Methamphetamine is excreted in the urine primarily as Amphetamine, and oxidized and delaminated derivatives. However, 10-20% of Methamphetamine is excreted unchanged.
Thus, the presence of the parent compound in the urine indicated Methamphetamine use. Methamphetamine is generally detectable in the urine for 3-5 days, depending on urine pH level.
One Step Methamphetamine Urine Test is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of Methamphetamine in urine/Saliva.
Test yields a positive result when Methamphetamine in urine reaches 1000ng/ml. This is the suggested screening cut-off for positive specimens set by the substance Abuse and Mental Health Services Administration (SAMHSA, USA ).
