DNA Testing Services in San Antonio TX


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

Facts about DNA Testing in San Antonio TX


Paternity Testing Survey of San Antonio Residents

In order to better understand San Antonio residents need for DNA testing, Health Street surveyed local residents about their experiences. We found that 33 percent of kids in the city are being raised in single parent homes, and we wondered if that had an impact on the rate of paternity testing. Health Street offers DNA tests at three clinics in San Antonio, and yet, we found that one out of every three people waited over ten years to get a DNA test after identifying a need for it.

Quotes from Survey Respondents

Quotes from DNA StudySan Antonio Residents Said:
"I do not want to cause problems with people in my mother's biological family."

"I think it's pretty expensive, and have not really had the time and patience to really look into it."

"It's been holding me back for 10 years. The reason I have not committed to it is because I don't want to cause distress in my sibling, who will always be my sibling [regardless]. Too many odd stories, and lack of traits being shared. I don't want to cause heartache with my long time speculations. What if I am wrong? Not only [will] I have offended my mother but I will severely hurt my sibling, who has no doubt of his blood relation [with] our family."
About this Study: Health Street surveyed San Antonio residents about the personal side of DNA testing.

In San Antonio, DNA Testing Brings Families Together

In San Antonio, DNA testing isn't just about parents and their children. It can also bring families together. Recently, a heartwarming story from News 4 San Antonio profiled a man who flew from Milwaukee to San Antonio at Thanksgiving to meet five sisters he never knew he had. Through DNA testing, he was able to not just identify his father, but also his father's five daughters who are now his beloved sisters.

The newly-reunited siblings were able to celebrate the holidays together for the first time in 2019. As the story clearly illustrates, DNA testing isn't just about discovering one's heritage. It also helps to unite families and bring clarity to situations where paternity is in question.

Military Families Have Unique Family Law and DNA Testing Needs

Military parents undergoing DNA testing may need a lawyer with specialized knowledge. The large military presence in San Antonio has meant that local family lawyers need to be well-educated on the unique needs of this community. According to local family law attorney Mysti Murphy, "military divorce and family law cases may involve unique legal issues that are lacking in cases involving civilians. Most commonly, these cases involve challenging jurisdictional issues."

There are more than 80,000 individuals currently employed in the defense industry in San Antonio and the surrounding areas, and more than 250,000 who are veterans. Whether they serve in the Marines, Coast Guard, Air Force or Army, military parents and their spouses who are undergoing DNA paternity testing in San Antonio need to be aware that their case may be legally more complex than family law issues for civilians.

Child Support Court - Bexar County

San Antonio, a major city in Texas, has a culture that deeply emphasizes family values. The Children's Court Division and Child Support Court in Bexar County makes a concerted effort to ensure that children are raised by both parents whenever possible, so long as it doesn't put a child in harm's way. In Texas, "harm" can be defined from something as simple as parental incompetence to something as dangerous as domestic violence. If the children are old enough, the court will consider the children's stated preferences and testimony. In Texas, the term "Conservator" is used rather than "Custodian". If one parent is coined "Conservator", that parent is in charge of all the major decisions that impact the child, such as health care and education.
