Roehl uses various drug tests but hair follicle testing is not standard. Learn more or schedule testing. Call (877) 731-6362. --- Does Roehl do hair follicle test? Roehl primarily utilizes urine drug testing and does not typically perform hair follicle drug tests. Hair follicle testing detects drug use over a longer period but is less common in Roehl’s standard screening. For comprehensive hair follicle testing, contact AMH Nationwide. Call (877) 731-6362. TESTING METHODS ## Does Roehl do hair follicle test? Roehl generally does not conduct hair follicle drug tests as part of its standard drug screening program. Their testing primarily relies on [urine](https://amhnationwide.com/urine-drug-testing/) drug tests, which detect recent drug use within days to a week depending on the substance. Hair follicle drug testing is less common in transportation and logistics companies like Roehl because it detects drug use over a longer period (up to 90 days), which may not align with their regulatory or employment screening requirements. Roehl testing mainly uses urine specimens Hair follicle testing detects drug use over 1-3 months Urine testing detects recent drug use, typically 1-7 days For hair follicle drug testing, Roehl employees or contractors would need to seek alternative providers or labs that specialize in this method. AMH Nationwide offers hair follicle testing through a network of five national labs. HAIR FOLLICLE TEST DETAILS ## What is hair follicle drug testing and how does it work? Hair follicle drug testing analyzes a small sample of hair, usually from the scalp, to detect drug metabolites embedded in the hair shaft. This method can detect drug use for approximately 90 days prior to the test. Hair grows about half an inch per month, so labs typically use 1.5 inches of hair to assess three months of drug history. The test is less susceptible to short-term abstinence or dilution attempts than urine testing. [Detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/): up to 90 days Sample: 1.5 inches of scalp hair Drugs detected: opioids, cocaine, amphetamines, cannabinoids, PCP, and others Because hair follicle testing detects long-term drug use, it is often used in forensic, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/), or high-security employment settings rather than routine workplace testing. ROEHL DRUG TESTING ## What drug tests does Roehl use for employee screening? Roehl primarily uses federally compliant urine drug testing aligned with Department of Transportation (DOT) regulations for safety-sensitive positions. This includes a federally certified urine collection protocol under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Urine drug tests detect recent use of substances such as marijuana, cocaine, opiates, amphetamines, and PCP. Roehl may also use breath alcohol testing and other screening methods consistent with DOT requirements. Urine drug testing following DOT protocols Breath alcohol testing No routine use of hair follicle testing For roles not regulated by DOT, hair follicle testing may be used by some employers, but Roehl does not list hair follicle testing as part of its employee screening. LAB NETWORKS ## Who processes Roehl’s drug tests? Roehl’s drug tests are processed by nationally accredited labs that specialize in workplace drug testing. These labs follow strict federal and state regulations to ensure accuracy and reliability. Common labs used include [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Each lab conducts initial screening with confirmatory testing for non-negative results reviewed by a certified Medical Review Officer (MRO). Quest Diagnostics LabCorp Omega Labs United States Drug Testing Labs ExperTox AMH Nationwide works with these same lab networks to provide hair follicle and other drug testing services nationwide. ## Need Hair Follicle Drug Testing?

Hair follicle testing is highly reliable for detecting drug use over an extended period, typically up to 90 days, whereas urine testing detects recent use within days. Hair testing is more difficult to adulterate or cheat, but it cannot detect very recent drug use (within the past week). Urine testing is better for detecting immediate impairment or recent consumption. Hair follicle: detects long-term use, harder to cheat Urine: detects recent use, easier to collect Both require certified labs and MRO review for accuracy Employers choose the testing method based on the detection window needed and regulatory requirements. Roehl’s focus on DOT compliance explains their preference for urine testing. HOW TO TEST ## How can someone get a hair follicle drug test if Roehl does not provide it?

Hair follicle drug tests detect drug use up to 90 days prior to the test, much longer than urine tests which detect recent use within days. Hair follicle tests can detect a wide range of drugs including opioids, cocaine, amphetamines, cannabinoids, and PCP, depending on the lab panel used. All non-negative drug test results from Roehl or AMH Nationwide labs are reviewed by a certified Medical Review Officer (MRO) as part of standard processing.
