THC

Federal and DOT-regulated workplace drug testing under SAMHSA guidelines includes marijuana as one of the five original mandated drug classes, with the inactive urinary metabolite THC-COOH (11-nor-9-carboxy-THC) serving as the target analyte for most marijuana immunoassay screening and confirmation testing. Laboratory testing applications include forensic toxicology investigations, driving under the influence of drugs (DUID) cases, pain management compliance monitoring to detect unauthorized cannabis use, and clinical toxicology assessments, with testing complexity increasing as state-level legalization creates varying regulatory requirements. UTAK’s DAU and Miscellaneous panels contain THC in lyophilized urine matrix at multiple concentration levels, supporting both immunoassay screening and confirmation methods used in clinical and forensic laboratories. Stock and custom QC solutions can incorporate related cannabinoids such as THC-COOH, cannabidiol (CBD), cannabinol (CBN), and other drugs of abuse analytes to address your laboratory’s comprehensive federal workplace, forensic toxicology, and drugs of abuse testing requirements.
