OVERVIEW ## Does CR England do hair follicle drug testing? CR England does hair follicle testing in certain circumstances, primarily for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) or random drug screening outside of DOT regulations. Hair follicle tests analyze a small sample of hair to detect drug metabolites, providing a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) than [urine](https://amhnationwide.com/urine-drug-testing/) testing. This method is often used when employers want to evaluate drug use over the past 90 days. Hair follicle testing detects drug use up to 90 days prior Non-DOT regulated roles may use hair testing Hair collection is non-invasive and tamper-resistant AMH Nationwide supports hair follicle testing routed through national labs including [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Call (877) 731-6362 for lab order assistance and collection site directions. TESTING PROTOCOL ## What is involved in CR England hair follicle drug test collection? Hair follicle drug test collection involves cutting a small sample of hair from the head or body, typically about 1.5 inches in length and 100 strands. The sample is sealed and sent to a [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-certified lab for analysis. Collection is supervised to prevent adulteration or substitution. Sample length covers approximately 90 days of drug history Collection is done at authorized sites directed by AMH Nationwide Samples are sent to certified labs for testing Every non-negative hair follicle test result is reviewed by a certified Medical Review Officer to ensure accuracy and interpret findings. CR ENGLAND POLICY ## Does CR England require hair follicle testing for DOT-regulated drivers? CR England follows DOT regulations for safety-sensitive roles, which require urine drug testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair follicle testing is not accepted for DOT-mandated drug screens. However, hair testing may be used for non-DOT roles or additional screening beyond DOT requirements. DOT roles require federally certified urine testing Hair follicle testing used for non-DOT positions or extended detection AMH Nationwide ensures compliance with DOT and non-DOT protocols For DOT drug testing needs, AMH Nationwide provides federally certified urine collections. Contact us at (877) 731-6362 for scheduling. DETECTION WINDOW ## How long can hair follicle testing detect drug use compared to other methods? Hair follicle testing can detect drug metabolites in hair for up to 90 days after use, making it one of the longest detection methods available. Urine testing typically detects recent use within 1 to 4 days depending on the substance. Saliva and blood tests have even shorter windows. Hair follicle: up to 90 days detection window Urine: 1 to 4 days detection window Blood and saliva: hours to days Due to this extended window, hair follicle testing is favored when employers want to assess long-term drug use patterns. ## Need Hair Follicle Drug Testing for CR England?

Hair follicle testing is highly reliable and difficult to tamper with due to chain-of-custody procedures and lab certifications. Passive exposure to drugs, such as secondhand smoke, is unlikely to cause a positive hair test because metabolites must be incorporated into the hair shaft internally. Certified labs follow strict protocols Medical Review Officers verify all non-negative results Passive exposure rarely causes false positives AMH Nationwide ensures all hair follicle tests are processed through SAMHSA-aligned labs with expert review for accuracy.
