Establishing biological relationships is vital for family clarity, legal rights, and peace of mind. When an alleged father is unavailable for a standard paternity test, a grandparent dna test offers a reliable alternative to confirm lineage. At Brashan DNA Services, we provide expert dna testing services to help UK families find the answers they need.
How does the testing process work?
Grandparentage testing relies on the fact that a child inherits 50% of their DNA from each parent, which means they share approximately 25% of their genetic makeup with each biological grandparent. By comparing the genetic profiles of the child and the grandparent, our experts can determine the statistical likelihood of a biological bond.
Follow these steps to get started:
- Order your kit: Visit our shop and select the grandparentage test.
- Collect the samples: Use the provided buccal (cheek) swabs to collect DNA from the grandparent and the child. It is a painless, non-invasive process that takes seconds.
- Return the samples: Send the samples back to our accredited UK lab in the pre-paid envelope provided.
- Receive your results: Our experienced technicians will process the samples and provide highly accurate results within days.

Why involve the mother?
While we can perform a grandparent DNA test with just one grandparent and the child, we strongly advise including the biological mother's sample whenever possible. Including the mother allows our technicians to "mask" the maternal DNA, making it significantly easier to isolate the paternal genetic markers. This process ensures the most conclusive and highly accurate results available.
Accuracy you can trust
At Brashan DNA Services, we prioritise precision. Every sample is handled by experienced technicians in a state-of-the-art accredited UK lab. We utilise advanced Short Tandem Repeat (STR) analysis to examine multiple genetic markers. If the results are for legal purposes, such as inheritance or immigration, we ensure a strict chain of custody to meet court-admissible standards.
