DNA Worldwide offer their unique Aunt/Uncle DNA test for situation where two individuals need to prove a biological relationship.

The test can be administered between an alleged aunt or uncle, and an alleged niece and nephew. What happens, say, if your father dies, and somewhere out there, you know he had a brother, your Uncle.

Our Aunts or Uncles DNA Testing kit can determine, up to a 99% accuracy, whether that man is, in fact, your father's brother. That information can offer a wonderful sense of connection to the deceased, and can become a new relationship to cherish.

The Aunt / Uncle DNA Test, also known as Avuncular Testing, measures the probabilities that two alleged relatives submitting specimens for testing are related as Participant 1 being either aunt or uncle to Participant 2. This test can be used for legal or personal purposes.

• Conclusive Range: <20% exclusion or >80% inclusion.
• Turnaround Time: 4-6 Weeks.
• Participants: One alleged aunt or uncle, one niece or nephew.
• Other Details: The probabilities can be increased greatly if other known relatives, such as a parent of the niece or nephew, are available for testing. Results may vary between 1% and 99% accuracy. DNA test assumes that there is a 50% prior probability of the relationship.

Procedure: Samples are collected from one alleged Aunt or Uncle and one Niece or Nephew at home or at a collection center (a parent is optional, but strongly suggested). The samples are obtained using a cheek swab. After samples are sent to the laboratory, results will be available within 3-6 weeks. The conclusive range for these results are <20% exclusion="" or="">80% inclusion.We do not guarantee that results will fall into this conclusive range, and results may vary between 1% and 99% accuracy.
