Avuncular DNA Testing (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 testing service typically includes the child and one aunt or uncle, but you may add more persons as needed; for instance a second child or additional parent.
When the issue of an avuncular relationship is in question, that is, the relationship between aunts or uncles with their nieces or nephews, the recommended method is to test the available parent of the niece of nephew in question. In the vast majority of cases, aunt/uncle testing is used in the place of a paternity DNA test when the alleged father is unavailable or deceased.
In situations where the child's known parent such as the Mother is unavailable for testing, a avuncular DNA test can still be performed.
As mentioned, unlike a DNA paternity test which will always provide a conclusive result, avuncular DNA tests are different. When an avuncular DNA test is conducted, the laboratory will determine the genetic profile of the alleged relatives based on the type of genetic material exhibited by each person, an avuncular index is determined. If the avuncular index is less than 1.00, this indicates non-relatedness. If the avuncular index is greater than 1.00, this indicates that the two tested individuals are more likely to be true biological relatives. The higher the value of the avuncular index, the greater the likelihood that the two individuals are biological relatives.
