HelpTest Code BUPM Buprenorphine and Norbuprenorphine, Random, Urine
Useful For
Monitoring of compliance utilizing buprenorphine
Detection and confirmation of the illicit use of buprenorphine
Method Name
Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
Reporting Name

UrineOrdering Guidance
For screening buprenorphine alone, order BUPS / Buprenorphine Screen, Random, Urine.
For comprehensive opioid screening, order TOSU / Targeted Opioid Screen, Random, Urine.
For situations where chain of custody is required, a Chain of Custody Kit (T282) is available. For chain-of-custody testing, order BUPMX / Buprenorphine and Norbuprenorphine, Chain of Custody, Random, Urine.
Additional drug panels and specific requests are available. Call 800-533-1710 or 507-266-5700.
Additional Testing Requirements
If urine creatinine is required or adulteration of the sample is suspected, the following test should also be ordered, ADULT / Adulterants Survey, Random, Urine.

Specimen Stability Information
| Specimen Type | Temperature | Time | Special Container |
|---|---|---|---|
| Urine | Refrigerated (preferred) | 14 days | |
| Ambient | 14 days | ||
| Frozen | 14 days |
Reference Values
Negative
Cutoff concentrations:
Buprenorphine: 5.0 ng/mL
Norbuprenorphine: 2.5 ng/mL
Interpretation
The presence of buprenorphine above 5.0 ng/mL or norbuprenorphine above 2.5 ng/mL is a strong indicator that the patient has used buprenorphine.
