How is this done?
Avuncular DNA tests can confirm paternity by using the DNA samples from the siblings of the alleged father. As siblings have a common DNA, you might also receive some from your biological father. If that DNA matches with the siblings of your alleged father, it will prove that you are a part of that family.
During this test, the lab determines the genetic material of both parties, and the avuncular index is determined. If the index is less than 1.00, it means that they are not your relatives. For example, if you had taken an uncle DNA test and your avuncular index is 1.50, you are related to each other but if it is 0.50, both parties are not related to each other.
Since all members of the family share at least 25% of common DNA, it is possible to find the biological father by avuncular testing. DNA tests for child and aunt can be done only if she is a full sibling to the alleged father. The same goes for the uncle.
How to increase accuracy?
You can increase the accuracy of the test by including samples of a known parent when possible. If the testing is done to find the alleged father, the mother should participate in the test too.
Difference between legal and non-legal testing:
You must always choose a laboratory that is authentic and certified to practice paternity tests. During a legal DNA test, all the processes will be documented and all participants will be photographed. You must show your government ID to prove your identity. Only if the test is legal, it can be used as legal evidence.
A non-legal test is more for personal use. It is just to find the uncle or aunt of a child to establish biological relations. Most laboratories perform both legal and non-legal tests.
