Reference Interval
Interpretive Data
Methodology: LC-MS/MS

Drugs covered
: Meperidine and normeperidine (meperidine metabolite)

Positive cutoff
:
Meperidine: 2 ng/mL
Normeperidine: 5 ng/mL

For medical purposes only; not valid for forensic use.

The presence of metabolite(s) without parent drug is common and 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, diluted/adulterated urine, 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.
