Supporting Your Journey Back to the Driver’s Seat

At CoviLab Charlotte, we specialize in guiding commercial drivers through the DOT Return to Duty process with accuracy, speed, and compassion. Originally established as a private clinical lab focused on molecular diagnostics and COVID-19 RT-PCR testing, CoviLab has since expanded its services to include RTD testing for CDL holders.

We understand the stakes. That’s why we’ve built a streamlined, judgment-free environment where truckers and CDL drivers can navigate the SAP Return to Duty process with confidence. Whether you’re searching for a return-to-duty drug test near me or just starting the CDL return-to-duty process, we’re here to help at every step.

Our Expertise

CoviLab is a CLIA-certified laboratory staffed by experienced Lab Directors and Technicians with over 20 years of combined expertise.

We continue to contribute to diagnostic research, working to develop innovative tools for long-term health conditions, including cancer.
