Grand Parentage DNA Testing
Establish paternity via an alleged grandparent
Looking to confirm relatedness with a grandchild? If the alleged father is not available for paternity testing, either one or both parents can be tested instead. Whether you need answers for personal assurance or legal matters, we can help you attain the certainty that you need.
A grandparentage DNA test can be as accurate as a paternity test, though the conclusiveness of the results may vary more. For instance, while a father-child paternity test often yields a probability of 99.9% or higher, a test involving only one paternal grandparent might show a relationship probability of around 92%, which is still considered conclusive. To enhance the accuracy of the results, it is recommended to test both paternal grandparents if possible, along with the child’s mother. When both paternal grandparents and the mother are involved, the probability of paternity is typically 99.9% or higher.
