The DNA Family Check Grandparent Test investigates the likelihood of biological relationships between potential grandparents and a grandchild when the parents are not available for testing. This at-home DNA test kit is a useful tool for grandparents to check the probability that their son or daughter is the true biological parent of a grandchild.

Our non-invasive cheek swab makes it easy for individuals of any age to collect DNA samples comfortably at home. Return your samples using the prepaid shipping label. Your results will be accessible through a secure online portal within 1-2 business days.

The DNA Family Check Grandparent Test is best suited for situations when the alleged father or mother is deceased or otherwise unable to participate in DNA testing. If the parent in question is available for testing, the paternity test or maternity test is highly recommended as it can provide 99.999%+ definitive answers about biological relationships, compared to the statistical likelihood from a grandparent test.

How it works




The DNA Family Check Home Grandparent DNA Test is specifically designed to establish the biological relationship between grandparents and their grandchildren when the alleged father is not available for testing. It’s a powerful tool for grandparents seeking to confirm whether their son is the true biological father of their grandchild, especially in situations where the alleged father is deceased or cannot participate in a paternity test. With painless mouth swab sample collection and quick results in 1-2 business days, you can have peace of mind in the privacy of your home. Our accredited laboratory ensures double testing for absolute accuracy. Order your test today and discover your biological connection.

The DNA Family Check Grandparent Test is a reliable method of determining investigating the relationship between a potential grandparent and grandchild. Either the grandmother, grandfather or both grandparents can take this test. However, unlike paternity or maternity tests, grandparentage tests provide a statistical likelihood rather than a definitive answer. The results are provided as a “combined kinship index” indicating the likelihood of the tested individuals being related as grandparent and grandchild.

Once the samples arrive at our state-of-the-art laboratory, your results will be ready in just 1-2 business days. You can easily keep track of your test status within your secure online portal, and we’ll notify you the moment your results are available.

Yes, it’s possible to conduct the test with only one grandparent. However, for the most comprehensive and accurate results, we recommend including both grandparents in the test, if possible. When both grandparents are tested, we can analyze a larger number of genetic markers, thereby enhancing the accuracy of the test and providing a more robust statistical likelihood of the biological relationship.

While the Home Grandparent DNA Test provides valuable information, particularly in cases where the alleged parent is unavailable, it’s important to understand that it’s not as definitive as a paternity or maternity test. The Grandparent DNA Test offers a probability or likelihood of a biological relationship, rather than a conclusive result. It is a valuable tool when direct parentage tests are not feasible, helping to piece together family relationships.

Yes. We respect your privacy and handle all information and samples with utmost confidentiality. All test kits ship out discreetly in an unmarked package. Your results are only accessible to you via secure online access, and we do not share or sell your data to any third party.

Yes, individuals residing at different addresses or even different countries can be tested. We can split the kit, sending each component to the specified locations. Each person can then collect their own samples and send them back to our laboratory for analysis. Our lab will match the samples using the unique identification numbers provided in each kit. To arrange a split kit, include the full names, mailing addresses, and relationship type (e.g., grandmother, grandfather or grandchild) of each person in the comments box of the online order form. Alternatively, you can contact our customer support team who will assist you in setting up the split kit.

While our home Grandparent Test provides the same accurate results compared to our legal tests, it is not admissible for legal purposes as it is not a chain-of-custody test. Legal testing requires sampling to be done and witnessed by a third-party impartial collector, and all participants must provide identification at the time of the appointment.

“My ex-girlfriend contacted me to say that I may be the father of her 5 year old daughter. Your test proved that I am the true biological father. It’s a life changer. Thank you.”

Jared, SD

“I was very impressed with the ease and discretion of the testing process. I received my results quickly and quietly.”


“My husband has always mentioned that our two children maybe did not belong to him and accused me of being involved with his friend at the time that our children were conceived. I knew that this was not true. We finally decided to get a paternity test done to put an end to this. Sure enough, the results of the paternity test indicated greater than 99.9999% that he was the father of our children. Our family is now closer than ever before.”

R. Stern, Seattle, WA
