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 amphetamine exposure. For follow-up testing of a presumptive result, Amphetamines, Urine, Quantitative (2010075) 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.

Note

If the specimen screens positive, then Confirmation/Quantitation by LC-MS/MS (ARUP test code 2010075) will be added to confirm result. Additional charges apply.
