Learn how hair testing works and its use in trucking drug screening. Call (877) 731-6362 to schedule your test. --- Does C R England do hair follicle test? C R England primarily follows Department of Transportation (DOT) regulations, which require federally certified urine testing under 49 CFR Part 40 for safety-sensitive trucking roles. Hair follicle testing is generally not used for DOT-mandated drug screening but may be used for non-DOT positions. Call (877) 731-6362 to discuss testing options and scheduling. TESTING METHODS ## Does C R England use hair follicle testing for their drug screening? C R England does not typically use hair follicle testing for their DOT-regulated driver drug screenings. The trucking industry follows strict federal guidelines that mandate [urine](https://amhnationwide.com/urine-drug-testing/) drug testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40) for safety-sensitive positions. Hair follicle testing is more common for non-DOT roles or employer-specific policies outside federal regulations. C R England’s standard practice aligns with DOT urine testing protocols to ensure compliance and safety. DOT REGULATIONS ## Why does C R England rely on urine testing instead of hair follicle tests? The Department of Transportation requires urine testing for federally regulated commercial drivers. This testing uses a federally certified urine collection protocol to detect recent drug use within a typical [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) of a few days. Hair follicle testing, while capable of detecting drug use over a longer period (up to 90 days), is not accepted for DOT safety-sensitive employee screening. Therefore, C R England must follow urine testing to comply with federal law. HAIR TESTING DETAILS ## What are the specifics of hair follicle drug testing? Hair follicle drug tests detect drug metabolites deposited in the hair shaft, providing a detection window of approximately 90 days. This test can identify chronic or past drug use but does not detect very recent use within the last week. Hair testing is less prone to dilution or adulteration compared to urine but is generally reserved for non-DOT positions or certain employer policies. Results are reviewed by certified Medical Review Officers as standard practice. LAB NETWORKS ## Who processes hair follicle tests for companies like C R England?

TESTING ACCURACY ## How reliable is hair follicle testing compared to urine testing? Hair follicle testing is highly reliable for detecting drug use over the past 90 days, making it useful for identifying long-term use patterns. Urine testing is more effective for detecting recent drug use within days. Both test types undergo strict quality controls, and all non-negative results are reviewed by certified Medical Review Officers to confirm validity.
