Antrim #17075, EPIC: LAB7013, SOFT: MET9
Specimen Collection Criteria
Collect: 50 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 mL urine, refrigerated (2-8°C or 36-46°F). (Minimum: 30 mL)
- 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.
Analyze urine specimen immediately upon receipt in the Laboratory.

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.
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.
Methadone is a synthetic narcotic analgesic that is similar to morphine. Methadone is commonly prescribed as the drug of choice in the maintenance treatment of heroin addicts. Patients in methadone therapy are routinely screened for methadone as a measure of compliance. This assay is used to aid in the diagnosis and treatment of methadone use or abuse. This assay provides a preliminary analytical result. Positive results are confirmed by chromatographic methods.
