|Test||METHADONE AND METHADONE METABOLITE SCREEN WITH GC-MS CONFIRMATION, URINE|
|Methodology||Enzyme Immunoassay (EIA)
Gas Chromatography-Mass Spectrophotometry (GC-MS), if indicated
|Description||The screening assay detects methadone and methadone metabolite (EDDP). If the methadone screen is > = 300 ng/mL or the methadone metabolite screen is > = 1000 ng/mL, a methadone confirmation/quantitation by GC-MS is performed at an additional charge.
THIS TEST IS INTENDED FOR CLINICAL MONITORING AND MANAGEMENT OF PATIENTS. IT IS NOT INTENDED FOR NON-MEDICAL USE SUCH AS EMPLOYMENT OR FORENSIC TESTING.
Note: Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen
|Specimen||25 mL (10.0 mL minimum) from a random urine collection in a non-sterile urine container. Send specimen refrigerated.|
-Methadone EIA cutoff concentration: 300 ng/mL
|Analytic Time||1 Day; 4 Days if positive|
|Day(s) Test Set Up||Monday through Friday|
