Avuncular DNA Test
The Avuncular DNA test at ARCpoint Labs of Nashville South determines paternity or maternity through testing a sibling of the alleged parent, that is, an aunt or uncle. Aunt or Uncle DNA testing determines the probability that an individual is the biological aunt or uncle of a child. This type of DNA testing is referred to as Avuncular DNA analysis.
The term avuncular is actually derived from avunculus, a greek word that refers to the maternal uncle. In DNA testing it is used to designate a DNA test that involves either paternal uncle or a paternal aunt. An avuncular test is another way, though less precise and certain, to determine paternity. It can be used when the alleged father is deceased or not available for another reason.
We recommended testing the available parent(s) of the child in question. If a child’s parent is unavailable, an avuncular DNA test can still be performed with an alternate DNA sample (hair, toothbrush, etc.) for a court-admissible DNA test.
Alternative Methods for Proving Paternity
Unlike a DNA paternity test, which provides a relationship result, avuncular DNA tests are different. An avuncular DNA test determines the genetic profile of the alleged relatives, which creates what is known as the avuncular index.
When the avuncular index is less than 1.00, it is established that no relationship exists. When the avuncular index is greater than 1.00, it is more likely that the tested individuals are true biological relatives. ARCpoint Labs of Nashville South uses state-of-the-art DNA testing methods, yielding the most accurate results.
A Chain of Custody is used to establish the identity of all persons tested. An avuncular test determines the statistical probability that a biological relationship exists between test participants.
