Aunt & uncle test

Avuncular tests calculate the likelihood of relatedness between a child and an aunt or uncle.

A child inherits exactly half of their genes from their biological father and the biological father shares around half of his genes in common with his full sibling, therefore the child will share around half of its paternal genes in common with the full sibling of the biological father. Based upon the number of genetic matches, the laboratory calculates the statistical likelihood that the alleged aunt/uncle is biologically related to the child versus being unrelated.

It may not be possible to achieve a conclusive result. Even though the siblings may have the same biological parents, the alleged father is not genetically identical to the alleged sibling and have different genetic markers. On the average, testing an alleged father’s full sibling allows us to determine only half of his genes.

To increase the certainty of the results, testing the mother of the child is strongly recommended, as this allows for identify genetic markers of the child that were inherited maternally and to eliminate them from consideration as possible paternal markers.

The test protocol is very rigorous and precise, and includes the reading of 22 DNA sequences (22 loci) with 99.99% accuracy.

Simplified Process:

1. Order your test and receive a kit containing two sample envelopes (for one child and one alleged aunt or uncle). 
2. Receive your kit: activate your test using the activation code provided. Collect the samples by following the instructions included in your kit.
3. Return the samples using the prepaid return label included in your kit so they can be analyzed in the laboratory.
4. Access your results: view your confidential report through our secure online portal.

Results are ready within five business days after the samples are received at the laboratory.
