Useful for general screening in contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out cannabinoid exposure. For follow-up testing of a presumptive result, THC Metabolite, Urine, Quantitative (0090369) is preferred.
Qualitative Enzyme Immunoassay/Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Transfer 4 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min: 2 mL)
Ambient: 1week; Refrigerated: 1 month; Frozen: 3 years
Screen cutoff concentration: 20 ng/mL
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.
If the specimen screens positive, then Confirmation/Quantitation by LC-MS/MS (ARUP test code 0090369) will be added to confirm result. Additional charges apply.
80307; if reflexed, add 80349 (Reflexed Alt Code: G0480 )
