From a single pre-employment screen to a full-scale workplace compliance program, Priority Diagnostics Inc has the certified mobile solution for your needs.
Federally mandated drug and alcohol testing for employers in the transportation sector. We perform fully compliant 49 CFR Part 40 collections for FMCSA, FTA, FAA, FRA, PHMSA, and USCG-regulated industries, including pre-employment, random, post-accident, reasonable suspicion, and return-to-duty testing.
Flexible, employer-driven drug testing for businesses not subject to federal transportation regulations. Includes pre-employment, random, post-accident, and reasonable suspicion testing, designed to support a safe, drug-free workplace and comply with California employer regulations.
Certified collectors available for all specimen types, urine, oral fluid (saliva), hair follicle, and breath alcohol. We partner with SAMHSA-certified laboratories and follow strict chain-of-custody protocols on every collection.
Screen new hires before they start work. Mobile pre-employment drug testing collected on-site at your facility, with results typically available within 24–48 hours. Available for both DOT and non-DOT employers.
We help employers establish and manage compliant random drug testing programs, including DOT consortium enrollment, selection notifications, and on-site mobile collection coordination. Protect your workplace and meet your DOT random testing rate requirements
Time-sensitive mobile response for qualifying workplace accidents. We dispatch immediately to your site, DOT and non-DOT post-accident collections with time-stamped chain-of-custody documentation. Post-accident testing windows are legally critical; call us the moment an incident occurs.
When a supervisor has documented observable signs of impairment, we respond quickly and professionally. Our certified collectors provide discreet, properly documented collections to support your reasonable suspicion determination.
Coordinated collections for employees returning to safety-sensitive duties following a positive drug or alcohol test. We work with your Substance Abuse Professional (SAP) schedule and follow-up testing requirements.
Confidential specimen collection for court-ordered drug testing, probation compliance, family court programs, and legal proceedings. We provide properly documented chain-of-custody collections accepted by courts and legal entities.
