How Our Mobile DOT Testing Works

Once you decide to bring testing on site, you need a clear picture of what to expect. Our process is designed to be straightforward, from the first phone call to final results. We work with you to plan around your routes, shifts, and job schedules so testing fits into your workday instead of interrupting it.

Here is what to expect during a typical mobile DOT visit:

• Our team arrives at your Houston-area location at the scheduled time and checks in with your point of contact.
• We set up a clean, private space for collections and review the testing roster together.
• Employees are called in one at a time for identity verification and specimen collection.
• Collectors follow DOT chain of custody procedures, complete paperwork, and secure all specimens.
• We pack and ship specimens to the appropriate laboratory or follow your program’s established process.

After collections are complete, results are reported according to your program’s structure and DOT guidelines. Many negative screening results are available quickly, while non-negative or confirmed results typically follow standard laboratory and review timelines. Throughout the process, we work to keep you informed and to handle records in a way that supports future audits or internal reviews.

DOT Testing Services We Provide On-Site

Different situations call for different types of testing, and DOT rules recognize that. Our mobile services are designed to support a wide range of DOT testing needs so you can work with one provider for your safety-sensitive workforce. We routinely serve transportation companies, contractors, and public agencies that operate in and around Houston.

DOT-Compliant Drug and Alcohol Testing

We can conduct random drug and alcohol tests on-site in coordination with your random selection program. For reasonable suspicion or for-cause situations, we work with you to schedule collections as promptly as possible so you can document your response and support safety decisions. When an accident or incident occurs, you may need support arranging post-accident testing; we can help plan and complete those collections in line with required timing whenever scheduling and access permits.

We also perform return-to-duty and follow-up tests that are part of many compliance plans. Depending on the type of test selected, our drug testing services can detect recent or longer-term use of substances commonly monitored in DOT programs. Our breath alcohol testing equipment is suited to DOT protocols, and all mobile testing follows the same strict standards that apply in our facilities.
