Also known as: BUPRSP
Use
The test is used to monitor patient adherence to buprenorphine therapy. This includes the detection and quantitation of buprenorphine and its metabolite norbuprenorphine in serum or plasma. The presence of metabolites without the parent drug may indicate use of the parent drug over the prior week.
Special Instructions
For medical purposes only; not valid for forensic use. The cut-off concentration for positive results is 1 ng/mL. Potential interpretive questions should be directed to the laboratory.
