Aunt DNA Testing

Aunt testing, also known as Avuncular DNA testing, will establish a biological relationship between an aunt and niece or nephew. The test is available as an appointment at one of our DNA Clinics. Or you can order an aunt DNA test kit by calling 0800 988 7107. Also, the aunt DNA test is available as a ‘peace of mind’ or legal DNA test. As a result, the latter option could provide you with court admissible DNA test results.

How does an Aunt 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 alleles (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 aunt test is that biologically related individuals should have more DNA in common than unrelated individuals. Therefore, on average the numbers from aunts will match at more DNA locations for their nephews and nieces.

Frequently Asked Questions

How long does it take for the aunt DNA test results?

The average analysis time in the lab 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 do I order an Aunt DNA Test?

Here are the options available to you:

  • 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 aunt 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 Aunt DNA Test?

The result of an aunt 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 an aunt and nephew/niece relationship.

Also, you can improve the chance of a conclusive DNA test result for your aunt test. Please call and speak to a Clinical Advisor who will explain the options to you.

Please refer to the disclaimer on this page for further information.


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:

  1. 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.
  2. 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.
