Description
Court-Admissible Aunt / Uncle Relationship Testing
Labs By Request offers legal (court-admissible) avuncular DNA testing to evaluate the biological relationship between an aunt or uncle and a niece or nephew. This test is commonly used when a presumed parent is unavailable for testing.
Common Legal Uses
- Immigration and visa documentation
- Probate and inheritance matters
- Social Security or benefits eligibility
- Court or government-required relationship verification
What This Test Evaluates
- Likelihood that the tested individuals share a biological family relationship through a common parent (the aunt/uncle’s sibling)
Avuncular testing provides probabilistic results, not absolute proof. Including additional family members can improve accuracy.
Legal Testing Requirements
- Strict chain of custody
- Photo ID verification
- Witnessed sample collection
- AABB-accredited laboratory analysis
- Court-admissible written report
Testing Options
- Legal Avuncular DNA Test
- Multiple aunts/uncles or siblings may be included to improve confidence
