TestMark DNA's Brownsville, Texas collection site is at 864 Central Boulevard, Suite 900, in the Central Diagnostic Clinic building next to Valley Baptist Medical Center. It is one of only two TestMark DNA sites in Cameron County; the other is in Harlingen.

Next to Valley Baptist Medical Center stands the Central Diagnostic Clinic, or CDC, building at 864 Central Boulevard, a multi-tenant medical office building, and TestMark DNA's Brownsville collection site is in its Suite 900. The hospital, whose address is 1040 West Jefferson Street, is the easiest landmark to steer toward. Inside, the building has a central waiting area with skylights and offices that look out over a resaca. Valley Doctors Clinic is one of the other practices here, in Suite 2500. Central Boulevard out front is U.S. 77 Business, and for DNA testing in Brownsville, Texas, the CDC building beside the hospital is the place to go.

Brownsville Metro's Route 2, Jefferson and Central, runs along Central Boulevard and lists Valley Baptist Medical Center among its stops, so the bus reaches the hospital next door. Cameron County has only two TestMark DNA sites, this one and another in Harlingen. San Benito, Los Fresnos, Port Isabel and Rancho Viejo have none of their own. For a county case, filings go to the Cameron County District Clerk in the Judicial Building at 974 East Harrison Street, and the Attorney General's Brownsville child support office is at 1655 Ruben Torres Boulevard.

In Brownsville, TestMark DNA is in the Central Diagnostic Clinic building on Central Boulevard, next to Valley Baptist Medical Center.

DNA testing requirements in Texas

Texas does not require a prescription or doctor's order for a DNA paternity test. Paternity in Texas is established either by both parents voluntarily signing an Acknowledgment of Paternity (AOP), which carries the same legal effect as a court order, or through court-ordered genetic testing under the Texas Family Code when parentage is disputed. For results to be used in a Texas court, the test must be performed at an accredited laboratory with a completed chain-of-custody form, which means samples have to be collected at a certified site rather than at home. A home test answers the question for your own peace of mind but will not be accepted for child support, custody or a birth certificate change. If you are not sure which one your situation calls for, call and we will walk you through it.

What to Expect at Your Appointment

DNA testing at our Brownsville, Texas collection site is straightforward, painless, and typically takes less than 30 minutes. Here is what to know before you visit 864 Central Blvd Ste 900.

Bring a Government-Issued ID

Adults bring a driver's license, state ID, or passport. Children under 18 do not need ID. A birth certificate is helpful for legal tests but not required for personal tests.

The Sample Is a Painless Cheek Swab

Collection takes about a minute. A trained technician rubs a soft cotton swab on the inside of the cheek for each tested party. No needles, no blood, no fasting required.

Plan for 15–30 Minutes on Site

Most visits to 864 Central Blvd Ste 900 in Brownsville take under 30 minutes from check-in through sample collection, including the chain-of-custody paperwork completed in person.

Your Collection Is Scheduled by TestMark DNA

Children Can Be Tested at Any Age

Infants, toddlers, and minors are all eligible. The cheek swab is the same regardless of age. For legal tests involving a minor, the custodial parent or legal guardian must be present to sign the chain-of-custody form.

Results Arrive in 3–5 Business Days

Once all samples are received at the accredited laboratory, standard turnaround is 3 to 5 business days. Results are delivered confidentially by encrypted email or secure portal. They are never released over the phone.

Pricing & Payment

DNA test pricing in Brownsville, Texas depends on the specific test you need. Call TestMark DNA for a free consultation. We will confirm the exact price for your situation before you visit the collection site.

Pricing Varies by Test Type

Paternity, maternity, sibling, grandparent, immigration, and home kit tests are each priced differently. Legal (court-admissible) tests cost more than personal-knowledge tests because they include chain-of-custody documentation.

Not Covered by Health Insurance

DNA paternity and relationship testing is classified as a non-medical test and is not reimbursed by health insurance plans. Payment is collected directly at the time of testing.

Free Consultation

We walk you through pricing on the phone before you commit. There is no charge to call, no charge to ask questions, and no obligation to book a test after the consultation.

Discounts for Multiple Parties

Tests that involve additional parties (for example, a paternity test that also includes the mother, or sibling tests with multiple siblings) often qualify for a per-person discount. Confirm by phone before your appointment.

Frequently Asked Questions

Where can I get a DNA paternity test in Brownsville, Texas?

TestMark DNA has a certified collection site at 864 Central Blvd Ste 900, Brownsville, Texas 78520. We schedule chain-of-custody (legal) collections here for you, and results are typically returned in 3 to 5 business days.

Do I need a doctor's order or court order for DNA testing in Texas?

A doctor's order is generally not required. However, if you are a New York State resident, a prescription, court order, or ordering by other authorized persons is required by state law for all DNA identity or relationship tests.

Can DNA testing be done without the mother present?

Yes. A DNA paternity test can be performed without a sample from the child's biological mother. Including the mother's sample is preferred when possible as it improves accuracy.

How long do DNA test results take near Brownsville?

Results for a standard DNA paternity test are typically returned within 3 to 5 business days from when all samples are received at the laboratory.

Is DNA testing confidential?

Yes. All samples are packaged in tamper-proof bags and processed at an accredited laboratory with restricted access. Results are shared only with authorized individuals and are never released over the phone.

What type of sample is collected for a DNA test?

The standard sample is a buccal swab - a cotton swab rubbed gently inside the inner cheek. It is painless, non-invasive, and provides the same accuracy as a blood sample.

Will DNA test results be accepted in court?

Results from a legal DNA paternity test performed at an accredited facility may be accepted in court, provided the chain-of-custody form was completed according to laboratory guidelines. Non-legal test results are not intended for court use.

Is DNA paternity testing covered by health insurance?

DNA paternity testing is considered a non-medical test and is not covered by health insurance plans.

Is the Brownsville DNA collection site inside Valley Baptist Medical Center?

No. It is in Suite 900 of the Central Diagnostic Clinic building at 864 Central Boulevard, a separate medical office building next to the hospital.
