eScreen® is a trusted partner of the world’s largest retailer—among many other small and large businesses, of course. These clients—who employ millions of staff members—appreciate the far-reaching service eScreen provides due to our sophisticated technology and our huge, nationwide network of occupational health providers.

How many collection-site partners do we have? So many it’s hard for us to keep count!

That’s because eScreen’s Occupational Health Network (EOHN) is one of the largest networks of clinics in the country—and also includes collection sites in Canada. We include more than 5,100 service locations equipped with the eScreen Drugs of Abuse Screening System. These clinics can perform the lab-based specimen collections, breath alcohol tests, physical exams, and occupational health services you need to meet your efforts to maintain a drug-free workplace.

Our expansive collection-provider network ensures that you have the clinic coverage you need—no matter how many employees you test and no matter how far across the country they are spread.


  • Thousands of nationwide collection sites for expanded coverage in the U.S., Canada, and many international collection locations.
  • A paperless, electronic chain-of-custody form (our eCCF® paperless process) at technology-enabled locations.
  • 15-minute negative drug test results using eScreen’s patented screening technology.
  • The option to create a customized collection network to meet your specific program’s needs.
  • Onsite employee drug testing and occupational health services.
  • Clinics that offer a comprehensive choice of services, from drug screens and breath alcohol tests (BATs) to physical exams, occupational health services, blood tests, and more.
