What Is the Difference Between a Legal DNA Test and a Peace-of-Mind Test in Texas?
A legal DNA test follows strict AABB-certified chain-of-custody protocols, requiring government photo ID verification and professional cheek swabbing, producing a certified laboratory report legally admissible in Texas family courts for child support and custody. A peace-of-mind DNA test provides private answers without formal chain-of-custody and cannot be used in court proceedings.

DNA Testing Frequently Asked Questions
How much does a legal DNA paternity test cost in Marshall, TX?
Our legal court-admissible DNA paternity test is $425 all-in, covering sample collection, AABB partner lab analysis, and notarized court reports. Private peace-of-mind tests are $325.
What should I bring to a legal DNA appointment?
Adult participants must bring a government-issued photo ID (driver’s license, passport, or state ID). For minor children, bring a birth certificate or hospital record if available.
Can testing be done if the mother or father lives in another state?
Yes. We coordinate out-of-state collections through our network of AABB-accredited collection sites across the United States, linking both samples seamlessly at the lab.
How accurate are your DNA paternity test results?
All testing yields a 99.99%+ probability of paternity for inclusions, or 100% certainty for exclusions, analyzed by our AABB-accredited partner laboratory.
Is a mother’s sample required for a paternity test?
No. A mother’s sample is recommended when available, but a definitive court-admissible result can be achieved testing only the alleged father and child.
