What is this test?

The Amphetamine Hair Test is a laboratory analysis that detects the presence of amphetamines in a hair sample. Amphetamines are stimulant drugs that include prescription medications (like Adderall) as well as illicit substances (like methamphetamine). This test uses a confirmatory method called mass spectrometry to accurately identify and measure amphetamine levels in hair.

How does hair testing work?

When a person uses amphetamines, traces of the drug enter the bloodstream and become incorporated into growing hair follicles. As hair grows (approximately 1 cm per month), it retains these substances, creating a permanent record of drug use. A small sample of hair—typically from the scalp—is collected and sent to a laboratory for analysis. The confirmatory method uses specialized equipment to separate and identify drug compounds with high accuracy.

Why might this test be ordered?

Healthcare providers, employers, or legal authorities may order this test for various reasons: monitoring substance abuse treatment, workplace drug screening, forensic investigations, or assessing compliance with probation requirements. Hair testing is particularly valuable because it provides a longer detection window (weeks to months) compared to urine or blood tests.

What do the results mean?

A positive result indicates that amphetamines were detected in the hair sample, suggesting past drug use. The test can often distinguish between different types of amphetamines. However, this test cannot determine exactly when drugs were used, how much was taken, or whether someone was impaired at the time of collection. False positives can occur from environmental exposure or certain hair treatments, so confirmatory testing is important.
