What You Need to Know
Simply put, random drug testing in a workplace is an automated process that selects an employee for screening at any time, with an equal chance for every employee to be chosen. In addition, there are strict standards and procedures employers must adhere to when they select employees for screening. Employers should employ a statistically valid random selection system (typically a computer algorithm) that allows for each person to be equally chosen. The employer then needs to draw names for screening from their entire employee pool at regularly scheduled intervals, typically quarterly. Those employees then need to be tested within a set timeframe.
At Odosek Lab Solutions, we travel directly to your Columbia business location to perform the screening onsite in order to minimize time away from the job site. Whether your location is at a warehouse on Bluff Road, a healthcare center close to Forest Acres, or near a construction site near the airport, we will have a trained and experienced collector come onsite to your business location at your specified time to draw a specimen from the selected employees.
Each specimen must go through a rigorous chain of custody, from the time of draw until results are received back to the employer. To ensure all results are accurate and legally defensible, all drug testing specimens will be analyzed through an accredited laboratory by the Substance Abuse and Mental Health Administration (SAMHSA), and we perform every screening to meet Department of Transportation guidelines. Ninety percent of all screenings we perform will typically be standard urinalysis panels for any of the drugs listed above, as well as other commonly found drug classes, such as cocaine, marijuana, and methamphetamine. We can also perform oral fluid screenings as well as more extensive panels if desired. The entire process, including collection and chain of custody, typically takes approximately 15 minutes per employee.

No, you cannot choose which employees get tested. A valid random program uses a computer algorithm that gives every employee an equal chance of being selected. Names are drawn from your full employee pool at set intervals, usually quarterly or monthly. Odosek Lab Solutions helps Columbia employers set up a selection process that is fair, consistent, and legally defensible. This protects you from employee bias claims and keeps your program running cleanly.

We serve locations across the Midlands, including warehouses on Bluff Road, healthcare centers near Forest Acres, and construction sites near the airport. Our goal is to fit into your schedule with as little disruption as possible.
You need to keep records of your selection method, the dates testing was conducted, and the results for each employee. Employees should also be notified in writing that they may be selected at any time. Odosek Lab Solutions manages the chain of custody documentation for every specimen we collect. This means your Columbia business has a clear paper trail if your program is ever questioned. Good records protect you legally and keep your program running smoothly.
