Avuncular DNA Testing in Gallatin, Tennessee
Avuncular DNA Testing With an Aunt or Uncle
When the possible father and his parents are out of reach, his brother or sister may still be able to help answer the question.
Overview
How avuncular DNA testing works
Avuncular DNA testing compares a child with the full sibling of a possible father. Since siblings share a large portion of their DNA, an aunt or uncle can provide a meaningful comparison.
DNA Paternity Solutions offers avuncular testing in Gallatin, Tennessee as an alternative path when grandparent testing is not possible. Including the child’s mother strengthens the analysis considerably.
A thoughtful option when other doors are closed
Asking a relative to participate can be delicate, especially after a loss. Many aunts and uncles welcome the chance to help, and the test itself takes only moments.
