I can’t say enough good things about Odosek! I contacted two other mobile DNA companies before calling them, and neither answered their phones. Odosek answered on the very first ring, and to my surprise, they were at my door just 45 minutes later!
From start to finish, the team was incredibly compassionate, professional, knowledgeable, and efficient. They truly went above and beyond to make the process as smooth as possible. I’m so grateful for their quick response and excellent service. I highly recommend Odosek to anyone needing DNA services!

Return-to-Duty Drug Testing in Columbia, SC
Most individuals are unaware that a return-to-duty test is not merely another drug screening. It is a distinct, legally mandated procedure governed by federal standards that offers no margin for error. Should you be an employee in a safety-sensitive role in Columbia seeking to resume employment following an infraction involving the use of illegal substances, all requirements must be fully met. There is no other option.
The specific test must be compliant with 49 Code of Federal Regulations (CFR), Title 40. This means the urine specimen must be observed under direct supervision, examined by a laboratory certified by the Department of Health and Human Services (HHS) Substance Abuse and Mental Health Services Administration (SAMHSA), and evaluated by a Medical Review Officer with appropriate qualifications. Should any portion of this process be disregarded, the test is rendered invalid. I have observed drivers in the vicinity of Fort Jackson and professionals located throughout the Midlands region lose their job opportunities for several months due to the necessity of repeating the test because it was conducted at an improper facility. The entire process must be repeated in its entirety.
However, the screening test is but the culminating segment of the process. Prior to the actual test collection, you must first undergo an evaluation performed by your Substance Abuse Professional (SAP), who must establish an appropriate rehabilitation or aftercare program and verify that you have successfully completed it. The return-to-duty test is only permissible to be conducted once the SAP has issued an affirmative statement confirming the same. This sequence is mandated. An employer that accepts a return-to-duty test prior to the SAP evaluation would be failing to maintain DOT compliance and would expose themselves to significant liability as a result. You can review the full federal framework in the Implementation Guidelines for Alcohol and Drug Regulations published by the FMCSA.

Frequently Asked Questions
What do I need to bring to my return-to-duty drug test in Columbia?
You need your SAP referral letter and a valid photo ID before we can collect your specimen. Your Substance Abuse Professional must sign off first — that is a federal DOT rule, not just ours. We verify your paperwork before anything else. At Odosek Lab Solutions, we come to you anywhere in Columbia or the Midlands, so you do not need to travel. Call us at 803-766-0036 and we will walk you through exactly what to have ready.
How long does the return-to-duty testing process take in Columbia?
The actual specimen collection takes about 15 to 20 minutes. Lab results from a SAMHSA-certified lab usually come back in one to three business days. After that, the Medical Review Officer reviews and reports results to your employer. We often collect on the same day you call us. Do not wait — your employer likely has a deadline. Call 803-766-0036 and we can get you scheduled fast.
Can my return-to-duty test be done at my home or job site in Columbia?
Yes — we come to you. Odosek Lab Solutions brings everything needed for a full DOT collection to your location in Columbia, whether that is your home near Rosewood, your employer’s site off Garners Ferry Road, or a nearby parking lot. We are available 24 hours a day, seven days a week. You do not wait in a line or travel anywhere. We handle the full chain-of-custody process right where you are.
What happens if my return-to-duty test is done at the wrong facility?
Your test result will be invalid and you will have to start the entire process over. We have seen this happen to drivers near Fort Jackson and workers across the Midlands. The test must be collected by a certified collector, sent to a SAMHSA-certified lab, and reviewed by a qualified Medical Review Officer. Odosek Lab Solutions follows full DOT Chain of Custody protocols on every single test so your results hold up.
Do I need to finish my SAP program before scheduling my return-to-duty test in Columbia?
Yes, your Substance Abuse Professional must confirm you completed their program before any return-to-duty test can happen. That clearance is required by federal DOT rules. Your employer cannot legally accept the test result without it. Most clients who contact us have already finished their program and just need the test done correctly. Not sure where you stand? Call 803-766-0036 and we will help you figure out your next step.
Is return-to-duty drug testing available on weekends and early mornings in Columbia?
Yes, Odosek Lab Solutions is available 24 hours a day, seven days a week — including weekends and early mornings. If a driver in the Rosewood area needs a 6 a.m. collection on a Monday, we will be there. Safety-sensitive jobs in Columbia do not run on a nine-to-five schedule, and neither do we. Call 803-766-0036 any time to schedule your return-to-duty test.
