OVERVIEW ## What are trucking companies that do hair follicle test looking for? Trucking companies that do hair follicle test aim to identify drug use over an extended period, typically up to 90 days. Hair follicle testing detects parent drugs and metabolites deposited in the hair shaft from blood circulation. This test is especially useful for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) screening or random testing in non-DOT regulated roles. TESTING PROCESS ## How is hair follicle drug testing performed for trucking companies? Hair follicle testing involves collecting a small sample of hair, usually about 1.5 inches long, from the scalp. The sample is sent to one of AMH Nationwide’s five national lab partners—[Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox—for analysis. Results are reviewed by a certified Medical Review Officer to ensure accuracy and compliance. Sample length covers approximately 90 days of drug use history Non-invasive collection from the scalp or body hair if scalp hair is unavailable No online ordering; lab orders are managed by AMH Nationwide Results include confirmation tests for any positive initial screens REGULATORY CONTEXT ## Do DOT-regulated trucking companies use hair follicle testing? DOT-regulated trucking companies do not use hair follicle testing for safety-sensitive positions because federal regulations require [urine](https://amhnationwide.com/urine-drug-testing/) testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair follicle testing is typically used by non-DOT employers or for roles not subject to DOT drug testing rules. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What is the detection window for hair follicle drug testing in trucking? Hair follicle testing detects drug use from about 7 days after use up to 90 days prior. This contrasts with urine testing, which generally detects drug use within 1 to 7 days. The extended detection window helps trucking companies identify longer-term drug use patterns. ## Schedule Hair Follicle Drug Testing for Trucking Companies Contact AMH Nationwide to arrange hair follicle testing through our national lab network.

No, DOT regulations require urine testing under 49 CFR Part 40 for safety-sensitive positions. Hair tests are used for non-DOT roles or employers outside federal jurisdiction. Hair follicle tests typically detect substances such as marijuana, cocaine, opiates, amphetamines, and PCP, covering a wide range of commonly abused drugs. Results usually take 3 to 5 business days after collection, depending on the lab and panel complexity, with Medical Review Officer verification included. Certain hair treatments like bleaching or dyeing may reduce drug metabolite concentrations but do not guarantee test evasion and labs consider such factors during analysis. Trucking companies must call (877) 731-6362 to request lab orders and coordinate collections at nationwide sites. AMH does not provide online ordering.
