Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms of methamphetamine use, such as rapid heartbeat, insomnia, or mood changes. It may also be used in workplace drug testing, legal investigations, or as part of a broader substance use evaluation.

What Does the Test Involve?

You’ll provide a urine sample in a sterile container. The sample is then analyzed in a lab to detect methamphetamine, which appears as a chemical compound in your body after use.

What to Expect Before the Test

No special preparation is needed, but avoid drinking excessive fluids before the test. If you’re on a strict diet or have kidney issues, let your provider know.

What Are Common Results?

Results are qualitative (positive/negative) rather than numeric, indicating whether methamphetamine was detected in your urine. A positive result suggests recent use.
