Non-DOT Testing Only: Not a Certified DOT Site
Ironstone Medical Clinic provides non-DOT drug and alcohol testing for employers in Riverside. We are not a certified DOT (U.S. Department of Transportation) testing site, so we do not perform DOT-regulated tests for safety-sensitive transportation workers. If your employer requires a DOT test, please ask them for a DOT-certified collection site.
For non-DOT testing, we are an approved collection site with the trained staff, materials and equipment to collect urine specimens, store them securely and ship them to a laboratory. Employers can call (951) 778-0032 to set up non-DOT testing for their company.
