MAIL-IN SELF-COLLECTION KIT
Not for court useGrandparent DNA Test — Informational
We understand this is a sensitive family situation. Every kit is handled with complete discretion and care.
When the alleged father has passed away, is unavailable, or refuses to participate, a grandparent DNA test can establish the biological connection between a child and the paternal grandparents. The informational test is a flat-price mail-in kit — we ship self-collection materials, each person provides a simple cheek swab at home, and samples are mailed back to the lab. Results are private and for personal peace of mind only — not formatted for court use. If you need legally admissible results, see our Legal Grandparent DNA Test.

Frequently Asked Questions
Is the test more accurate with one grandparent or both?
Accuracy improves significantly when both grandparents participate. Testing one grandparent can still provide useful information, but including both gives the laboratory more genetic markers to compare and produces a clearer probability statement.
Can this be used if the alleged father is deceased or unavailable?
Yes — that is one of the most common reasons people choose grandparent testing. Comparing the child's DNA with the paternal grandparents can establish a biological link when the father cannot be tested directly.
How accurate is a grandparent DNA test?
Grandparent testing is generally less definitive than a direct parent-child test. Results include a clear probability statement. Including both grandparents — and, when available, the connecting parent — strengthens the analysis.
Is this test confidential?
Completely. Results are delivered only to you, never shared with third parties.
What's the difference between informational and legal grandparent testing?
Informational testing is mail-in and private, for personal knowledge only. Legal testing requires supervised, chain-of-custody collection with photo ID verification and produces court-admissible results. See the Legal Grandparent DNA Test page if you need results for a legal proceeding.
Do we need a doctor's referral?
No. You can order this test directly — no doctor's order, no referral, and no insurance required.
