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 Guide 34.  As a producer accredited by the ANSI-ASQ National Accreditation Board we offer your organization quality materials to be used as reference materials, blind and double-blind QC, performance testing (PT) samples and internal quality assurance samples. Refer to certificate and scope of accreditation AR-1984.

Our samples are often utilized by QA/QC departments for internal quality control to monitor the progress of an analyst, method or instrument.  Many clients use the samples in method validation or troubleshooting. 

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

Depending on your company’s need in QA/QC assessment we have a reliable product that will meet your need for quality assessment.
