Use to detect drug exposure from among a targeted list of prescriptions, over-the-counter medications, and illicit drugs; for a complete list of drugs and drug metabolites detected, refer to Additional Technical Information. Not recommended to determine medication compliance or to assess for undisclosed drug/substance use in the context of pain management, substance use disorder treatment, or any other pharmacotherapies involving controlled substances. The drug screen panel can detect 127 drugs and drug metabolites by LC-MS/MS. 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. 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. This assay is for medical purposes only; not valid for forensic use. Note: If a specimen drug class is reported as positive, the test will report the confirmed component from the comprehensive drug class at no additional charge.
