Buprenorphine and Norbuprenorphine, Random, Urine
Use
This test is useful for monitoring compliance in patients utilizing buprenorphine. It also aids in the detection and confirmation of the illicit use of buprenorphine, providing important information for those in therapy for opioid dependence. Buprenorphine is a partial mu-opioid receptor agonist, known for its utility in substitution therapy for opioid dependence and as an analgesic. The test detects both the parent compound and its metabolite, norbuprenorphine, in urine. The quantification of buprenorphine in urine helps in identifying patients deviating from opioid dependence therapy.
