Grandparent DNA Test
To confirm a biological relationship when a possible father is unavailable
What is Grandparent DNA Testing?
Interested in verifying a biological relationship with a grandchild? In cases where the potential father is unavailable for paternity testing, one or more of his parents can step in. It's also beneficial for the child's mother to include her DNA, as it expedites analysis and enhances result reliability. Whether you seek answers for personal assurance or require a legal report, we deliver the precise information you're seeking. Your report will be accessible in your secure online account just 5 business days after receiving all grandparent test samples at the lab.

Grandparent DNA Test Near Me
The primary motivation for grandparents to undergo a DNA test is often to establish the truth regarding a biological relationship. However, there are additional potential reasons to consider a grandparent paternity test, such as:
Gaining insights into medical history.
Determining eligibility for Social Security benefits.
Supporting inheritance claims.
Validating insurance claims.
It's crucial to note that all results are kept strictly confidential, and your private genetic information is never disclosed or sold to external parties.

Testing Options for Grandparent DNA Testing
There are two primary ways to conduct a grandparent DNA test: legal and personal knowledge.
Legal Option: Legal test results can serve as legal proof of paternity and be submitted to immigration agencies or court proceedings. GameDay DNA arranges for DNA sample collection at a nearby location. A professional collector handles all identification and paperwork, sending the package to DDC for testing.
Personal Knowledge Option: If you only need maternity DNA test results for personal peace of mind and not for legal purposes, you can use an at-home grandparent DNA test to collect your sample and send it to DDC for testing. Please note that these results are not suitable for court use.
Tip: If you anticipate needing court-admissible results in the future, we recommend starting with a legal test to avoid the need for testing twice.

More About the Grandparent DNA Test
-
A grandparent DNA test is as accurate as a paternity test, although the conclusiveness of results varies more. For example, the probability of a relationship between a father and child is almost always 99.9% or higher, but for a single-grandparent test (where only one paternal grandparent is tested instead of both paternal grandparents), the probability of a relationship might be 92%—which is nevertheless still considered a conclusive result. To strengthen the conclusiveness of test results, we recommend that both paternal grandparents test—if possible—and that the child’s mother participates in testing as well. When both paternal grandparents and the mother participate in testing, the probability of paternity is nearly always 99.9% or higher.
-
You can do this DNA test using samples from just one paternal grandparent and the child; however, the chances of obtaining conclusive results are reduced. If possible, we always recommend including the mother’s DNA in both single-grandparent and grandparentage (both paternal grandparents) DNA tests. Ideally, both paternal grandparents would test, along with the child and the mother.
-
Yes, a grandparent test can be done without the mother, although we highly recommend that the mother be included as well. Her participation helps the analysts to more clearly determine which of the child’s DNA comes from the father’s side and which comes from the mother and it can also help to strengthen the probability of relationship percentage.
-
Yes; a grandparent DNA test can be used for legal reasons as long as a chain-of-custody procedure has been set up and followed:
The test is ordered directly from DDC
DDC schedules a DNA-collection appointment for test participants at a convenient facility near them
Test participants provide proof of identity at the appointment and DNA collection is witnessed
The facility signs paperwork and returns samples to the lab for testing
Results from a legal grandparent test are court-admissible and can be used for legal reasons such as Social Security, inheritance rights, custody, and more. Results of an at-home grandparent DNA test cannot be used legally.
-
Whether the test is an at-home or a legal one, the responsibility is on the tested parties to ensure all parties and/or legal guardians agree to testing.

Understanding results for a grandparent DNA test is a little tricky, since there can never be a straight “yes or no” answer in relationship testing. Calculations for relationships such as grandparent, avuncular (aunt/uncle), and siblings all involve statistics, and a probability of relationship is given as a percentage in the report:
90% or higher: the relationship is supported by DNA testing
9% – 89%: inconclusive result, and additional parties need to be tested
Below 9%: the relationship is not supported by DNA testing
If a probability of relationship (PRI) of 92% is given for a grandparent test, the result could be understood as: “There is a 92% probability that the people tested share a grandparent/grandchild relationship.”
