Aunt or Uncle DNA Test

Aunt or Uncle (also known as Avuncular) testing can be useful for establishing a relationship in situations where the parents are not available to be tested. It can be used to examine the relationship between a child and a possible aunt or uncle, although the inclusion of other close relatives is always recommended.

Aunt or Uncle DNA Relationship Test


Next Day DNA Test Results

As with all of our DNA relationship testing services we offer a 'Next Day DNA' service, as standard at no extra cost. This means that if all the DNA samples for your test arrive at our UK testing laboratory before 10am, we aim to send the test result to you by the end of the next working day by email.

Further Avuncular DNA Testing Information

This type of testing can be useful for establishing a relationship with a parent (such as a father) in situations where that parent is not available to be tested (the paternal aunt or uncle is therefore tested in place of the father).

It is possible to just compare the DNA profile of a child with an alleged aunt or uncle, however because of the patterns of DNA inheritance, it may not always reveal the true nature of the relationship or provide strong evidence. To increase the likelihood of the DNA analysis being able to establish the relationship with a missing parent (such as the father) it is always advisable to include the mother of the child, if this is possible.
