Reference Materials

The Forensic materials production group within the Center for Forensic Sciences at RTI International specializes in producing custom-made, high-quality reference materials in accordance with ISO 17034. As a producer accredited by the ANSI-ASQ National Accreditation Board, we offer your organization quality materials to be used as reference materials for blind and double blind QA, proficiency testing, assay validation and analyst training. These samples also satisfy continued competency assessment as required by ISO 17025.

Over 80,000 samples are produced annually in matrices, including urine, blood/serum, oral fluid and hair. We specialize in drugs of abuse, metabolites, synthetic cannabinoids, therapeutic drug monitoring, and blood alcohol.

Manufactured according to your organization’s requirements, we deliver a reliable product that will meet your quality assessment needs.
