AMH Nationwide will provide a lab order for hair follicle drug testing collection throughout Texas using the [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox patient service center networks, which include locations in the state’s major metro areas such as Houston, Dallas-Fort Worth, San Antonio, and Austin, as well as many mid-sized cities across the state. **Gulf Coast:** Houston and the surrounding petrochemical corridor. **North Texas:** Dallas-Fort Worth and the I-35 corridor south to Austin and San Antonio. **Central Texas:** Austin and San Antonio metro areas. **West Texas:** the Permian Basin and communities along I-10 and I-20. Texas’s size and the geographic spread of its population means collection availability can vary by area; call (877) 731-6362 and AMH Nationwide can confirm the nearest participating site to a specific address before you schedule. Why Texas Employers Test ## Why Do Texas Employers Use Hair Follicle Testing? Texas has a significant energy and logistics economy, with heavy trucking and warehousing traffic along interstate corridors like I-35 between San Antonio and Dallas, I-45 between Houston and Dallas, and I-10 across the southern part of the state, along with oil and gas operations concentrated in areas such as the Permian Basin. Non-DOT employers in these industries sometimes choose hair testing for a longer look at candidate history. It is important to note that DOT-regulated safety-sensitive positions, including many commercial driving roles common in Texas logistics, currently require the federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing protocol under [49 CFR Part 40](https://www.transportation.gov/odapc/part40); hair testing is used for non-DOT roles and other employer, court, or personal purposes. ## Need hair follicle testing scheduled in Texas?

[Call (877) 731-6362](tel:+18777316362)[Contact Us](https://amhnationwide.com/contact-us/) Custody in Texas ## What Should Texas Families Know About Custody-Related Testing? Texas family courts, like courts nationwide, may request drug testing in custody or family law matters, and requirements for test type and [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) vary by court and by case. AMH Nationwide provides the laboratory testing and collection logistics but does not advise on what a specific Texas court will require; that is a question for your attorney. When a test is tied to a Texas custody matter try to have any documentation from your attorney or the court specifying the test type and who is authorized to receive results along when you call to schedule, since chain-of-custody protocols will apply. Scheduling ## How Do I Schedule Testing in Texas? Call AMH Nationwide or contact us to request hair follicle testing anywhere in Texas; the team will confirm the nearest location in our national lab networks based on the city or zip code you provide and walk you through scheduling. 1 ### Call or contact us Call (877) 731-6362 or contact us and share your city or zip code in Texas. 2 ### Confirm your site Receive confirmation of the nearest participating collection site in our national lab networks and receive the lab order you need for testing. 3 ### Visit for collection Visit the location with photo identification for collection. 4 ### Receive results Receive results after laboratory analysis and Medical Review Officer review. Multi-Location Employers ## What Should Multi-Location Texas Employers Know? Texas employers with operations across multiple cities, such as a logistics company with facilities in Houston, Dallas-Fort Worth, and San Antonio, can coordinate hair follicle testing for employees at any of these locations through a single point of contact rather than arranging separate vendors per city. This can simplify scheduling and results tracking for Texas employers managing [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) or workplace policy testing across a large, geographically spread workforce, from the Gulf Coast to the Panhandle and West Texas. Texas Geography ## What Makes Texas’s Geography Relevant to Testing Access? Texas is the second largest state by land area, and its population is spread across distinct regions, including the Gulf Coast around Houston, North Texas around Dallas-Fort Worth, Central Texas around Austin and San Antonio, and West Texas around the Permian Basin, each with its own concentration of lab collection sites. Texas at a Glance ### Statewide Access Snapshot 4Major Metro Regions ~90 DaysStandard Detection Window 6-12 MoExtended Panel Options 20,000+Collection Sites, 5 Lab Networks AMH Nationwide accounts for this spread when scheduling, confirming the closest available collection site to a specific address rather than assuming statewide uniform access, since travel time to a collection site can vary meaningfully across a state as large as Texas. Industries ## What Do Texas Energy and Healthcare Employers Typically Request? Texas’s energy sector, concentrated in areas such as the Permian Basin and the Gulf Coast petrochemical corridor, along with its large healthcare employers in metro areas like Houston and Dallas-Fort Worth, commonly request pre-employment and workplace policy testing, with hair follicle testing used by non-DOT employers wanting a longer look at candidate history. DOT-regulated positions within these industries, such as commercial drivers and certain safety-sensitive roles, still fall under the federally certified urine testing protocol rather than hair, regardless of the employer’s industry or location within Texas.
