Non-legal tests are for personal knowledge, not court use. Legal tests use verified identity and documented chain of custody to support court use when applicable requirements are met.
Paternity DNA Testing
Establish or confirm a biological father-child relationship with a straightforward cheek-swab collection.
Painless buccal (cheek swab) collection for adults and children
Available as a private/informational test or as a legal chain of custody collection
Alleged father and child; mother's participation optional but recommended
Available as a legal chain of custody collection. Laboratory analysis for legal testing is performed by our AABB-accredited laboratory partner.
Same laboratory analysis, but participants are not formally identity-verified, so the results are for personal knowledge only and cannot be used in court.
Legal chain of custody
Identity is verified and documented at collection, and specimens stay in a controlled, witnessed chain — the standard required for child support, custody, immigration, estate, and other official matters.
Legal, court-admissible chain-of-custody DNA testing in Allen and Collin County
When DNA results will be presented to a court, a child support office, an immigration authority, or an estate attorney, the collection itself must be documented. For those cases LegacyLink performs a legal chain-of-custody collection: each participant is identified with government-issued photo ID, photographed, and swabbed by a trained collector, and the specimens are sealed in tamper-evident packaging with signed custody paperwork. Legal DNA testing is coordinated through our AABB-accredited laboratory partner, which performs all laboratory analysis and issues the official report. LegacyLink Testing & Compliance Services LLC is an independent specimen collection and testing coordination company and is not itself AABB accredited.
Relationship DNA testing when the alleged father cannot be tested
Paternity is not the only way to answer a family question. Sibling, grandparent, and aunt/uncle (avuncular) testing compare a child with other close biological relatives when the alleged father is unavailable, deceased, or unwilling to participate. Each of these relationship tests is available as an informational test for personal knowledge or as a documented legal collection. You can review current test pricing, read the frequently asked questions, or request an appointment.
Service area: DFW direct collection and nationwide coordination
DFW direct collection: collections take place by appointment in our Allen, Texas office, or we travel to you. Mobile DNA collection covers Plano, McKinney, Frisco, Richardson, Wylie, Sachse, Murphy, Prosper, Garland, and the wider Collin County and Dallas-Fort Worth area, including homes, offices, hospitals, attorney offices, and care facilities.
Nationwide coordinated collection: for clients outside DFW, LegacyLink coordinates DNA testing through Universal Forensics and partner affiliate collection facilities across the United States. Those collections are performed by the partner facility, not directly by LegacyLink. Learn more about how we work.
