Test Code:
090-30-1960-01

Order Name:
Amphetamine/ Methamphetamine (Urine), EIA *

 
Useful For:
Determination of amphetamine/ methamphetamine in human urine.
The assay Is intended for use in clinical laboratories. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used to obtain a confirmed analytical result.
Gas Chromatography/Mass Spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional Judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.

Clinical Information:
Amphetamines are synthetic derivatives of ephedrine. The most common amphetamines include d-amphetamine, d-methamphetamine, and d,/-amphetamine. They act as stimulants for the central nervous system.
Amphetamine is the most sympathomimetlc amine.
Amphetamines are readily absorbed from the gastrointestinal tract and are then either deactivated by the liver, or excreted unchanged in the urine. Normally. amphetamine is excreted as 30% unchanged in the 24 hour urine, depending on the urinary pH. The remainder is excreted as metabolites. 
Methamphetamine is normally excreted up to 43% unchanged in the 24 hour urine. The remainder is excreted as metabolites including amphetamine, its major active metabolite. Amphetamines appear in the urine within three hours after any type of administration, and can be detected for as long as 24 to 48 hours after the last dose.
