What is this test?
The Amphetamines Saliva Test is a confirmatory laboratory test that detects the presence of amphetamine-type stimulant drugs in your saliva (oral fluid). Amphetamines include medications like Adderall, Dexedrine, and methamphetamine (meth). This test uses advanced confirmatory methods, such as mass spectrometry, to accurately identify and verify the specific drugs present.
How is the sample collected?
A healthcare professional will collect a saliva sample by placing a absorbent collection device under your tongue or against your cheek for a few minutes. The sample is then placed in a sterile container and sent to a laboratory for analysis. This process is quick, non-invasive, and does not require blood draws.
Why is this test ordered?
This test may be ordered for several reasons: workplace drug testing programs, legal or forensic investigations, monitoring patients in substance abuse treatment programs, or to verify positive screening test results. The confirmatory method provides definitive results that can stand up in legal proceedings.
What do the results mean?
A positive result indicates that amphetamine-type drugs were detected in your saliva. A negative result means no drugs were detected at the time of testing. It is important to note that this test detects recent drug use, typically within 24-72 hours. Certain prescription medications may also cause positive results, so always inform the tester about any medications you are taking.
