Specimen Collection Criteria
Collect: 50.0 mL random urine in a screw-capped container (preferred) or other sterile collection cup. (Minimum: 30 mL)
- Refrigerate the specimen immediately after collection.
- Record the exact time of specimen collection on the container or in the computer system.
Physician Office/Draw Specimen Preparation
Maintain specimen refrigerated (2-8°C or 36-46°F) prior to transport.
Preparation for Courier Transport
Transport: 50.0 mL urine, refrigerated (2-8°C or 36-46°F). (Minimum: 30.0 mL)
Rejection Criteria
- Specimens not collected and processed as indicated.
- Urine Vacutainer® tubes. Urine received in a glass or plastic tube with a rubber stopper may contain insufficient sample volume, preclude confirmatory testing, and give rise to contaminants and artifacts.
In-Lab Processing
Analyze urine specimen immediately upon receipt in the Laboratory.

Performed
Sunday – Saturday, 24 hours a day.
STAT screen results available within 1 hour of receipt in the Laboratory
Routine results available within 24 hours.
Reference Range
Negative (Positive Cutoff: 300 ng/mL).
Test Methodology
Enzyme Immunoassay.
Interpretation
Concentrations of drugs and/or metabolite(s) detected in urine have not been correlated to drug levels in the bloodstream or with the degree of impairment. The presence of a drug and/or metabolite(s) in urine is only an indication of previous drug exposure.
Clinical Utility
Opiates act on several sites of the central nervous system. Their use results in analgesia, drowsiness, mood changes and some mental clouding. This assay is used to aid in the diagnosis and treatment of opiate use or abuse.
