Our 34 marker grandparent DNA test analyzes 24–34 markers, and is a great option when the mom is available for test, and can help save you money.

Unlike many low-cost DNA tests that analyze only 20–22 genetic markers, our enhanced grandparent DNA test examines 24–34 markers. This helps provide a significantly greater statistical conclusiveness when trying to verify if a grandchild / grandparent relationship exists. Testing more markers can dramatically increase the chances of a more clear & conclusive result.  This is important when families need answers they can trust.

This test is especially powerful when the mother is included, as maternal participation further refines the analysis and improves accuracy. However, even when only a grandparent and grandchild are tested, our expanded 34 marker analysis still exceeds what most competitors offer.

Rest assured your privacy is treated with the same level of care as your results. PaternityUSA does not sell, share your DNA data, and all samples are handled under strict privacy protocols.

All tests are performed in an certified accredited USA lab, thus ensuring compliance with American quality standards and privacy protections. Unlike many online major marketplace providers, your DNA is never sent out of the country for testing.

Typically, results are available within 2–3 business days after receipt in lab, therefore your answers are delivered quickly without delays.

This grandparent DNA test can be, and often is, performed even if the mom is not available.

At $175, our 46-marker grandparent DNA test delivers one of the best value-to-accuracy ratios available for advanced relationship testing—without compromising scientific rigor, laboratory standards, or privacy.

Unlike many so-called “expanded” tests, this is a true 46-marker analysis, meaning all 46 genetic markers are examined in every case. Analyzing a higher number of markers substantially increases the statistical strength of grandparentage testing, which is especially important when one or both parents are unavailable for testing.

By evaluating nearly twice the number of markers compared to standard 20–22 marker tests, this enhanced approach significantly improves the likelihood of obtaining a clear and conclusive result, helping reduce uncertainty and the need for retesting. More markers provide more data points, allowing for stronger probability calculations and greater confidence in the outcome.

All samples are processed using validated laboratory methods in accredited U.S. facilities, ensuring consistent quality control, secure handling, and reliable results. Your personal and genetic information is treated with strict confidentiality and is never sold, shared, or placed into external databases.

Once testing begins, results are typically available within 2–3 business days, combining advanced analysis with a fast and dependable turnaround—so you can receive accurate answers without unnecessary delays.
