DNA Test - Nacogdoches, Texas

Nacogdoches TX DNA Testing Locations

Types of DNA Tests at our Nacogdoches, Texas clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

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 alleged father and child or children. 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 ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. 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. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Nacogdoches DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Benefits of Establishing Paternity in Nacogdoches, TX

Establishing paternity benefits both parents and the child. By having a legal father, a child can develop connections with both parents, and the father can have his name on the birth certificate. Legal paternity also gives the child access to medical records from both families, and benefits, like life insurance, social security, veteran's benefits, and medical coverage. Parents must also establish paternity before seeking custody, visitation, and child support.

Establishing Paternity in Nacogdoches, TX

In Nacogdoches, if two parents are married, the husband is the child's legal father. However, unmarried parents must establish paternity. The easiest way to establish paternity in Nacogdoches is by signing an Acknowledgment of Paternity, a voluntary legal form parents can sign as long as they agree on paternity. If the parents cannot agree to sign the voluntary form, they can establish paternity in court through the OAG Child Support Division, by hiring a private attorney, or by filing a lawsuit in court. The local child support office is located at 2015 N. Stallings Dr. in Nacogdoches.

Proving Paternity for Child Custody Purposes in Nacogdoches, TX

Nacogdoches parents can use DNA (paternity) testing to prove that an alleged father is the child's biological father. Parents can take a DNA test before signing an Acknowledgment of Paternity or, if establishing paternity in court, a judge may require a DNA test to use as evidence. If the alleged father denies paternity, the OAG's Child Support Division can order a DNA test to prove paternity. DNA testing is simple and reliable and can exclude a man as the child's father or determine the probability of fatherhood by more than 99%. DNA test samples are generally taken by cheek swabs of the father and child and sent to a certified laboratory for testing. Results from DNA home test kits are not admissible in court.
