Drug Testing Specimen Collection Sites

Drug and alcohol specimen collection can be a personal and bothersome task, but with VDT Testing, clients have access to over 10,000 DOT-approved testing facilities nationwide. Most testing stations are available to collect specimens for random selection testing, pre-employment screenings, reasonable suspicion testing, and post-accident testing, and each site’s collection specialists are trained to ensure specimen collections adhere to specific step-by-step collection protocols and Department of Transportation guidelines regarding security, privacy, facility standards, equipment, and analysis.
