Our Grandparents DNA test has an accuracy of 99.9%, whereas a single grandparent test has an accuracy of 92%. It is also used to establish a paternity test in case of the unavailability of the alleged father. In such cases, a Duo Grandparents DNA test, along with maternity test, strengthens the conclusiveness of these results resulting in an accuracy of 99.9% or more. Other than strengthening a paternity test, the Grandparent DNA test is also used for medical history, insurance claims, and inheritance claims.
