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
