 A legal Sibling 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.

Sibling Testing Options

We can establish three different types of Sibling relationships including;

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

It is our aim with our sibling tests to establish either a 99% proof of relationship or 100% exclusion. This range depends on who can be tested within the family.
