OVERVIEW ## What is an at-home hair drug test kit? An at-home hair drug test kit is a testing method that analyzes a small hair sample to detect drug metabolites over an extended period, typically up to 90 days. It is designed for non-DOT testing purposes and provides a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) compared to [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. The kit itself is a guide and set of instructions to collect a hair sample at a designated collection site, not an online or self-collection kit. USERS ## Who orders an at-home hair drug test kit? Employers, legal professionals, rehabilitation centers, and individuals may order an at-home hair drug test kit to verify drug use history. It is preferred when long-term detection is necessary, such as in employment screening, custody disputes, or personal monitoring. AMH Nationwide facilitates the lab order and directs the requester to a collection site but does not provide online ordering. DETECTION WINDOW ## What drugs can an at-home hair drug test kit detect and for how long? The at-home hair drug test kit detects commonly abused substances including marijuana, cocaine, opiates, amphetamines, methamphetamine, PCP, and others. It can identify drug use within approximately the past 90 days, reflecting a longer detection window than urine tests which typically detect recent use only. Detection window: Up to 90 days Common drugs tested: Marijuana, cocaine, opiates, amphetamines, PCP Suitable for non-DOT testing roles only COLLECTION ## How is the hair sample collected for this test? Hair collection is performed at one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. A small sample of hair is cut close to the scalp, usually from the crown area, to ensure recent growth is tested. The collection process is supervised by trained personnel to maintain chain of custody and sample integrity. Sample size: Approximately 1.5 inches of hair Collection sites nationwide via national lab networks Chain of custody maintained No self-collection or online ordering available ## Ready to Schedule Your At-Home Hair Drug Test?

This ensures accuracy and proper interpretation of findings. GETTING STARTED ## How do I start using an at-home hair drug test kit?
