Frequently Asked Questions: Grandparent DNA Testing in Washington
What Is the Cost of Legal Grandparent DNA Testing in Washington?
Legal grandparent DNA tests in Washington usually cost between $400 and $499, depending on laboratory fees and optional expedited services. For at-home options, the price is typically lower.
Who Needs to Be Tested for a Grandparent DNA Analysis?
Testing typically requires the child and one or both grandparents. Including the biological mother’s DNA sample can significantly increase the accuracy of the results. For legal purposes, strict chain-of-custody procedures must be followed. Learn more about legal parentage procedures at the Washington State Department of Health.
Can Grandparents Use DNA Testing for Immigration in Washington?
Yes, DNA testing is frequently used in immigration cases when direct parentage testing is not possible. Accredited labs meet USCIS requirements.
How Accurate Is Grandparent DNA Testing?
Results are highly reliable—especially when samples from both grandparents or the mother are included. Tests provide a percentage probability of relationship rather than a definitive "yes/no" answer.
What Happens If My Grandparent DNA Test Results Are Inconclusive?
Inconclusive results may occur if insufficient genetic markers are detected. Adding the other grandparent or the mother’s sample can help clarify outcomes.
How Long Does It Take to Get DNA Test Results in Washington?
Typically, results are available in five business days after samples reach the lab. Expedited results may be possible for an additional fee.
Can a Grandparent Request a DNA Test Without the Parent’s Consent in Washington?
In legal cases, parental consent may be required depending on Washington state law. At-home tests may not need parental permission but results from them are inadmissible in court. Validate current legal requirements with the Washington State Department of Health and DSHS Voluntary Paternity Testing FAQ.
