What You Need to Know
The vast majority of employers located in Columbia are not subject to the federal Department of Transportation (DOT) drug testing regulations. Being excluded from the DOT, however, doesn’t allow you to abandon drug testing altogether, because it does mean that you can tailor drug testing to your needs. In our opinion, this flexibility is one of the greatest benefits of the process.
The types of drug testing that we offer for non-DOT employers are extensive, starting with pre-employment drug testing. When you’ve found the perfect candidate, you’ll know you need to run a drug test before you issue a verbal or written offer. We’ll meet you at your office or job site, or wherever else is most convenient for your organization, making the process a breeze for both your staff and your applicants. You won’t need to make candidates travel all over to a centralized facility.
We also conduct random drug testing at your office or job site. Are you operating a warehouse near Congaree Vista or a field crew in Northeast Columbia? We offer a random drug testing program that will make certain your staff are acting appropriately and staying focused while on the clock. Our technicians will stop by on-site and collect random samples in compliance with SAMHSA guidelines, and they will be processed in certified labs with a full chain of custody. No sample is left behind.

Common Questions
Non-DOT drug testing is workplace drug testing that follows SAMHSA-certified standards but is not required by federal DOT rules. Most Columbia employers fall outside DOT regulations, but that does not mean testing is optional. A positive result can protect you from liability, workers’ comp claims, and unsafe conditions. At Odosek Lab Solutions, we help businesses across Columbia and the Midlands build a testing program that fits their size and industry. Call us at 803-766-0036 to get started.
Columbia employers can choose from urine, hair, and oral fluid testing, plus 5-panel or 10-panel options depending on what substances matter most to your workplace. Pre-employment, random, reasonable suspicion, post-accident, and return-to-duty testing are all available. All samples go to SAMHSA-certified labs with a full chain of custody. Results are court-admissible, just like DOT tests. We help you pick the right panel for your industry, whether you run a construction crew in Northeast Columbia or a home health agency in the Midlands.
Our certified collectors come directly to you — no lab visit needed. We travel to your office on Harbison Boulevard, a job site near Fort Jackson, or even a private home in Irmo. Employees stay on-site, which saves time and removes the disruption of sending staff across Columbia for testing. This is especially helpful for businesses with hourly workers or tight schedules. Call Odosek Lab Solutions at 803-766-0036 and we will coordinate a time that works for your team.
We can have a certified collector at your Columbia location within the hour for reasonable suspicion situations. We are available 24 hours a day, seven days a week throughout Columbia and the Midlands. If a manager notices slurred speech, unusual behavior, or the smell of alcohol, do not wait. Call us at 803-766-0036 right away. Fast response protects your team, limits your liability, and creates a documented record if the situation escalates.
Yes, Non-DOT testing through Odosek Lab Solutions is fully valid for court-ordered situations, including custody battles, probation requirements, and family court cases in Columbia. These tests use SAMHSA-certified labs and include proper chain-of-custody documentation, which courts require. If your attorney has advised you to get tested, we can come to you quickly and handle the paperwork correctly. Results will hold up if challenged. Call us at 803-766-0036 to schedule at your convenience.
Have a valid photo ID ready for each person being tested. If you are an employer, know which panel type you need — 5-panel or 10-panel — and whether you want urine or hair collection. Our team will walk you through the rest when you call 803-766-0036. We confirm all details before we arrive so there are no surprises. A private restroom or quiet space at your Columbia location is helpful but we work with what you have.
