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.

Frequently Asked Questions
Where can I get a DNA paternity test in San Antonio, Texas?

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 San Antonio?
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.
