At-Home Grandparent DNA Test Kits by Mail

When a biological parent cannot take part, a grandparent may provide useful DNA evidence about the family connection. Grandparent testing can be used on the maternal or paternal side and can include one or both biological parents of the unavailable parent.

The standard test uses painless cheek swabs collected at home. Our AABB-accredited U.S. laboratory partner compares 46 DNA genetic markers plus Amelogenin. Required samples are dual processed before results are released, and standard results are typically ready within 2 to 3 business days after the complete case enters laboratory processing.

Grandparentage is an indirect relationship test, so the report explains how strongly the available DNA supports the proposed grandparent-grandchild relationship.

When a Grandparent DNA Test Can Help

Families commonly choose this test when:

• A possible biological parent is deceased or unavailable for direct testing.

• A grandparent and grandchild reconnect after adoption or a long separation.

• Family or agency records leave a specific biological connection uncertain.

• Relatives want private clarification of a maternal-side or paternal-side relationship.

If the connecting parent can provide DNA, a direct paternity or maternity test is usually the clearer option.

Do You Need One Grandparent or Both?

One alleged grandparent and one grandchild can be tested. If both biological grandparents from the same side of the family are available, including both gives the laboratory more genetic information and may strengthen the analysis.

The child's known parent may also help in some cases. For a paternal-side comparison, including the child's known mother can help the laboratory account for the maternal DNA already present in the child.

These extra participants are helpful in certain family structures, but they are not required in every case. Tell us who is available and we will help you decide whose sample is worth including.

Standard, Multi-Location, or DIY Grandparent Testing

• Use the standard at-home kit when the grandparent and grandchild can collect from the same location.

• Use the multi-location kit when the participants live at two different U.S. addresses.

• Use the DIY digital test when you want the instructions electronically and will provide the approved supplies.

An approved personal item may sometimes be used if a cheek swab is unavailable. Alternative samples must first produce a usable DNA profile, so contact us before sending an item that is unusual, old, or difficult to replace.

How Grandparent DNA Testing Works

1. Identify the maternal or paternal family line being investigated.

2. Decide which grandparent, grandchild, and known parent samples will be included.

3. Collect, label, and return each sample with the required forms.

4. Receive the completed relationship report privately by email.

An inconclusive result is possible when the participants do not provide enough genetic information to separate the proposed relationships clearly. Another grandparent, the connecting parent, or a different close relative may help if more testing is needed.

What If Another Relative Is Available?

Grandparent testing is one possible route when a parent cannot participate. A sibling DNA test may be a better fit if a known biological child of the unavailable parent can provide DNA. An aunt or uncle DNA test may fit when the unavailable parent's biological sibling can participate.

There is no single best substitute for every family. We look at the available relatives and help you choose the comparison that makes the most sense for your situation.

Personal Results and Legal Grandparent Testing

A self-collected grandparent test is for personal knowledge. Official use requires verified identity, witnessed collection, and documented chain of custody. Review our legal DNA testing options before collecting samples if the result may be needed for court, immigration, inheritance, Social Security, or another official matter.

If several relatives could take part, contact My Forever DNA before ordering. We will help you build the case around the family members who are actually available.

My Forever DNA does not currently ship self-collected at-home DNA test kits to New York addresses.
