DNA Test - Galveston, Texas

Galveston TX DNA Testing Locations

Types of DNA Tests at our Galveston, Texas locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the people being tested. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory. Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.

When deciding which type of DNA test is right for you, consider first what you might do with the results. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Galveston DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Resources for Galveston Residents Navigating Paternity Issues

If issues relating to child support arise, Galveston parents have local resources that can help them to navigate legal processes. The La Marque Child Support & Social Service Office, which is located in nearby Sante Fe, Texas, can answer questions regarding child support filing and support services, paternity tests and child support enforcement. This government agency oversees child support issues for Galveston County residents. If a paternity case goes to court, it will be heard by the Family Section of the Galveston County District Court. This legal body manages child support and child custody cases, in addition to adoption cases and divorces.

Proving Paternity for Child Custody Purposes in Galveston, TX

In Galveston, TX, if a child is born to married parents, the husband is automatically the child's legal father. However, if a child is born out of wedlock, Galveston parents must establish paternity for the child to have a legal father. Parents can establish paternity voluntarily as long as both parents agree to sign an Acknowledgment of Paternity form. But if either parent questions paternity, they can take a DNA test to determine the child's biological father before completing the voluntary acknowledgment form. If the mother and alleged father cannot agree to establish paternity voluntarily, they'll go to court, and the judge will likely order a DNA test.

Experts Say...

Galveston County paternity attorney Daniel R. Bacalis, P.C. states the importance of the parent-child relationship, and why it's essential to establish paternity, especially if the parents are not married. He says, "If one or both parents are unwilling to voluntarily acknowledge paternity, or if either party is uncertain about the identity of a child's biological father, the mother, the presumed father, the alleged biological father, or other parties may file a petition to adjudicate paternity in family court." The judge will typically order DNA tests to confirm that the man is the biological father. Lori Elaine Laird, an attorney that serves Galveston, TX, explains the importance of establishing paternity. She said that establishing paternity allows the parents to receive visitation, custody, and child support orders. "The father may be able to provide health insurance or other benefits for the child once paternity is established," Laird added. "The child may be able to receive money through a government program. In many cases, the child may be eligible for Social Security, veteran's benefits, health care, or other government benefits."
