Overview
The primary purpose of the avuncular DNA test is to establish or exclude a biological relationship between a child and an alleged aunt or uncle. This is often necessary when the alleged father is deceased, absent, or unwilling to participate in a paternity test. The test can also be used to confirm kinship for legal matters such as inheritance, child custody, or immigration. By analyzing genetic markers inherited from common ancestors, the test provides a statistical likelihood of the relationship, helping families and legal authorities make informed decisions.

Understanding Your Results
Probability ≥ 99.9%
The alleged aunt/uncle is biologically related to the child.
Probability < 0.1%
The alleged aunt/uncle is not biologically related to the child.
Probability between 0.1% and 99.9%
Inconclusive; additional testing or family members may be required.
If you have questions about the results or need assistance with legal proceedings, consult a genetic counselor or legal expert. For medical concerns, speak with your primary care physician.
