The Experts in Full-Service Drug Testing

For over 30 years, Tomo Drug Testing has been trusted by organizations that cannot afford mistakes. Founded in 1991 to eliminate the inefficiencies of off-site testing, Tomo pioneered onsite drug and alcohol testing solutions that protect productivity, confidentiality and compliance. In 2015, the company expanded into forensic testing for court and community programs and rebranded as Tomo Drug Testing in 2016.

Serving more than 3,000 clients across eight states, Tomo delivers pre-employment, random, post-accident, reasonable suspicion and follow-up testing for employers, courts, schools and federally regulated organizations. Our onsite approach minimizes disruption, while proprietary data systems streamline compliance, reporting, audits and training.

Responding to a Critical Need

Tomo was founded to solve a real compliance problem: the operational and productivity costs of sending employees to off-site clinics for testing. That original mission—bringing reliable, compliant testing directly to the workplace—still defines the company today. Through growth, expansion and industry change, Tomo has remained focused on accuracy, accountability and protecting people, time and resources.

A Proactive Approach to Workplace Safety

Tomo helps organizations move beyond reactive testing toward proactive risk management. Through coordinated, multi-site programs and standardized policies, Tomo reduces administrative burden, lowers exposure and supports safer, more productive operations—especially for complex, multi-location organizations.

Streamlining Service with Data

As a Third-Party Administrator, Tomo manages testing data across all programs it serves. Proprietary systems support faster results, flexible testing methodologies, policy consultation and targeted training. These data-driven insights help clients identify patterns, address vulnerabilities and make informed, defensible decisions that strengthen long-term safety and compliance.
