Buprenorphine and Metabolites, Urine, Quantitative
Also known as: BUPR UR
Use
The test is used to obtain quantitative results or to follow up on a presumptive result. It is suitable for monitoring compliance with drug therapy and identifying potential abuse of buprenorphine. The presence of specific metabolites without the parent drug in the urine may indicate usage of the parent drug within the prior week.
Special Instructions
For general screening, the preferred test is Buprenorphine, Urine Screen with Reflex to Quantitation (2012273). Naloxone is included in the test to detect the addition of a naloxone-containing drug directly into the urine.
Limitations
The test is not valid for forensic use. The absence of expected drugs or metabolites may indicate non-compliance or issues with drug absorption. Environmental factors like diluted or adulterated specimens can affect test results. Concentration must meet or exceed the cutoff to be reported as positive.
