DNA Testing Lewisville TX


Types of DNA Tests at our Lewisville TX clinics:

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 Lewisville DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Facts about DNA Testing in Lewisville TX


DNA Affects Family Law in Lewisville

All kinds of families live in Lewisville to take advantage of the green space, amazing schools, and close neighborhood feel. When a baby is born to parents that are not married, Texas law decrees that both of the parents must sign an Acknowledgement of Paternity, which gives the presumptive father legal rights to his child. If paternity is in question or the parents disagree on the parentage of the child, a paternity DNA test can be ordered. This involves the Office of the Attorney General filing "a petition asking that the court establish an alleged father as the biological father."

Experts Serving the Lewisville Area Discuss How DNA Affects Child Support

In Texas, if a father refuses to comply with a court-ordered paternity test, he can be held in contempt of court, which may result in anything from fines to jail time. According to local law firm Helene Parker & Associates, if the two parties in a child custody or paternity dispute "attempt to go at it alone, what would otherwise be a relatively simple matter can turn into a nightmare of uncertainties, lots of questions, disagreements, and red tape."

For many Lewisville families who are prioritizing their child's safety and stability, a DNA test can resolve a lot of questions and help out in situations involving custody, visitation, and support. These tests are quick and easy, and can even be done on grandparents if the father's DNA is not available.
