|Test||BUPRENORPHINE SCREEN WITH LC-MS/MS CONFIRMATION, URINE (BASED ON POSITIVE SCREEN)|
|Methodology||Cloned Enzyme Donor Immunoassay (CEDIA)
Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS), if indicated
|Description||Screens for the presence of buprenorphine in urine by EIA at a cutoff concentration of 5 ng/mL. Positive results are confirmed and quantitated by LC-MS/-MS at an additional charge.
THIS TEST IS INTENDED FOR CLINICAL MONITORING AND MANAGEMENT OF PATIENTS. IT IS NOT INTENDED FOR NON-MEDICAL USE SUCH AS EMPLOYMENT OR FORENSIC TESTING.
Note: Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen.
|Specimen||25 mL (10.0 mL minimum) from a random urine collection in a non-sterile urine container. Send specimen refrigerated.|
|Reference Values||Not Detected
The presence of buprenorphine at 5 ng/mL or norbuprenorphine at 5 ng/mL is a strong indicator that the patient has used buprenorphine.
|Analytic Time||1 Day; 4 Days if positive|
|Day(s) Test Set Up||Monday through Friday|
