Establishing biological relationships is critical for peace of mind and legal clarity. When an alleged father is unavailable for testing, a grandparent DNA test provides a reliable alternative. At Brashan DNA Services, we use advanced laboratory techniques to resolve uncertainty for families across the UK.
How does a grandparent DNA test work?
A grandparentage test compares the genetic profile of a child with one or both paternal grandparents. We examine specific STR (Short Tandem Repeat) markers to determine the statistical likelihood of a biological link. Because a child inherits 50% of their DNA from each parent, grandparents share approximately 25% of their DNA with their grandchildren.
Our laboratory calculates a grandparentage index. A result above 1.0 indicates a high probability of relationship, while a result below 1.0 suggests the individuals are not related. For the most accurate results, test both grandparents if possible, as this allows for a more complete reconstruction of the missing parent’s genetic profile.
Why do families choose this test?
Families typically request a grandparent DNA test when the alleged father is deceased, missing, or unwilling to participate in a standard paternity test. This service is essential for:
- Peace of Mind: Confirming biological heritage for personal knowledge.
- Inheritance Claims: Providing evidence for probate or estate disputes.
- Social Security Benefits: Establishing lineage for official claims.
- Immigration: Supporting family visa applications through an Immigration DNA Test.
