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 average analysis time in the laboratory for the grandparent DNA test is around three to four working days. But this does not include the quality checks needed for sample integrity or your consent paperwork. So, from receipt of your samples at Crystal Health Group, it takes on average of about three to five working days. If there are any unforeseen delays, for example, such as the paperwork we receive not being quite right, we will contact you as soon as possible to let you know.

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.
