DNA Test - Garland, Texas

Garland TX DNA Testing Locations

Types of DNA Tests at our Garland, 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 Garland DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Garland, Texas - DNA Testing

Establishing paternity in Garland, TX

Establishing paternity is one of the most significant steps in the child support process, and for unmarried couples, it is necessary to establish paternity for multiple reasons. For example, the biological father has no legal rights or responsibilities toward the child unless the parentage is established.

In Texas, there are two common ways of establishing paternity. If parents agree about paternity, they can sign a Voluntary Acknowledgment of Paternity. If parents doubt who the birth father is or if they do not cooperate, then the court can establish paternity. Establishing paternity through the court usually involves a DNA test to prove who the biological father is. Once the tests are back, the judge can finalize the order.

Texas siblings reunited after 70 years thanks to a DNA test

Dennis and Doug were twins who were adopted when they were three. The boys knew they had a biological sister, but it took them 70 years to find her. Eventually, Dennis took a DNA test, which suggested a match with his cousin.

From the cousin, Dennis got Connie's number and texted her. He said that he knows he has a sister and wanted to know if she happens to be her. When Connie received the text, she had to pull over. She has been searching for her brothers, too, so this was not a shock but a pleasant surprise! There was a surprise for Dennis, too. Connie told him he had another half-sister.

All this time, they lived just one hour away from each other. Unfortunately, Doug passed away, and their biological mother died, but Connie and Dennis reunited and shared their life journeys. They could not be happier that they found each other even after so many years and agreed it was a miracle.
