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 drug exposure.

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 within a drug class. Specimens for which drugs or drug classes are detected by the screen are reflexed to a second, more specific technology (GC/MS, GC/FID, 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.

Oxycodone results are reported with the opiates results. MDMA results are reported with the amphetamines results.

Note

If the specimen screens positive, then Confirmation/Quantitation by GC/MS, GC/FID, and/or LC-MS/MS will be added to confirm result. Additional charges apply.
