Note: Some drugs are identified based on the presence of unique drug metabolite not listed above.
The absence of expected drug(s) and/or drug metabolite(s) may indicate noncompliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, diluted/adulterated urine, or limitations of testing. The concentration must be greater than or equal to the cutoff concentration to be reported as present. If specific drug concentrations are required, contact the laboratory within two weeks of specimen collection to request confirmation and quantification by a second analytical technique. Interpretive questions should be directed to the laboratory.   Results based on immunoassay detection that do not match clinical expectations should be interpreted with caution. Confirmatory testing by mass spectrometry for immunoassay-based results is available, if ordered within two weeks of specimen collection. Additional charges apply.   For medical purposes only; not valid for forensic use.
Use:Urine toxicology test to monitor medication compliances and detect undisclosed drug/substance use to support pain management, substance use disorders treatment, and other pharmacotherapies involving controlled substances. Testing is qualitative and uses a combination of mass spectrometry as well as immunoassays with documented low false positive rates. Secondary testing is generally not indicated but is available if confirmation or quantitation is desired.
