Does Roehl Conduct Hair Follicle Drug Tests? Understanding Their 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 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.

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.

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.

Because hair follicle testing detects long-term drug use, it is often used in forensic, probation, or high-security employment settings rather than routine workplace 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.

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.

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.

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, LabCorp, 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).

AMH Nationwide works with these same lab networks to provide hair follicle and other drug testing services nationwide.

How reliable is hair follicle testing compared to urine 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.

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 can someone get a hair follicle drug test if Roehl does not provide it?

If you need a hair follicle drug test and Roehl does not offer it, you can contact AMH Nationwide to arrange testing at one of over 20,000 collection sites across the US.

AMH will provide the lab order and direct you to a nearby collection site within the national lab networks including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.

There is no option to order testing online; you must call to schedule and receive the lab order. Call (877) 731-6362 to start the process.
