Reference Interval
Interpretive Data
Methodology: LC-MS/MS

Drugs covered: Buprenorphine, norbuprenorphine, buprenorphine glucuronide (qualitative only), norbuprenorphine glucuronide (qualitative only).

Positive cutoff:
Buprenorphine: 2 ng/mL
Norbuprenorphine: 2 ng/mL
Buprenorphine glucuronide: 5 ng/mL
Norbuprenorphine glucuronide: 5 ng/mL

For medical purposes only; not valid for forensic use.

The presence of metabolite(s) without parent drug may indicate use of parent drug during the prior week.

The absence of expected drug(s) and/or drug metabolite(s) may indicate non-compliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, or limitations of testing. The concentration value must be greater than or equal to the cutoff to be reported as positive. Interpretive questions should be directed to the laboratory.

Compliance Statement B: This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
