Court-ordered hair testing in Tarrant County
For a Tarrant County or Fort Worth court order, collect at 601 University Dr, Suite 103, Fort Worth, TX 76107, or schedule a mobile collection. Bring photo ID and the order. Hair is often used when the court wants a longer history than a urine test can show.
Court-ordered hair testing in Dallas County
Dallas collections are at 900 Jackson St, Suite 160. Same chain-of-custody process. Call (972) 898-1846.
Hair vs urine for a custody case
Urine shows recent use, usually days. Hair can show roughly 90 days and a pattern of use. Many family-law orders use hair as a baseline and urine or a sweat patch for follow-up. We collect all three.
Rapid hair vs lab hair
We offer two hair collections. Rapid hair screening can return a preliminary result in about 10 minutes at the Fort Worth or Dallas site. A rapid 10-panel is $155. Rapid THC-only hair is $65. Some court orders call for rapid hair. If the order says rapid hair, that is the test we collect. If the order says hair follicle or 90-day hair with a laboratory report, we collect the lab hair test. Bring the order so we collect the version the court named. Lab hair is the longer-history test. Rapid hair is the same-day screen.
