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 between 5 to 7 working days. 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. Once we receive your samples, the overall processing time is usually around 7 working days.
In the event of any delays, such as issues with the submitted paperwork, we will contact you promptly to keep you updated.
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.
Disclaimer
Due to the science of complex DNA relationship testing and the chance nature associated with DNA inheritance, there is a small risk of an inconclusive result with this test. An inconclusive result means that the DNA analysed and compared between individuals does not provide enough evidence to establish the biological relationship being tested. The risk of obtaining an inconclusive result varies due to several factors including, the test participants available for testing, the individual’s specific DNA profiles and how unique or common they are and the number of locations on the gene tested.
It is important that you are aware of the risk of an inconclusive result before ordering or booking this test, as you will be signing consent to confirm your understanding and acceptance of this. Refunds will not be issued for inconclusive results.
However, we will always attempt to achieve a conclusive result for your DNA test. As such, there may be further options available to you to achieve this (additional fees apply). These are:
- The addition of other test participants. Crystal Health Group will recommend which individuals could be included to improve the chance of obtaining a conclusive result.
- Further analysis to compare additional loci (DNA locations).
If you are using the DNA Clinics service and booking an appointment, the above options will be explained to you. If you are ordering a self-collection kit, please call 0800 988 7107 and speak to a member of our team about these options before you order a DNA kit.
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.
