What is Avuncular DNA Testing?

An Avuncular Test is an option that helps to determine the probability of a biological relationship between an alleged Aunt/Uncle with a alleged niece or nephew.

Testing Accuracy

An Avuncular Test could be a good testing option when attempting to determine paternity when a father, grandparents or siblings are unavailable to be tested. Unlike siblings who share approximately 50% of their DNA. Paternal aunts and uncles share roughly 25% of the same DNA.

When performing this test, for increase accuracy the known parent (mother) will need to be included.

DNA Markers

Our partner laboratory tests samples between and 18 to 24 genetic markers.

Sample Collection Method:

Cheek swabs collections

Buccal (cheek) swabs follow the standard, non-invasive method used to acquire a DNA sample when performing a avuncular test. The participant gently rubs a specialized cotton swab on the inside of their cheek to collect buccal cells. This collection approach is simple, quick, painless and yields an accuracy comparable to blood samples for comparative analysis.
