Accurate Family Relationship Answers

An Aunt/Uncle, or Avuncular, DNA test is a good option to use to determine paternity when the father is not available for testing. An avuncular test will determine if a sibling (a full blood brother or sister) of the father in question is related to a child, and thus prove paternity.

The report generated by an avuncular DNA test will indicate the probability of relation. As siblings share roughly 50% of their DNA, a niece or nephew would share approximately 25% of their DNA with their aunt or uncle. Our accredited laboratory will test for 24 genetic markers to ensure your results the highest accuracy.

  • We always include the mother in the testing process, especially when testing for legal reasons. Using her genetic DNA markers we can provide the most precise and accurate report. Not including the mother, or known parent, can lead to inconclusive results.
