Test Codes
FENT EPIC: LAB7958
Specimen Collection Criteria
Collect: 50 mL random urine in a screw-capped container (preferred) or other sterile collection cup with no preservative. (Minimum: 15 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 mL urine, refrigerated (2-8°C or 36-46°F). (Minimum: 30 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 specimen immediately upon receipt in the Laboratory.

NOTE: Confirmation performed at Royal Oak only.
The confirmation component of this test was developed by Beaumont Health. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes and should not be regarded as investigational or for research.
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
Fentanyl is a powerful synthetic opioid analgesic that is similar to morphine but is 80 to 100 times more potent. It is typically used to treat patients with severe pain or to manage pain after surgery. It is also sometimes used to treat patients with chronic pain who are physically tolerant to other opioids. The high potency of fentanyl greatly increases risk of overdose, especially if a person who uses drugs is unaware that a powder or pill contains it.
