DNA Testing in Dallas, TX

You can test at GameDay DNA collection sites or use an at‑home cheek‑swab kit for private peace of mind. For court or child‑support cases, many families work with the Texas Office of the Attorney General (OAG) Child Support Division, and state resources such as Paternity – Texas Access explain that when parents do not agree, a paternity petition can be filed and the OAG can help by requesting DNA testing, while Texas family‑law explainers on DNA paternity testing in Texas note that OAG‑requested tests are typically arranged through accredited labs and used to set support and visitation orders.

Texas follows the Uniform Parentage Act in chapter 160 of the Family Code, which details when and how courts can order genetic testing. The Texas State Law Library’s paternity guide and practice summaries like Paternity Defined – Texas Family Code explain that when a party files a parentage case, the court will generally order DNA testing under Family Code provisions such as section 160.502, and that a man identified as the father under section 160.505—typically by tests showing at least a 99% probability—must be adjudicated the legal father unless other admissible test results rebut that finding.

Most legal paternity tests in Texas use buccal‑swab (cheek‑swab) DNA samples from the child and the alleged father, and often the mother. Texas family‑law firms describing court‑ordered paternity tests and DNA paternity testing in Texas explain that accredited labs collect DNA by gently swabbing the inside of each person’s cheek and that in Texas a man is generally presumed to be the father if genetic testing shows at least a 99% probability of paternity, with results typically available in a few weeks.

For at‑home kits, use the sterile swabs in your kit, rub firmly along the inside of each cheek for the full time listed in the instructions, let the swabs air‑dry, and seal them in labeled envelopes before mailing. Texas‑focused guides on DNA paternity testing in Texas and how DNA testing impacts family law cases in Texas note that both private and court‑ordered tests rely on cheek‑swab DNA, but only chain‑of‑custody collections performed by accredited labs and ordered or accepted by a court or the OAG Child Support Division can be used as legal proof in custody and support cases.

GameDay DNA provides results by secure online portal or encrypted email, with printed reports available for legal tests. When the OAG’s Child Support Division is involved, Texas paternity resources such as Paternity – Texas Access and law‑firm explainers on establishing paternity in Texas describe how the OAG or court orders the DNA test, receives the certified lab report, and then uses those results at a hearing or in an agreed order to establish paternity and enter child‑support and visitation provisions, with parents notified through official court documents or OAG correspondence.

Yes—Texas statutes specifically address the role of genetic testing in parentage cases. Commentaries on Paternity Defined – Texas Family Code and federal summaries of Texas law on genetic testing explain that under the Uniform Parentage Act, admissible genetic‑test results identifying a man as the father under section 160.505 require the court to adjudicate him as the father, while exclusionary results require the court to adjudicate that he is not the father, and that even inconclusive tests may still be considered together with other evidence to decide paternity.

Either parent, the child (through a representative), or the state (through the OAG) may be involved in bringing a paternity case in Texas. The Texas State Law Library’s paternity guide and TexasLawHelp’s step‑by‑step article I need a paternity order explain that a child’s mother, a man who believes he is or is not the father, or the OAG can file to ask the court to decide paternity, and that the resulting paternity order can include custody, visitation, and child‑support provisions along with any court‑ordered genetic testing required to resolve the case.

In special situations—such as when an alleged father has died or is unavailable—Texas courts can still use genetic evidence and other proof to decide parentage. Social Security’s analysis of Texas law on genetic testing and inheritance notes that under the Texas Family Code, courts may order genetic testing of a deceased individual or close relatives and may rely on compliant test results, together with other evidence, to adjudicate paternity for purposes such as intestate inheritance, and that in some cases courts have accepted grandparent DNA testing as part of the proof needed to establish a parent‑child relationship.
