The amphetamine test assesses the presence of amphetamine in the urine. Amphetamine is a stimulant and a common street drug. It can also be used as a prescription medication for certain conditions but it is often detected in higher levels when the use is recreational. Amphetamine is removed from the body in the urine and this test can be used to assess recent amphetamine use.
You will need to provide a urine sample for this test. The test results are reported as positive (amphetamine present) or negative (no amphetamine present).
Am I required to fast for this test?
No, you do not need to fast for this test. However, if you are concurrently having another test done that requires fasting, you need to fast for that test as indicated.
What are negative results?
A negative test means that no amphetamine was detected in the urine and indicates that there has not been a recent amphetamine use. The cut-off value for detection of amphetamine in the urine is 1,000 ng/mL. If levels lower than these are present, they may not be detected and the test may be false negative.
What do positive results mean?
A positive test indicates amphetamine use within the last 1 to 4 days. Chronic amphetamine users may give positive amphetamine urine test for up to 7 days.
Why is the test done?
This test may be done as a part of insurance- or court-mandated drug testing or if you are suspected of driving under the influence of drugs. The test may also be done as a part of an employee illegal drug screen.
What type of doctor should I see if results are abnormal?
See your primary health care provider who may refer you to a specialist, such as a substance abuse counselor.
