What is this test?

The Amphetamine Urine Test is a laboratory test that detects the presence of amphetamine and methamphetamine in your urine. These are stimulant drugs that affect the central nervous system. The test uses immunoassay screening followed by confirmation testing if needed.

Urine testing is the most common method for detecting these drugs because traces of the substances remain detectable in urine for longer periods compared to blood or saliva. The test can identify use within the past 2-4 days for amphetamine and 2-5 days for methamphetamine.

Frequently asked questions

How is the sample collected?
You will be provided with a sterile container to collect a urine sample. The sample is usually collected under supervision to prevent tampering. You should provide a mid-stream urine sample by first urinating a small amount into the toilet, then collecting the rest in the container.
Do I need to prepare for the test?
No special preparation is needed. You can eat and drink normally before the test. However, inform your healthcare provider about all medications, supplements, and over-the-counter drugs you are taking, as some may affect the results.
How long do results take?
Screening results are usually available within 24-48 hours. If the initial screen is positive, confirmatory testing may take an additional 2-5 days.
Can a positive result occur from legal medications?
Yes, certain prescription medications containing amphetamine or pseudoephedrine (such as Adderall, Vyvanse, or cold medicines) can cause a positive result. Also, some dietary supplements and poppy seeds may affect results. Always disclose all medications to your healthcare provider.
Is the test confidential?
Yes, test results are protected by privacy laws and are only shared with authorized individuals. For workplace testing, results are typically sent to the employer or medical review officer designated by your organization.
