Accredited USA Lab
Testing performed by a fully accredited laboratory in the United States.
Home Grandparent DNA Test
Our Grandparent DNA Test helps determine whether a biological relationship exists between a grandparent and grandchild by comparing their DNA profiles. Testing can be performed with one grandparent; however, including the child’s mother and/or the second grandparent, along with selecting 46-marker analysis, can significantly improve statistical confidence. Because grandparent testing is more complex than direct paternity testing, analyzing more genetic markers can strengthen statistical confidence. Click Here For A Legal Grandparent Test.
Accredited U.S. Laboratory – 34 and 46 Marker Analysis Options.
Our 34-marker Grandparent DNA Test analyzes 24–34 genetic markers and can be an excellent option when the child’s mother participates in testing. Maternal participation helps refine the analysis and can improve the statistical confidence of the results while helping families manage testing costs.
Some DNA tests analyze fewer genetic markers. Our expanded 24–34 marker analysis provides greater genetic comparison when evaluating grandparent and grandchild relationships and may help reduce inconclusive outcomes.
Testing can still be performed even when the mother is unavailable, although including her DNA often improves the strength of the analysis.
All testing is performed in an accredited U.S. laboratory, ensuring professional laboratory standards, secure sample handling, and strict confidentiality. PaternityUSA does not sell, share, or store DNA data in external databases, and results are typically available within 2–3 business days after the laboratory receives the samples.
Our 46-marker Grandparent DNA Test provides advanced genetic analysis designed for complex family relationship testing. In this test, all 46 genetic markers are analyzed in every case, allowing for deeper DNA comparison when evaluating grandparent and grandchild relationships.
Because grandparent testing is more complex than direct paternity testing, analyzing a larger number of genetic markers can strengthen statistical confidence. By examining nearly twice as many markers as many standard 20–22 marker tests, this enhanced analysis provides additional genetic evidence and may help reduce inconclusive outcomes, particularly when a parent is unavailable for testing.
All testing is performed using validated laboratory methods in accredited U.S. facilities, ensuring professional laboratory standards, quality control, and secure sample handling. At PaternityUSA your personal and genetic information is treated with strict confidentiality and is never sold, shared, or stored in external databases.
Results are typically available within 2–3 business days after the laboratory receives the samples, providing timely answers while maintaining rigorous analytical standards.

How Does Our Home Grandparent DNA Test Compare?
The Grandparent DNA Test provides a reliable way to evaluate a biological relationship between a child and one or both grandparents when a parent is unavailable for testing. All samples are analyzed by an accredited U.S. laboratory using validated procedures to deliver accurate, confidential results families can trust.
Two testing options are available based on your situation. The 24–34 marker test is our standard option and includes the mother at no additional cost when she is available, allowing for stronger and more conclusive results. For cases where the mother cannot participate, the 46-marker premium test analyzes nearly twice the genetic data used by many laboratories, providing significantly greater statistical confidence.
Including the mother when possible—or selecting the 46-marker option when she is not available—helps ensure the most conclusive outcome. Once all samples are received by the laboratory, results are typically available within 2–3 business days.
For more than 25 years, families across the United States have trusted PaternityUSA for accurate, private DNA testing performed with professional laboratory standards and transparent pricing.

Answers to Common Home Grandparent DNA Test Questions
Find clear answers to common questions about the testing process, shipping options, turnaround times, and how to achieve the most accurate and reliable results.
If test participants are located in different cities or states within the contiguous United States, additional shipping addresses can be added during the ordering process. Each participant will receive their own DNA collection kit shipped using the same method selected for the primary address, and each kit will include a prepaid return mailer. All kits are linked to the same order using unique barcodes to ensure proper processing. For shipments to Alaska, Hawaii, U.S. territories, or international locations, please contact our office to confirm availability and pricing.
Many laboratories analyze only 16–22 genetic markers for relational testing. PaternityUSA offers an advanced 46-marker testing option, which analyzes more than twice the genetic data to provide greater statistical confidence. The 46-marker test is especially recommended when only a grandparent and child are available for testing. When possible, adding the mother or another grandparent can further strengthen the results.
DNA collection kits are shipped free via trackable USPS delivery to addresses within the contiguous United States, and each kit includes a prepaid return envelope for sending samples back to the laboratory. Expedited shipping options are available during checkout for physical addresses within the contiguous U.S. If needed, participants may also choose the “Make Your Own Kit” option and submit samples using their own collection materials.
Results are typically available within 2–3 business days after the laboratory receives all samples. Orders placed before 12:00 PM (EST) Monday through Friday are generally shipped the same business day, which helps minimize overall turnaround time.
Our laboratory performs a high volume of relationship DNA testing, which allows us to offer competitive pricing while maintaining accredited laboratory standards. Tests are conducted using validated methods, including advanced 46-marker analysis, to ensure accurate and reliable results without compromising quality.
Relational DNA testing is an indirect comparison, so additional genetic information can improve the strength of the results. Including the mother allows her genetic contribution to be identified and excluded, helping isolate the biological line being evaluated. Testing both grandparents, when available, can also increase statistical confidence. While these additions are helpful, a 46-marker test can still provide strong results when only one grandparent and the child are available.
Home Grandparent DNA Test Reviews
For over 25 years, families across the United States have relied on our DNA testing for accurate results and dependable service.
“In my opinion I am very satisfied. I have an adult daughter that’s 24 years old now that I did not know I had. The results came in very quickly, took a couple of days, and I am very pleased with this product. If I need it again, this is what I’ll get. I will definitely recommend this to anybody that needs to do a DNA test.”
