Results
Rapid non-DOT screens give preliminary results in as little as 5 minutes. Lab specimens go to a SAMHSA-certified laboratory, with results typically in 24–72 hours. A non-negative result needs confirmation and MRO review, which can add 1–3 business days. Hair tests usually take 5–10 business days.
Workplace drug testing programs we run on site
Pre-employment drug testing
Screen new hires at your office before day one, without sending candidates across town.
Random employee drug screening
Collected on site for your random selections, so the whole crew isn’t pulled away.
Post-accident drug testing
24/7 dispatch after a crash or injury, to help you meet post-accident testing time windows.
Reasonable-suspicion testing
When a supervisor documents signs of impairment, a collector can come to your workplace.
DOT and non-DOT collections, done the right way
DOT-regulated employees (CDL drivers and other safety-sensitive roles) are collected under 49 CFR Part 40 and sent to a SAMHSA-certified laboratory with Medical Review Officer (MRO) review. DOT drug tests are laboratory tests, and rapid 5-minute screens are not used for DOT results. DOT drug testing →
Non-DOT employers can choose the panel and method that fit their policy: rapid urine or saliva screens on site, lab-based panels, hair testing, or breath alcohol testing. Non-DOT drug testing →
24/7 availability, same-day collection, rapid preliminary results
- Open 24 hours, 7 days a week, including nights, weekends and holidays, for second-shift crews and urgent tests.
- Same-day mobile collection throughout the Columbia area and the SC Midlands, subject to collector availability and scheduling.
- Rapid non-DOT screens: preliminary results in as little as 5 minutes. These are screening results. All laboratory confirmation drug testing offered by Odosek Lab Solutions uses urine specimens. If an initial oral-fluid screening requires confirmation, a separate urine collection will be arranged. A non-negative rapid screen needs laboratory confirmation and MRO review, which typically takes 1–3 business days beyond the standard 24–72 hour lab turnaround.
Five-minute results apply to rapid screening only. They never apply to DOT laboratory tests, hair tests or laboratory confirmation.
