Amphetamines are one of those many central nervous system (CNS) stimulants. Regular use of these substances results in increased energy, reduced hunger, wakefulness, increased blood pressure, and an overall feeling of well being. It is used to treat narcolepsy (a sleep disorder characterized by sudden and uncontrollable episodes of deep sleep) and some forms of depression. However, these stimulants are often abused by many of those workoholics. Amphetamine can be testes in various samples, and hence there are several variants of Amphetamine tests. The most popular one is the urine test, while others like hair and saliva based amphetamine tests are also gaining popularity. In a urine sample, the traces of amphetamines can be detected up to 3 days after the use. This is a one step rapid qualitative and competitive immunoassay test which is used to screen the presence of amphetamines. In contrast, the hair based amphetamine tests can observe the drug traces in the most recent 1.5 inches growth of the hairs, and thus the detection window of approximately 90 days is available. Saliva based testing is also available for the methamphetamines and its derivatives. In saliva amphetamine tests, a chromatographic absorbent device is used in which drug or its metabolites compete with a labeled antibody or drug conjugate immobilized on a porous membrane for a limited number of binding sites and this makes it a competitive method of screening. The test is marked positive as the amphetamine concentration reaches of 1000 ng/ml.
