Who needs to be tested?

One (1) Mother, one (1) Child and one (1) Full Sibling of the deceased or missing Alleged Father

An avuncular test is performed to determine if two individuals are related to each other as aunt–nephew (or niece) or as uncle–nephew (or niece).

Turnaround Time

  • Five (5) business days from receipt of all samples

Chain-of-Custody Requirements

Chain-of-custody requirements must be fulfilled for test results to be defensible in any legal situation, such as inheritance disputes. These requirements include the following:

  • Samples are collected by a neutral third party, such as a clinic or laboratory
  • The individuals tested are positively identified (i.e., they present a government-issued ID to be photocopied and/or they are photographed and fingerprinted)
  • A standard DNA kit is used
  • Each party completes and signs a Client Identification and Consent Form
  • Guardianship of tested minor must be verified at the time of signing consent
  • The kit may not be in the possession of the clients prior to or after being collected

Non-Chain-of-Custody Requirements

This test is only available as a non-chain-of-custody test. Results of this test are for personal knowledge only and may not be used for legal purposes.

  • An in-home kit is used, and buccal samples can be collected by the patients themselves or assisted by collection site, such as High 5 Fingerprinting, at a time and place of their choosing
  • Since the origin of the samples cannot be verified, names are listed on the report in the same way they are labeled on the samples
  • A unique barcode is assigned to each kit and appear on the report as a reference for the case
  • Barcoded kits are assigned to your account for easy reference 


  • The avuncular testing option should be discussed if the alleged father is deceased or unavailable, and post-mortem, grandparentage, or reconstruction testing cannot be performed
  • Generally speaking, biological relationship testing such as genetic reconstruction and siblingship testing is not as definitive as DNA parentage testing. It is not possible to determine with absolute certainty whether two people are siblings or biologically related in some way other than the parent-child relationship. We can only test for whether they are more or less likely to be related
  • Avuncular testing will provide a likelihood that the individuals tested are more likely, or less likely, to be related as Aunt/Niece, Uncle/Nephew, etc, and a Combined Related Index is provided for the relationship being tested
