Pre & Post Employment Drug Testing

ESR’s Flexible Options Put You in Control

We provide a fully integrated, electronic solution for substance abuse testing programs with access to more than 10,000 collection facilities and clinics in the United States.

Safer workplaces. Safer employees. A drug-free workplace can improve workplace safety and reduce injuries, reduce costs posed by the misuse of alcohol and drugs in the workplace, increase productivity and deter employees from engaging in the use of these substances at work.

ESR provides a fully integrated, electronic solution for your substance abuse testing program with access to more than 10,000 collection facilities and clinics in the United States. ESR also has the ability to facilitate international testing through U.S. or labs abroad.

Substance abuse testing is recommended for any organization to ensure a safe and healthy workforce and to comply with state and federal requirements. Certified Drug-Free Workplaces qualify for savings on insurance and workers’ compensation claim premiums and awards in many states.


ESR offers both regulated U.S. Department of Transportation (DOT) and non-regulated drug testing including Medical Review Officer (MRO) services.

ESR can accommodate an electronic chain of custody process for DOT and non-DOT testing which can be initiated through a secure online session in the ESRCheck® Solution.
