Paternity Testing in Denton, Texas

There are several types of DNA testing services that are offered at our Denton testing centers to validate close family relationships. The most commonly ordered DNA test is a legal paternity test to conclusively establish whether or not a man is the biological father of a child. Health Street’s 21 marker DNA paternity testing is the state of the art. Our paternity test results are statistically conclusive at the rate of 99.9% or greater.

Other DNA Tests

Relationship Tests to validate grandparent to grandchild, siblings, half-siblings, aunts, and uncles:

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)

DNA tests such as sibling or avuncular studies, can sometimes come back with a result of less than 95% certainty. This is normal, especially if only two parties participate in the test. Adding an additional close relative to the test helps us learn more about the family’s DNA composition and typically leads to a more conclusive result.

Specimens we can test for DNA

The easiest and most reliable way to perform a genetic sample collection for a paternity test is by a swab of the inner cheeks. These skin cells, known as buccal cells, rub off easily onto cotton swabs and remain in place, to be extracted by our testing laboratories for analysis.

Other specimens, such as hair follicles, fingernails, and garments that might contain someone’s DNA, can also undergo lab testing to see if there is a match. These non-standard DNA tests are done by registering online for an Alternative Specimen DNA Test (Nails, Teeth, Fabric). Once registered, you ship the DNA sample to our lab. We’ll attempt to extract the DNA and compare it to a cheek swab of the other party.

Legal DNA Tests vs. “Peace of Mind” At-Home Tests

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 to hold up in court, the DNA specimen must be collected at a clinic using strict chain of custody procedures. The DNA testing technicians at our Denton test centers are trained to follow guidelines that ensure that the results can be used for legal purposes.

The results of our legal DNA tests can be used for any legal purpose:

to change the name on a birth certificate
to petition for child support
to petition for survivor benefits
for child custody arrangements
to alter inheritance procedures or wills

Home tests offer more flexibility:

Home DNA tests are specimens containing DNA (or possible DNA) that are shipped to us for analysis. The results of these home tests cannot be used in court (since there is no way to prove whose specimens were actually sent). However, the tests are just as accurate and can provide peace of mind. At-home DNA tests also offer a lot more flexibility.

In addition to commonly mailed in DNA specimens like hair follicles, we can also extract DNA from other bodily fluids. We can even try and lift the DNA left on items like clothing, a toothbrush, or a straw. If we can get the DNA from the alternative item, we can then compare it to another person to see if they are related. Some examples include:

Stained garments
Mucus and other bodily fluids
Soda cans
Chewing gum

How to schedule a DNA Test in Denton TX

Scheduling a DNA test at one of our Denton clinics is simple and fast, and we often have appointments available in the same week, though it’s always helpful to schedule in advance to make sure you get the time you want. We have clinics in Denton, plus many more throughout Texas and across the United States. During registration, we’ll show you the nearest locations so you can choose the one that’s most convenient. You’ll pick the times and days that you prefer.

You can set up separate appointments for each of the people being tested, either at the same location or at different locations. You’ll get an email and text message with your appointment information. There is no fee if you need to change the time or location of a DNA test appointment at any time.

How long it takes to get results of a DNA test

Paternity tests conducted at one of our Denton facilities typically take about a week to come back. Other relationship tests, such as sibling studies, can take a few days longer to come back. When the results are ready, you are notified immediately via email. Then, the hard copies of the paperwork are sent afterward via regular mail.

The DNA test appointment – what to expect and what to bring

The appointment itself only takes about 15 minutes. The specimen collection process is a simple and painless cheek swab. No needles are used. When you’re being tested at our Denton clinic, you’ll be asked to provide fingerprints and to show photo identification. We’ll also take pictures of the people being tested so that the final report will include legal assurances of who was actually tested.

For infants, hospital discharge papers qualify as identification. Otherwise, a birth certificate or social security card can be used as ID for a child. No other preparations are required for this appointment.

Does the mother need to be present at a paternity test?

If a man is considered the legal father of a child, then the mother does not have to be present or give consent for paternity testing. However, if he is not currently considered the legal father, then he cannot sign for the child. Therefore, the mother does need to be there. If neither parent is available, other legal guardians can bring the child so long as they have the right to make medical decisions on the child’s behalf.

DNA testing if one party is not in Denton

The two parties testing (for example: father and child) do not have to be tested at the same time or even at the same location. We have many clinics across Texas as well as nationwide, so we can test one party in Denton and the other party anywhere else in the USA. The specimens are then matched up in the lab for analysis.

Laboratory certifications

Health Street works strictly with AABB Certified labs for DNA testing. All specimens that are collected in Denton or elsewhere are shipped securely from our testing locations to a nationally certified laboratory.

Proving Paternity for Child Custody Purposes in Denton

In Texas, if a child is born to unmarried parents, state law doesn’t recognize the biological father as a legal parent. If you live in Denton and want to establish paternity for a child, you can do it voluntarily through the Acknowledgement of Paternity (AOP) form by working with an AOP-certified organization at the hospital, vital statistics office, or Office of the Attorney General, located at 1808 Cornell Lane in Denton.

You can also have an agreed paternity order which establishes a legal father for the child. Parents agree voluntarily on custody, visitation, child support and medical support. The order can be filed with the Denton County Child Support Office, also located at 1808 Cornell Lane. A DNA Paternity Test can prove paternity with 99% accuracy according to the Texas Attorney General’s office.

Local DNA Stories

A Denton County father, Chris Clay, set a precedent in Texas child custody cases in June 2020 when the state Supreme Court ruled that a Denton County judge had violated his rights in an earlier custody decision. Chris and Arli Jackson Wilkes were the unmarried parents of Abigail, born in 2014. The couple shared custody without incident after the relationship broke up in 2016.

Arli later moved in with another boyfriend and lived with him and her daughter Abigail until she died in a car accident in 2018. Arli’s parents and her boyfriend filed for custody of Abigail after her untimely death. The Denton County court initially ruled that the boyfriend had visitation rights with Abigail, although her mother had died and he had no biological relationship with the little girl.

Experts Say

Chris Clay’s attorney, Holly Draper, said that Texas state law makes it “difficult for family members to file for custody,” but ironically — until this decision — it was “much easier for non-relatives.” The June 2020 Texas Supreme Court decision makes it more difficult for non-biological relatives or even family friends to file for custody of a child after a parent dies.
