Use

Screening for drug abuse or use of buprenorphine. This assay provides a preliminary analytical test result and must be confirmed by a more specific method such as liquid chromatography tandem mass spectrometry when a positive screening result occurs. It is useful in clinical monitoring and management but not intended for employment‐related or forensic testing. Buprenorphine is a partial mu-opioid receptor agonist with reduced clinical effects and prolonged duration; it is metabolized via N-dealkylation to norbuprenorphine, which is active but less potent, and then glucuronidated to inactive forms.
