Test Information
This test was developed and its performance characteristics determined by Marshfield Labs.  It has not been cleared or approved by the US Food and Drug Administration.  This test is used for clinical purposes.  It should not be regarded as investigational or for research.

This test is a screen for Buprenorphone by immunoassay; if the screen is positive, this test automatically includes mass-spectrometry method quantitative confirmation for buprenorphine and its metabolite, norbuprenorphine. Quantitation/confirmation charged separately if needed.  It is intended for use only in patients where an initial drug screening test has not already been performed (i.e. Point-of-Care drug screening cup, dipstick, etc.). 
 
Buprenorphine is a member of the opioid family and is used as an alternative to methadone in the treatment of heroin addiction and as an analgesic for treatment of moderate to severe pain.  Buprenorphine is metabolized to norbuprenorphine.  Measurement of buprenorphine and norbuprenorphine assist the clinician in determining patient compliance with treatment.
Reference Range Information

Negative.  Positives are reported with a quantitative LC-MS-QToF or LC-MS/MS result.

Interpretation

Current Cutoff Levels for Toxicology

​Measurement of buprenorphine and norbuprenorphine assist the clinician in determining patient compliance with treatment.  Presence of the metabolite insures actual administration of the parent drug, however, quantitation of neither can be used to determine time or amount of dosage.  No therapeutic ranges are established for the compounds in urine.
