Reference Interval

Effective February 16, 2016

Drugs Covered Cutoff Concentrations
Buprenorphine 1 ng/mL
Norbuprenorphine 1 ng/mL

Interpretive Data

Methodology: Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Positive cutoff: 1 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 noncompliance, 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.
