Buprenorphine (Suboxone, Subutex, Sublocade) is widely used in treatment for opioid use disorder. LC-MS/MS testing detects both the parent drug and its primary metabolite norbuprenorphine, providing specific monitoring of compliance with prescribed therapy and distinguishing it from other opioids.
This test is used in addiction medicine to confirm patient adherence to prescribed buprenorphine therapy, evaluate possible misuse or diversion, and provide medico-legal documentation. Sample type is urine.
