What is a Legal Grandparent DNA Test?
A legal grandparent DNA test compares a child’s DNA with one or both grandparents to help determine a biological relationship when a parent isn’t available for testing. Results are issued with chain-of-custody documentation.
When is a Grandparent DNA Test needed?
It’s commonly used when an alleged parent cannot be tested (unavailable or deceased) and you still need relationship testing. It may be requested for legal, custody, inheritance, or agency documentation needs.
Is the test court-admissible?
If you select the legal (chain-of-custody) option and all parties follow the required ID and collection steps, the report is typically accepted for court or agency use. Acceptance can vary by jurisdiction and case requirements.
How is the test performed?
Samples are collected by an approved collector with ID verification and documented chain of custody. The lab then analyzes the samples and issues a signed report.
How accurate is the Grandparent DNA Test?
Grandparent testing is highly reliable when the right participants are tested (one vs. two grandparents can affect strength of results). Your report will include a clear probability statement based on the samples provided.
How long does it take to get the results?
Turnaround time depends on the test type and when samples arrive at the lab. Most results are available within a few business days after the lab receives all required samples.
