Interpretive Data
Methodology: Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Positive cutoff: 10 ng/mL.
For medical purposes only; not valid for forensic use.
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, diluted/adulterated urine, or limitations of testing. The concentration value must be greater than or equal to the cutoff to be reported as positive. Norpropoxyphene is reported as qualitative only. Interpretive questions should be directed to the laboratory.
