The amphetamine test assesses the presence of amphetamine in the blood. Amphetamine is a stimulant and a common street drug. It is also available as a prescription medication but it is often detected in higher levels when the use is recreational. The amphetamine blood test can be used to assess recent amphetamine use.
The amphetamine test is a simple blood test collected via venipuncture. The test results are reported as positive (amphetamine present) or negative (no amphetamine present). The results may also be given as milligrams per liter (mg/L).
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 you do not have amphetamine in your blood and indicates that there has not been a recent amphetamine use.
What do positive results mean?
A positive test indicates amphetamine use. Levels between 0.02 and 0.2 mg/L are generally considered normal therapeutic levels for prescription amphetamine use. Levels above 0.2 mg/L are a likely sign of amphetamine abuse and levels greater than 2.5 mg/L can be fatal.
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.
