Ordering RecommendationRecommendations when to order or not order the test. May include related or preferred tests.
Useful for general screening in contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out meperidine exposure. For follow-up testing of a presumptive result, Meperidine and Metabolite, Urine, Quantitative (3000248) is preferred.

Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
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.
