Emergency and after-hours testing is not comparable to standard clinic services. This is an on-demand, mobile response designed for time-sensitive and compliance-driven situations.
We travel directly to your location—job site, office, or facility—eliminating delays and ensuring timely collection when it matters most.
Services are available nights, weekends, and holidays when most clinics are closed and unavailable.
Timely testing helps protect your company from liability and ensures adherence to DOT and workplace policies.
Emergency requests are prioritized to reduce wait time and support urgent post-accident or reasonable suspicion situations.
This service is designed for businesses that need immediate, reliable action—not delayed or next-day scheduling.
Serving Houston, TX and surrounding areas including Sugar Land, Katy, Pearland, and The Woodlands.
Minimum Service: $250
Certain situations require immediate testing to protect your company, maintain compliance, and reduce liability. Delays can impact results and create risk.
Required after workplace incidents or accidents. Testing should be completed as soon as possible to remain compliant and protect your organization.
If an employee shows signs of impairment, immediate testing is recommended to document and address the situation appropriately.
