Cannabinoids, Urine
Test Name Cannabinoids, Urine (Delta-9-tetrahydro-cannabinol, Marijuana, THC)
Specimen Type / Requirements Container Type = Sterile Container Minimum Testing Volume = 0.5 mL Urine Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Collect sample in a sterile container. The preferred urine specimen especially for macroscopic analysis is a well-mixed first morning “mid-stream”. This is the most concentrated specimen and is most likely to reveal abnormalities. Random urine specimens may be used. Write your initials, date and time of collection on the collection label or requisition. Special Instructions Transfer aliquots in polypropylene tubes. Centrifuge urine sample before analysis. The sample should be within the normal physiological pH range of 5-8. Rejection Criteria: Unlabeled, Leaky or Not Sufficient Quantity Samples will be rejected. Stability: Stable at room temperature for 7 days, refrigerated for 28 days, and frozen for 28 days. Transportation: Send sample to core lab as soon as possible.

Turnaround Time (TAT) 48 hours	Test Utilization N/A
Reference Value < 20 ng/mL Results are obtained by a semi-quantitative immunoassay, which provides an estimated concentration of cannabinoid metabolites present in urine.
