Specimen Collection Criteria

Collect: A random urine specimen in a screw-capped container (preferred) or other sterile collection container. Minimum is 10 mL for both pediatric and adult patients.

• See Minimum Pediatric Specimen Requirements.
• 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: Urine, refrigerated (2-8°C or 36-46°F). (Minimum: 10 mL for pediatric and adult patients.)

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.

STAT screen results available within 1 hour of receipt in the Laboratory.
Confirmation results available in 3-48 hours. 

Reference Range

See specific analytes for reference ranges.
This panel includes urine screening for: Amphetamine/Methamphetamines, Barbiturates, Benzodiazepines, Cannabinoid, Cocaine, Fentanyl, Methadone, Opiates, Oxycodone, Phencyclidine (PCP).

Test Methodology

Immunoassay, Gas Liquid Chromatography/Mass Spectrometery (GC/MS), Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS).

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

See specific analytes for interpretation.
This panel includes urine screening for:  Amphetamine/Methamphetamines, Barbiturates, Benzodiazepines, Cannabinoid, Cocaine, Fentanyl, Methadone, Opiates, Oxycodone, Phencyclidine (PCP).

Positive findings will be reported as "Unconfirmed positive." Confirmed results will follow within 3 to 48 hours. 

The laboratory will no longer automatically perform confirmation testing on positive THC screens in patients.  If a confirmation is needed, please call the lab to add the test on to the original specimen and the sample will be sent out to a reference laboratory for confirmatory testing.

Clinical Utility

See specific analytes for clinical utility.
This panel includes urine screening for:  Amphetamine/Methamphetamines, Barbiturates, Benzodiazepines, Cannabinoid, Cocaine, Fentanyl, Methadone, Opiates, Oxycodone, Phencyclidine (PCP).
