Test Code TXPRO 
Test TOXICOLOGY PROFILE, URINE 
Methodology Enzyme Immunoassay (EIA)
Cloned Enzyme Donor Immunoassay (CEDIA)
Gas Chromatography-Mass Spectrometry (GC-MS), if indicated
Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS), if indicated 
Description Screens for the following drugs/drug classes: amphetamines, barbiturates, benzodiazepines, cocaine metabolite, methadone, methadone metabolite, MDMA (Ecstasy), opiates, oxycodone, phencyclidine (PCP), propoxyphene, tetrahydrocannabinol (THC) and ethanol. Positive test results are confirmed and/or quantitated 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 80 mL (50.0 mL minimum) from a random urine collection in a non-sterile urine container. Send specimen refrigerated.
