DNA Test - Harlingen, Texas

Harlingen TX DNA Testing Locations

Types of DNA Tests at our Harlingen, 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 Harlingen DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Paternity Programs in Harlingen, TX

The Office of Vital Statistics offers Harlingen residents access to the Paternity Registry program as a means to preserve the paternal rights of Texas fathers. Though registering with the program does not establish legal paternity in the state of Texas, it does help protect the rights of Harlingen men who believe they have fathered a child but are not listed on the birth certificate as the father.

Harlingen fathers often use this registry if the mother of a child refuses to establish paternity or when more than one man is claiming paternity. Through proper registration, Harlingen fathers assume responsibility for children they believe they have fathered, which can be beneficial in court when looking to gain custody, establish paternity, or halt a movement for adoption.

Navigating Paternity Establishments in Harlingen, TX

If two Harlingen parents are not married at the time of their child's birth, paternity must be established for the father to obtain parental rights and to have his name placed on the child's birth certificate. Luckily, Texas makes it easy to establish paternity, which can be done simply by filing an Acknowledgment of Paternity (AOP) through an AOP-certified state entity.

Bear in mind that both parents must be in agreement regarding a child's paternity before signing an acknowledgment. If either Harlingen parent refuses to establish paternity, they will need to file a petition through Cameron County Court to initiate a court-ordered establishment. In these cases, a judge mandates court-ordered DNA paternity testing to accurately determine the father to complete the proper establishment of paternity as well as any child support orders.

Noting the Importance of DNA Testing in Harlingen, TX

After the birth of a child, Harlingen parents can be quick to establish paternity out of excitement, even if they have not gained full confidence in the given paternity claim. Once paternity is legally established, the assumed father will incur paternal responsibilities, which often include monthly child support obligations.

In the event that mistaken paternity is learned down the line, the previously assumed father will still be required to make monthly payments, regardless of him knowing that he's not the biological father, until paternity is disestablished. To avoid these legal frustrations, Harlingen parents must first seek DNA testing if there is any chance more than one man could be the biological father.
