Description

The Methamphetamine Drug Test, (METH Drug Test), or The Cortez Diagnostics, Inc. DOA (Drug of Abuse) test, is an immunochromatography based one step in vitro test. The Methamphetamine rapid diagnostic tests are designed for qualitative determination of methamphetamine drug substances in human urine specimen. This assay may be used in the point of care setting.

Methamphetamine is the most popular synthetic derivative of the amphetamines. The methamphetamine drug is a potent sympathomimetic agent with therapeutic applications. Acute large doses of the methamphetamine drug lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power. More acute response to the methamphetamine drug produces anxiety, paranoia, psychotic behavior, and cardiac dysrhythmias. The Methamphetamine drug is excreted in the urine as amphetamine and oxized and deaminated derivatives. However, 10-40% of the methamphetamine drug is excreted unchanged. The Methamphetamine drug is generally detectable in the urine for 3 to 5 days after use.



Our Methamphetamine Drug Testing kits are 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 the methamphetamine 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 methamphetamine 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 Methamphetamine 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 Methamphetamine drug testing device is stored in good condition and the Methamphetamine drug test is performed appropriately.



This Methamphetamine Drug Test (METH Drug Test) 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.



The optional built-in Adulteration Test is for validation of urine specimens integrity and must not be used for In Vitro diagnostic use. The cutoff level for this Methamphetamine Drug Test (METH Drug Test) is 1000 ng/ml of (+) methamphetamine. For customized cutoff level methamphetamine drug tests, please contact Customer Service. This Methamphetamine Drug Test (METH Drug Test) is available in multi-panel, cassette, strip, or cup format.
