The DNA Worldwide Aunt/Uncle DNA test is the most detailed in the world, covering 46 DNA Markers and is for situations 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. The test is commonly used where an alleged father is not available for testing but his brother or sister are.

The Aunt or Uncle DNA Testing kit can determine with 100% accuracy, up to a 99.99% positive proof of relationship or 100% exclusion. 

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: 5-10 Days
• 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 100% exclusion to 99.99% positive proof of 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 5-10 Days.

The conclusive range for these results are <20% exclusion or >80% inclusion. We do not guarantee that results will fall into this conclusive range, however with our detailed DNA testing of up to 46 DNA Markers, DNA Worldwide provide conclusive results for Aunt/Uncle tests in up to 98% of cases.
