Aunt Uncle DNA Test
From £199
Order Now!
The lab cannot perform this test if the aunt / uncle is NOT a full sibling to the alleged father in question.
The Who’zTheDaddy? AuntUncle test sometimes called an avuncular test, determines that a person is the biological aunt or uncle of their niece or nephew in cases where the father of the child is not available for testing. Our test is priced at £199 for testing 1 aunt, uncle and 1 niece or nephew (a total of 2 individuals). Who’zTheDaddy? will have your results ready and emailed in only 5-7 working days.
Science behind the test
Testing the genetic relatives of the alleged father can tell you whether the child is the biological child of the alleged, untested father and establish if the aunt, uncle is related to their niece or nephew.
The paternity of a child can be indirectly established by testing blood relatives of his or her father. The alleged father’s brothers or sisters will have genes in common with their brother (the alleged father of the child) and with their niece or nephew.
When processing an avuncular DNA test, the laboratory will establish the genetic profile of the alleged relative and the child. An avuncular index is calculated using these genetic profiles. If the avuncular DNA index is less than 1.00, it indicates that the tested persons are not related. If the avuncular DNA index is greater than 1.00, it indicates that the tested persons are more likely to be true biological relatives. The higher the avuncular DNA index value, the greater the likelihood that the tested applicants are true biological relatives.
Who’zTheDaddy?™ strongly recommend sending the sample of a known parent if possible as this can help us obtain a more conclusive result.
A Note About this Test
Avuncular tests will never reach the same levels of accuracy as a paternity test although results can give a very good indication as to whether there is a biological relationship between the people tested. This is because parents share around 50% of their genes with their children whilst aunts and uncles only share around 25% of their genes with niece, nephew. If there is any way of testing the father and thus collecting a DNA sample from him, Who’zTheDaddy? recommend carrying out a paternity test. A paternity test will provide much more accurate results than an avuncular test or missing parent testing, which should be considered as a second option if the possibility of carrying out a paternity test has been excluded.
Sample Collection
Who’zTheDaddy?™ offers the most straightforward, simple and accurate sample collection process using oral swabs. Out kits are packed with 4 orals swabs for every person tested. You can follow the instructions inside your kit in order to collect the required samples. Orals swabs are sterile, cotton bud like utensils that need to be rubbed in the mouth for just ten seconds and then allowed to dry. You will also have instructions and consent forms.
FAQs
What testing do you suggest if both grandparents are available?
If both the alleged father’s parents are available for testing we can recommend a grandparent test or missing parent test. Using the samples of both paternal grandmother and grandfather, we can reconstruct the profile of the grandchild’s alleged father. This test provides a more accurate result than an Avuncular test with samples from the father’s siblings. Click here to read more about Grandparent DNA Testing.
Should I Carry Out a Paternity Test?
If there is any way of testing the father and thus collecting a DNA sample from him, Who’zTheDaddy?™ recommend carrying out a paternity test. A paternity test will provide much more accurate results than an avuncular test or missing parentesting, which should be considered as a second option if the possibility of carrying out a paternity test has been excluded.
