​

Drug & Alcohol Testing

What’s the difference between DOT and non-DOT drug testing?

• DOT testing is federally regulated and required for safety-sensitive jobs in industries such as transportation, aviation, and trucking. These tests follow strict Department of Transportation rules. Non-DOT testing is more flexible and used by employers or individuals outside of federal regulation. Both are accurate and confidential, but DOT tests have stricter procedures and reporting.

How quickly will I get my results?

• Most drug test results are available within 24–48 hours, depending on the test type. Rapid test options may give results in just a few minutes. We’ll provide updates throughout the process so you’re never left waiting.

Do you offer on-site or mobile testing?

• Yes. We can come to your workplace, event, or location to perform testing. On-site testing helps minimize downtime, ensures compliance, and makes the process convenient for employers and employees alike.

Who needs random drug testing?

• Random testing is required for DOT-regulated companies. For non-DOT workplaces, it’s a best practice that promotes safety, reduces risk, and helps deter substance abuse.

What happens if an employee refuses to take a test?

• In DOT-regulated settings, refusal is treated the same as a positive test and must be reported. In non-DOT workplaces, outcomes depend on the company’s drug-free workplace policy. We can guide you on creating or updating your company policy.

Training & Safety Services

What’s included in OSHA 10 and OSHA 30 training?

• OSHA 10 covers entry-level workplace safety for general industry and construction.

• OSHA 30 goes deeper into health and safety standards, designed for supervisors, managers, and leaders.

• Both are taught by OSHA-authorized trainers and include an official completion card.

Do you provide certification for CPR, First Aid, and AED training?

• Yes. After completing the course, participants receive official certification that meets workplace and OSHA requirements. Your team will be prepared to respond in emergencies with confidence.
