An amphetamine screen is a blood test that checks for the presence of amphetamines or related stimulant drugs. It is ordered when a healthcare provider needs to detect recent use, such as in emergency care, workplace testing, or monitoring prescribed stimulant therapy.
What it measures
- Amphetamine — The parent drug, often taken for ADHD or narcolepsy.
- Methamphetamine — A potent stimulant that is closely related to amphetamine.
- MDMA (Ecstasy) — A recreational drug that may cross-react on some screens.
- Other sympathomimetic amines — Compounds like pseudoephedrine that can cause false positives.
Who it is for
Emergency room doctors, primary care providers, and occupational health clinicians typically order this test. It may also be requested by pain management or addiction specialists.
Preparation
No fasting or special preparation is usually required. Tell your provider about any prescription or over-the-counter medicines you take, as some can affect the result.
Results and what they mean
Results are reported as positive (detected) or negative (not detected), sometimes with a numerical level. A positive screen does not always mean intentional use; a clinician must interpret the result in context. This is general information, not medical advice.
