The avuncular test is regularly chosen to determine if an individual is biologically related to a sibling of the alleged father. When there are no samples available of the deceased alleged father or he is unavailable to participate in the test this is the most suitable testing option. A DNA sample of a brother or sister of the alleged father can be used determine this family relationship.
To increase the accuracy of the result we urge the mother to take part in the test so we can clarify one half’s of the child’s genetic profile. If the mother is unavailable we will provide extended testing at no additional cost.
