Reporting Name
Buprenorphine Screen w/Reflex, UPerforming Laboratory
Mayo Clinic Laboratories in Rochester
Useful For
Screening and confirmation for drug abuse or use of buprenorphine
Method Name
Immunoassay
Ordering 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 Testing Requirements

Reject Due To
All specimens will be evaluated at Mayo Clinic Laboratories for test suitability.Reference Values
Negative
Screening cutoff concentration:
Buprenorphine: 5 ng/mL
Interpretation
If the screen result is negative, buprenorphine concentrations were not detected.
If the screen result is positive, then confirmation by liquid chromatography tandem mass spectrometry will be performed.
A positive interpretation will be given if either the buprenorphine result is greater than or equal to 5.0 ng/mL or the norbuprenorphine result is greater than or equal to 2.5 ng/mL.
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.
