TEST TYPES #
Urine Testing
Amphetamine (amphetamine and methamphetamine) is one of the "SAMHSA-5", the five drugs tested for in U.S. government-approved basic drug tests. Amphetamines are standardly detectable in urine for 1-3 days after use. Methamphetamines stay in the system slightly longer, 3-5 days.
The Amphetamine test is a one step competitive immunoassay that is used to screen for the presence of amphetamine in urine. It is a chromatographic absorbent device in which drug or drug metabolites in a sample compete with drug conjugate immobilized on a porous membrane for a limited number of binding sites. This test is a rapid, qualitative immunoassay for the detection of amphetamine in urine. The cutoff concentration for this test is 1000 ng/ml, as recommended by the Substance Abuse and Mental Health Services Administration. The cutoff for GC-MS, which detects d-amphetamine and methamphetamine, is 500 ng/ml.

Hair Testing
Amphetamine is detectable with hair tests and is included in the standard set of substances tested for with these tests. Hair tests generally take the most recent 1.5 inches of growth and use those for testing. That provides a detection period of approximately 90 days. If an individual's hair is shorter than 1.5 inches, this detection period will be shorter.
Saliva Testing
In the past few years, new technologies have been developed which allow for saliva testing for the presence of Methamphetamine and its derivatives. We do not currently have information about what the detection period is for these tests.

CAUTION & DISCLAIMER #
Erowid's drug testing information is a summary of data gathered from site visitors, journal articles, websites, and other resources. Detection periods depend on amount and frequency of use, metabolic rate, body mass, age, overall health, drug tolerance, and urine pH of each individual. Many substances that are not tested for in basic or extended urinalysis tests CAN be tested for by a laboratory willing to go to the trouble, although that is uncommon.
