What is an Avuncular DNA Test?

A DNA Avuncular test is genetic test that determines if an alleged aunt/uncle is biologically related to a niece/nephew. This testing option is utilized when the alleged father, siblings, or grandparents of the alleged father are unavailable to be tested.

Common Uses

To confirm paternity when the biological father is unavailable: If the biological father of a child is deceased, unwilling to participate in DNA paternity testing process, or cannot be located, an avuncular DNA test can be used to determine whether the child is related to the father’s siblings. This can provide valuable information for the child’s family and may be necessary for legal purposes.

To gain peace of mind: Some people may choose to undergo an avuncular DNA test to simply confirm their biological relationship to a child, even if there is no doubt about paternity. This can be helpful for providing peace of mind and resolving any lingering questions about the relationship.

For legal reasons: In some cases, an avuncular DNA test may be required for legal purposes, such as inheritance claims or child support hearings. This is especially true if the biological father is deceased or unable to participate in a paternity test.
