Drug and Alcohol Testing in Houston, Texas

Maintaining a drug-free workplace is both a regulatory requirement and a practical necessity for Houston employers. From construction firms building downtown's next high-rise to corporate offices managing DOT-regulated fleets to hospitality companies staffing Midtown hotels, drug and alcohol testing is a foundational component of workforce safety. Hybrid Health Clinics at Crawford provides comprehensive testing services at 2101 Crawford Street — a central Houston location that minimizes the time your employees spend away from the job site or office.

Our Midtown clinic handles every category of employer-directed drug and alcohol testing with the speed, accuracy, and chain-of-custody compliance that protects both employers and employees:

• Pre-employment testing — standard urine panels, hair follicle testing, and oral fluid collections for new-hire screening. Results delivered electronically to streamline your onboarding timeline
• Random testing programs — we work with employers and third-party administrators (TPAs) to manage random selection pools, notification, and testing logistics on an ongoing basis
• Post-accident testing — immediate collection following workplace incidents. Our Crawford location accepts walk-ins during operating hours, and we coordinate after-hours testing for time-sensitive situations
• Reasonable suspicion testing — prompt collection when a supervisor determines testing is warranted, with proper documentation to support employer policy enforcement
• DOT testing — fully compliant 49 CFR Part 40 testing for drivers, pipeline operators, and other safety-sensitive positions regulated by FMCSA, PHMSA, FRA, FAA, and FTA
• Return-to-duty and follow-up testing — protocol-driven testing schedules for employees returning from Substance Abuse Professional (SAP) programs

Electronic chain-of-custody forms (eCCF) ensure that every collection is documented accurately and results are transmitted securely to the designated Medical Review Officer (MRO) and employer. For DOT-regulated employers, strict compliance with 49 CFR Part 40 procedures is not optional — it is the difference between a defensible program and one that exposes your company to liability. Our collectors are trained and certified to meet these standards without exception.

Houston's downtown employer base is uniquely diverse in its testing needs. A general contractor managing a commercial build on Main Street needs post-accident collections within hours. An energy company in a nearby tower needs quarterly random pulls for its pipeline division. A staffing agency onboarding warehouse workers for the Ship Channel needs high-volume pre-employment screens completed same-day. Our Crawford clinic handles all of these scenarios with the infrastructure and staffing to deliver results on the timeline that Houston's business environment demands.
