Employer drug testing for the Chicago metro area
Headquartered in Rolling Meadows, IL, with mobile and on-site testing coordination available across selected regions and employer locations. For the Chicago metro, feasibility for employer sites and job sites depends on site access, timing, test type, and scheduling needs—confirm with your quote or consultation request.
Chicago’s employer footprint spans O’Hare and Midway logistics corridors, I-90 / I-94 / I-55 spokes, and dense suburban industrial belts. Mobile and on-site collections reduce clinic trips for random batches, post-incident urgency, and hiring surges—when your sites can meet privacy and access requirements.
Illinois employers must align workplace testing with state law and written policy—not just federal DOT rules for regulated staff. We execute the collection and custody path your third-party administrator specifies; counsel remains responsible for how policy reads in Illinois.
Logistics landmarks we plan around
Dispatch and safety teams often cite O’Hare and Rosemont industrial pockets, the I-294 belt, Elk Grove and DuPage corridors, and downtown high-rises with strict freight and visitor rules. Lead times and routing depend on collector availability, time of day, and whether your site is gate-controlled.
Cross-dock and last-mile hubs near major interchanges may batch donors in one window; multi-floor offices need private staging and clear escort rules. Share addresses and urgency criteria in your quote request so feasibility is honest before you promise internal deadlines.
DOT and non-DOT in the same metro workforce
Many Chicago-area employers run blended programs: federally regulated transportation or safety-sensitive staff under DOT rules, and handbook-led testing for everyone else. Orders must state program type, test reason, and specimen so paperwork matches the path your DER and TPA expect.
