC:17025 accredited and ISO:9001:2008 certified for use in the UK court system. 


Help and Guidance

Siblingship Testing Options

It is possible to establish three types of Sibling relationship;

  • Full Sibling vs Half Sibling - proving if two siblings share one or two parents in common. 
  • Half Sibling vs Unrelated - proving if two individuals share one parent in common or are unrelated.
  • Full Sibling vs Unrelated - designed for situations where siblings may either be related or not. 

Due to the complexities of sibling DNA testing your dedicated case manager, who is provided when you place your order, will discuss the exact family relationship with you.

Conclusive Range: With each sibling test our aim is  to establish either a 99% proof of relationship or 100% exclusion. This range depends on who can be tested within the family.
