Since 1986, RTI has supported the Department of Health and Human Services (HHS) by leading the National Laboratory Certification Program (NLCP). The NLCP is U.S. Government’s accreditation program for forensic laboratories performing federally regulated workplace drug testing.

RTI operates all aspects of the NLCP, including the inspection program for forensic drug testing laboratories; investigation of issues; and the manufacture, distribution, scoring, and reporting of performance testing (PT) samples.

Our team verifies laboratory procedures, data, and documentation, drawing on our extensive experience in forensic toxicology, which includes management and bench-level experience in HHS–certified drug testing laboratories. We also assembled and manage more than 100 expert consultants from academia, the military, and forensic toxicology laboratories to serve as NLCP inspectors.

The HHS-certified laboratories accredited under the NLCP are known as the “gold standard” in the drug testing industry. In fact, many states require drug testing to be performed by HHS-certified laboratories and many private-sector employers also choose these laboratories to test job applicants and employees.

We have been the government’s sole contractor for the NLCP since its inception because our work ensures accurate testing and maintains the reliability of the entire drug testing process, thus helping reduce the impact of substance abuse on America’s communities.
