Grandparentage Testing
A grandparentage test determines the biological relationship between a child and the alleged grandparents. A paternal grandparentage test, in which the alleged father’s parents are tested with the child, is often used to determine family relationships when the alleged father is not available. Maternal grandparentage tests also may be used to determine family relationships in situations where an alleged mother is not available.
Grandparentage tests usually are performed using a Chain of Custody, a documentation process that makes the test results legally admissible (accepted by courts and other government agencies). Results of a grandparentage test are often used for Social Security and inheritance claims.
If you would like to take the grandparentage test for personal knowledge only and do not intend to use it for any legal purpose, please call one of our case managers at 1-888-362-2592 to discuss the in-home option.
Tested Parties
In a standard paternal grandparentage test, a child, the mother, and both alleged paternal grandparents are tested. We also may perform a motherless test, which takes a longer time for analysis and is more costly.
For a standard maternal grandparentage test, a child, the father, and both alleged maternal grandparents are tested. A fatherless test, which takes longer and is more costly, is an option we also provide.
Convenient Appointment Locations
We have the largest sample collection network in the United States. If you live in the U.S., we can schedule your appointment at a location close to your home or work, often on the same day. There are thousands of collection sites affiliated with us all over the U.S. and worldwide.
The collection facility charges a sample collection fee of $90 for the grandparents, the child, and the parent (i.e., the mother in a paternal grandparentage test). For your convenience, we pre-pay the collection fee and add it to your balance.
Notarized Results
Standard grandparentage tests are completed within 5 working days after receiving samples from all tested parties. Motherless or fatherless cases are completed within 9 working days, due to the extended analysis required. All test results are signed by one of our M.D. or Ph.D. scientists and notarized.
