4-Panel Drug Test (Strip) (Any Drug Combination) description:

Los Angeles based Diagnostic Automation/Cortez Diagnostics, Inc., maker of rapid diagnostic tests, offers a 4 Panel Drug Test for any combination drugs: Amphetamine (AMP), Barbiturates (BAR), Benzodiazepine (BZD), Buprenorphine (BUP), Cocaine (COC), EDDP, Fentanyl (FTYL), Ketamine, Marijuana/Cannabinoid (THC), MDMA (Ecstasy), Methadone (MTD), Methamphetamine (MET), Methylphenidate (MPD), Morphine, (MOR), Opiate (OPI), Oxycodone (OXY), Phencyclidine (PCP), Propoxyphene (PPX), Tramadol, and Tricyclic antidepressant (TCA).  This 4 panel drug testing kits are designed for qualitative determination of drug substances in human urine specimen.

The Four Panel Drug Testing device is based on the principle of specific immunochemical reaction between antibodies and antigens to analyze particular compounds in human urine specimen. The assay relies on the competition for binding antibody between drug conjugate and free drug which may be present in the urine specimen being tested.  When a drug is present in the urine specimen, it competes with drug conjugate for the limited amount of antibody-dye conjugate. When the amount of the drug is equal or more than the cut-off, it will prevent the binding of drug conjugate to the antibody. Therefore, a positive urine specimen on the 4 Panel Drug Test will not show a colored band on the test line zone, indicating a positive result, while the presence of a colored band indicates a negative result.  A control line is present in the test window to work as procedural control. This colored band should always appear on the control line zone if the 4 Panel Drug testing device is stored in good condition and the 4 Panel Drug Test is performed appropriately.

The four panel drug test kit-provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result.  Gas chromatography/ mass spectrometry (GC/MS) has been established as the preferred confirmatory method by the Substance Abuse Mental Health Services Administration (SAMHSA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated.
