What it means
Workplace drug and alcohol testing spans pre-employment, random, reasonable-suspicion, post-accident and return-to-duty scenarios. DOT-regulated testing follows the strict 49 CFR Part 40 process — defined panels, chain of custody, certified labs and Medical Review Officer verification — while non-DOT testing follows employer policy. Managing collection sites, panels, results and the random pool is a core occupational-health workflow.
