Amphetamines are a class of potent sympathomimetic agents with therapeutic applications. They are chemically related to the human body's natural catecholamines: Epinephrine and nerepinephrine. Acute higher doses lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power. The effect of Amphetamines generally last 2-4 hours following use, and the drug has a half-life of 4-24 hours in the body. About 30% of Amphetamines are excreted in urine in unchanged form, with the remainder as hydroxylated and deaminated derivatives.
One Step Amphetamine 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 Amphetamine in urine. Test yields a positive result when Amphetamine 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).
