TEST BASICS ## What is a hair follicle drug test and how does it work? A hair follicle drug test detects drug metabolites embedded in hair shafts, reflecting drug use over approximately 90 days. It uses a small hair sample, typically taken from the scalp, to analyze for substances like opioids, cocaine, amphetamines, and marijuana. Unlike [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests that detect recent use, hair follicle testing provides a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/), making it suitable for employment screening, legal cases, and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) monitoring. ORDERING ## How can I get a hair follicle drug test arranged through AMH Nationwide? To get a hair follicle drug test, you must contact AMH Nationwide to request a lab order. AMH does not offer online ordering; all tests are coordinated by phone or direct contact. Once the order is placed, AMH directs you to one of the five national lab networks for collection: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. Call (877) 731-6362 to initiate the test order. AMH provides a lab requisition and collection site location. Visit the assigned collection site for sample collection. WHO ORDERS ## Who typically requests hair follicle drug testing? Hair follicle drug tests are ordered by employers, legal authorities, probation officers, and sometimes individuals seeking long-term drug use verification. This test is preferred when a longer detection window is needed beyond what urine or saliva tests provide. It is not used for DOT-regulated safety-sensitive roles, which require federally certified urine testing. COLLECTION ## What happens during hair follicle drug test collection? A trained technician collects about 1.5 inches of hair closest to the scalp, typically from the crown of the head. If scalp hair is unavailable, body hair may be used but with limitations. The sample is sealed and sent to the lab for analysis. Collection is non-invasive and usually takes minutes. ## Ready to Schedule Your Hair Follicle Drug Test?

The hair sample is tested at one of AMH’s five national lab networks using validated laboratory methods. Any initial positive result undergoes confirmation testing. All non-negative results are reviewed by a certified Medical Review Officer (MRO) to ensure accuracy and to consider medical explanations before final reporting. RESULTS & LIMITATIONS ## What are the limitations and detection window of a hair follicle drug test? Hair follicle testing typically detects drug use within the past 90 days. It cannot detect very recent use within the last 5-7 days because it takes time for drugs to incorporate into hair. Passive exposure is unlikely to cause a positive result due to strict cutoff levels. The test cannot be ‘beaten’ by cleansing products; labs follow strict protocols to ensure sample integrity. PRICING & ACCESS ## How much does a hair follicle drug test cost and how do I get a quote? Pricing varies based on the drug panel and detection window requested. AMH does not publish prices online because costs depend on test specifics and collection site fees. To get a price quote or arrange testing, call (877) 731-6362. AMH staff will provide guidance and direct you to a convenient collection location.

A direct lab order is required, but no doctor’s prescription is necessary. Results typically take 3 to 5 business days after sample collection. The timeline includes lab analysis and Medical Review Officer evaluation. No. DOT-regulated drug testing requires federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair follicle tests are used for non-DOT safety-sensitive positions. Labs use validated methods to minimize bias due to hair color or type. The test analyzes drug metabolites in hair regardless of color or texture. Hair testing generally covers about 90 days. Hair grows approximately 0.5 inches per month, so testing longer periods requires longer hair samples which are not standard. Call (877) 731-6362 to discuss expedited collection options. Some collection sites may offer faster turnaround depending on location and lab processing.
