Ordering Recommendation

Useful for general screening in contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out fentanyl exposure. For follow-up testing of a presumptive result, Fentanyl and Metabolite, Urine Quantitative (0092570) is preferred.

Interpretive Data

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 at which the screening test can detect a drug or metabolite varies. Specimens for which drugs or drug classes are detected by the screen are reflexed to a second, more specific technology (GC/MS and/or LC-MS/MS). 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.

For medical purposes only; not valid for forensic use.

Note

If the specimen screens positive, then Confirmation/Quantitation by LC-MS/MS (ARUP test code 0092570) will be added to confirm result. Additional charges apply.
