Mon, Wed, Sat
Transfer 1 mL urine to an ARUP Standard Transport Tube. (Min: 0.6 mL)
Ambient: 1 month; Refrigerated: 1 month; Frozen: 1 month
Positive cutoff: 5.0 µg/mL
For medical purposes only; not valid for forensic use.
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 value must be greater than or equal to the cutoff to be reported as a quantitative result. Interpretive questions should be directed to the laboratory.
