OVERVIEW ## What is a 7-panel hair follicle drug test? A 7-panel hair follicle drug test is a method of drug screening that detects seven categories of drugs by analyzing a small sample of hair. This test provides a long [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) by identifying drug metabolites embedded in hair strands. It is often used for employment, legal, or forensic purposes, offering a more extended detection period than [urine](https://amhnationwide.com/urine-drug-testing/) tests. DRUGS TESTED ## Which drugs are included in the 7-panel hair follicle drug test? The 7-panel hair follicle drug test screens for the following drug classes: This panel covers commonly abused substances, ensuring a comprehensive overview of recent drug use. Amphetamines (including methamphetamine) Cocaine Marijuana (THC) Opiates (codeine, morphine, heroin) Phencyclidine (PCP) Benzodiazepines Barbiturates WHO ORDERS ## Who typically orders a 7-panel hair follicle drug test? Employers, legal entities, and rehabilitation programs commonly order the 7-panel hair follicle drug test to verify drug use history over several months. It is preferred in situations requiring a longer detection window than urine tests can provide. DOT-regulated employers do not use hair tests for safety-sensitive roles; hair testing is for non-DOT positions. DETECTION WINDOW ## What is the detection window for a 7-panel hair follicle drug test? The 7-panel hair follicle drug test typically detects drug use within the previous 90 days. Hair grows approximately 0.5 inches per month, and the standard 1.5-inch sample represents about three months of drug history. This extended detection period makes hair follicle testing valuable for assessing long-term drug use. ## Ready to Schedule Your 7-Panel Hair Follicle Drug Test?
