Avuncular DNA Test

To establish a child’s relationship with a possible Aunt or Uncle.

Looking to prove a biological relationship through DNA testing for a possible Aunt or Uncle?

When a possible parent isn’t available for testing, one or more of the parent’s siblings can participate. A person with parental responsibility for the child must consent to the test if the child is under 16. If the mother is available she is encouraged to add her DNA to the test to help expedite analysis and to produce a more conclusive result. Results are posted to your secure online account 5-7 business days after all samples are received at the lab. The report can be used for personal knowledge only, or it can be used in court if you choose to do legal testing. Contact our experts today for a free consultation.

Testing Options for Avuncular DNA Testing

Legal: Legal results for this type of testing can be submitted to court as legal proof of a biological relationship. DDC helps you locate a DNA-sample collection provider near you. The professional collector then compiles all identification, completes paperwork for the test, and sends the package to DDC for testing.

Personal Knowledge: If you need avuncular DNA testing results solely for peace of mind and not for legal reasons, you have the option to collect your DNA at home and send it to DDC for testing. Keep in mind results are not court-admissible.

TIP: If you think you may need results for court in the future, we suggest you do a legal test in the first place so you only have to test once.

More About Avuncular DNA Testing

Q: What relatives should participate in an avuncular DNA test?

A: Generally, participants in an avuncular DNA test are the child and either a brother or sister of the possible father in the case. Whenever possible, the mother of the child should also contribute her DNA to testing since her participation can definitely help to strengthen results.  

Q: What if the paternal aunt is not a full sibling of the possible father?

A: We cannot test half-siblings of a possible father. It must be a full-sibling relationship in order to obtain the most conclusive results possible. 

Q: For an avuncular DNA test, can first or second cousins be tested instead of an aunt or uncle?

A: No; the participation of cousins isn’t helpful for avuncular DNA testing or any other type of relationship test, since the percentage of DNA they might share with the child in question is low. The participants in the test should be the child, the possible father’s sister or brother, and the mother of the child.
