Does Werner Hair Test? Understand Hair Follicle Drug Testing Benefits
Does Werner hair test for drugs? Werner does not provide direct testing services but may refer clients to labs that perform hair follicle drug tests. Hair follicle drug testing detects drug use over a 90-day window with high accuracy. For lab-directed collection and certified results, call (877) 731-6362.
Does Werner do hair follicle drug testing?
Werner itself is primarily a provider of drug testing services but does not conduct hair follicle drug tests in-house. Instead, drug testing orders are routed through national laboratory networks that perform the analysis.
Hair follicle drug testing is available through the labs Werner partners with, including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. These accredited labs conduct hair drug tests with certified Medical Review Officers reviewing all non-negative results.
What is hair follicle drug testing and how does it work?
Hair follicle drug testing analyzes a small sample of hair to detect drug metabolites incorporated into the hair shaft from bloodstream exposure. This method can detect drug use over approximately 90 days, much longer than urine or saliva tests.
The test is non-invasive and requires about 1.5 inches of hair closest to the scalp. Hair samples are sent to a certified lab for immunoassay screening followed by confirmatory testing using gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Who typically requests hair follicle drug tests through Werner?
Hair follicle drug testing is commonly requested by employers for pre-employment screening, random testing, or post-incident investigations where a longer detection window is needed.
It is also used in legal, probation, and court-ordered testing scenarios to monitor drug abstinence over extended periods. Individuals may request hair drug testing for personal reasons but must follow lab-directed collection protocols.
How does the hair follicle collection process work with Werner testing?
Werner coordinates the lab order and directs the requester to one of over 20,000 nationwide collection sites affiliated with their lab partners. Collection sites perform the hair sample collection under chain-of-custody procedures.
No online ordering is available; all testing must be arranged by phone or through a company representative. After collection, samples are sent to the selected national lab network for analysis.

Are hair follicle drug tests accurate and reliable?
Hair follicle drug testing is highly accurate due to advanced laboratory techniques and confirmatory testing protocols. The use of certified Medical Review Officers ensures that non-negative results are thoroughly reviewed before reporting.
The testing process is standardized and accredited, minimizing false positives. External factors such as passive exposure have minimal impact on results due to metabolite detection rather than parent drug presence.
Can hair follicle drug tests detect single drug use or passive exposure?
Hair follicle testing can detect single instances of drug use if the hair sample represents the period when the drug was consumed. However, detection depends on factors like hair growth rate and drug incorporation.
Passive exposure to drugs like smoke is unlikely to cause a positive hair test because the test identifies metabolites formed inside the body, not just external contamination.
What are the limitations of hair follicle drug testing at Werner labs?
Hair testing cannot detect very recent drug use within the past 5-7 days since hair must grow out to incorporate metabolites. This makes it unsuitable for detecting immediate or short-term drug use.
Certain cosmetic treatments or hair characteristics may affect sample quality but do not typically prevent testing. Detection windows vary by drug and individual hair growth patterns.
Common Questions
Werner does not perform hair follicle drug testing directly. Instead, it routes testing orders to national labs like Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox that provide these services.
Hair follicle drug tests detect drug metabolites incorporated into hair over approximately 90 days, providing a longer detection window than urine or saliva tests.
No, hair follicle testing generally cannot detect drug use within the last 5-7 days due to the time needed for hair growth to incorporate metabolites.
Yes, every non-negative hair drug test result is reviewed by a certified Medical Review Officer as part of the standard testing process.
Certain hair treatments may affect sample quality but typically do not prevent accurate testing. Labs follow strict protocols to ensure reliable results.
