HHS Certified Oral Fluid Laboratories and Oral Fluid Collection Devices

This page contains a list of oral fluid drug testing laboratories certified by HHS under the National Laboratory Certification Program (NLCP). To comply with DOT’s drug testing regulation, 49 CFR Part 40, DOT-regulated employers may only utilize these laboratories and oral fluid devices.  The specific oral fluid collection device listed is approved for use by the laboratory by HHS and the NLCP. 

As a reminder, only when there are two HHS certified oral fluid laboratories may an employer begin to use oral fluid drug testing in the DOT drug testing program.
