Grandparent DNA Testing
The grandparent DNA test will establish the biological grandparents of a grandchild. The test is available as an appointment at one of our DNA Clinics. Or you can order a grandparent test kit for free from our online store. Also, the grandparent DNA test is available as a ‘peace of mind’ or Legal grandparent test. As a result, the latter option could provide you with court admissible DNA test results.
How does a Grandparent DNA Test work?
As with a paternity test, a DNA profile is produced for each person. The test analyses different genetic locations on the DNA strand. First, the allele (alternating form of DNA) at each location is identified by a number. Next, the DNA profiles of the test participants are then compared.
The logic behind the grandparent test is that biologically related individuals should have more DNA in common than unrelated individuals. Therefore, on average the numbers from grandparents will match at more DNA locations for their grandchildren.
Frequently Asked Questions
How long does it take for the Grandparent DNA test results?
The typical analysis time for a grandparent test at Crystal Health Group is by the *next working day. This estimate applies to the lab analysis itself and does not account for additional time required to verify sample integrity or process the necessary consent paperwork.
In the event of any delays, such as issues with the submitted paperwork, we will contact you promptly to keep you updated.
* Returned samples are checked to ensure everything is complete and ready for analysis. If we spot anything that could delay your results, we’ll get in touch quickly to help resolve it.
How do I order a Grandparent DNA Test?
Here are the options available to you:
- Order a free grandparent test from DNA Clinics*
- Call 0800 988 7107 to make an appointment at a DNA Clinic or order a *DNA self-collection Home Kit
- Call 0800 988 7107 to arrange a home visit from a sample collection officer
- You or your solicitor can contact us to organise a Legal Grandparent DNA Test for court purposes
* Please note, you can only use self-collection kits for peace of mind purposes only. This test cannot be used for legal purposes.
How accurate is the Grandparent DNA Test?
The result of a grandparent DNA analysis is based on statistical calculations. As such, this produces a probability indicating whether two individuals are true biological relatives. The statistical analysis is based on factors such as:
- The number of matches within the DNA profiles.
- How likely it is that the same allele would be found at that same DNA location, if testing a random, unrelated individual from the same ethnic background.
These calculations determine the most likely relationship between the individuals tested. This could be a grandparent / grandchild relationship, or unrelated.
Also, you can improve the chance of a conclusive DNA test result for your grandparent test. Please call and speak to a Clinical Advisor who will explain the additional options available to you.

Did you know?
While other companies analyse just 23 locations on the DNA molecule, we standardly test 43 different loci for all grandparent DNA relationship tests to ensure the most reliable and accurate results. In addition, Including a known parent can also increase the accuracy of your results. Again, while other DNA testing companies will charge you for this, we offer this option at no additional cost.
Important Information About DNA Test Results
DNA testing is designed to provide clear and reliable results and is analysed by a UKAS ISO 17025-accredited UK laboratory. In the vast majority of cases, testing provides a conclusive outcome.
However, as with all genetic testing, there are rare situations where the DNA evidence does not provide enough statistical certainty to confirm or exclude the biological relationship being tested. This is more likely in more complex relationship tests or where a limited number of participants are included.
If a result is inconclusive, we will always explain what this means clearly and discuss any available options that may help achieve a more informative outcome, such as including additional participants or further laboratory analysis.
Because the laboratory analysis and reporting process has already been completed, refunds are not issued for inconclusive results.
Local DNA Clinics, and mobile locations throughout the UK
For your convenience, we have a network of DNA Clinics throughout the UK. As a result, we can provide grandparent test appointments for you in your local area. Alternatively, we can arrange for a certified sample collection officer to visit your home or other convenient location of your choice.
