In Webster, Texas, TestMark DNA collects samples at 250 Blossom Street, Suite 180, in the Clear Lake Medical Office Building on UTMB Health's Clear Lake campus. It is a separate suite from UTMB's own lab in Suite 130, within about three-quarters of a mile of I-45 Exits 25 and 26.

The Clear Lake Medical Office Building at 250 Blossom Street, on UTMB Health's Clear Lake campus, holds TestMark DNA's Webster collection site in Suite 180. UTMB's hospital is its neighbour at 200 Blossom Street, and the office building's upper floors hold UTMB specialty clinics ranging from cardiology and neurology to pediatrics and maternal-fetal medicine. UTMB also runs its own clinical laboratory in Suite 130 of the same building, so Suite 180 is the door to look for when coming in for a DNA collection. The building sits where Blossom Street meets Sylvan Street, with Medical Center Boulevard and North Texas Avenue each about an eighth of a mile away. For DNA testing in Webster, Texas, the building number and Suite 180 together point to the right office.

Two Interstate 45 exits sit within about three-quarters of a mile of the building: Exit 25 for NASA Parkway (FM 528) and Exit 26 for Bay Area Boulevard and the University of Houston-Clear Lake. That university, which describes its campus as a wildlife and nature preserve in the heart of Clear Lake's high tech community, is about three miles away. Harris County family cases are heard downtown in the Civil Courthouse at 201 Caroline, and the Attorney General's Houston Southeast child support office on the Gulf Freeway is the nearest listed one, about eleven miles away.

In Webster, TestMark DNA is in Suite 180 of the Clear Lake Medical Office Building, at 250 Blossom Street.

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 Webster, Texas collection site is straightforward, painless, and typically takes less than 30 minutes. Here is what to know before you visit 250 Blossom St Ste 180.

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 250 Blossom St Ste 180 in Webster 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

Collection sites in Webster, Texas handle chain-of-custody (legal) tests ordered through TestMark DNA. We recommend scheduling your visit so everyone arrives prepared: call (866) 702-7644 and we'll confirm the right test, book your collection, and tell you what ID to bring.

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 Webster, 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 Webster, Texas?

TestMark DNA has a certified collection site at 250 Blossom St Ste 180, Webster, Texas 77598. 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 Webster?

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 DNA collection site the same as the UTMB lab at 250 Blossom Street?

No. UTMB's own clinical laboratory is in Suite 130. TestMark DNA's collection site is Suite 180 in the same Clear Lake Medical Office Building at 250 Blossom Street, Webster.
