OVERVIEW ## What is a hair follicle drug test for pre-employment? A hair follicle drug test for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) is a laboratory analysis that detects drug metabolites in a small sample of hair. It identifies drug use typically within the prior 90 days, offering a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. Employers use this test to screen candidates for past drug use before hiring. AMH Nationwide coordinates lab orders that route samples to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. The test requires a hair sample of approximately 1.5 inches in length, collected at an authorized site. TESTING PROCESS ## How does the pre-employment hair follicle test work? The test works by analyzing a small hair sample cut close to the scalp, which captures drug metabolites deposited in hair follicles over time. This sample is sent to a certified lab for testing using validated methods. Non-negative or positive results are reviewed by a certified Medical Review Officer (MRO) to confirm findings and rule out legitimate explanations. This ensures accuracy before results are reported to the employer. Sample Collection: Approximately 100-120 strands cut from head hair Detection Window: Up to 90 days of drug use history Lab Networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, ExperTox MRO Review: All non-negative tests are reviewed by a Medical Review Officer EMPLOYER USE ## Why do employers choose hair follicle tests for pre-employment screening? Employers choose hair follicle drug tests for pre-employment because they provide a reliable, long-term view of a candidate’s drug use history, reducing the risk of hiring individuals who may have recent or chronic substance use issues. The test is less invasive than urine testing and harder to adulterate, offering more confidence in results. It also complies with many company policies requiring extended drug detection. Long detection window up to 90 days Difficult to tamper with or cheat Non-invasive and quick sample collection Professional lab analysis with MRO oversight TEST LIMITATIONS ## What substances does the hair follicle test detect in pre-employment screening? The hair follicle drug test commonly screens for multiple substances including marijuana (THC), cocaine, opiates, amphetamines, methamphetamines, and phencyclidine (PCP). Panels may vary by employer requirements. Detection depends on drug incorporation into hair and the length of hair collected. It does not detect very recent drug use within the past week due to hair growth rates. Marijuana (THC) Cocaine Opiates (codeine, morphine, heroin) Amphetamines and methamphetamines Phencyclidine (PCP) ## Start Your Pre-Employment Hair Follicle Drug Testing Today Contact AMH Nationwide to arrange a hair follicle drug test for pre-employment screening.

DOT AND REGULATIONS ## Is the hair follicle drug test used for DOT-regulated pre-employment screening? No, the hair follicle drug test is not used for Department of Transportation (DOT) regulated safety-sensitive positions. DOT requires urine testing under federally certified protocols as outlined in [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair testing is suitable for non-DOT roles where employers want extended detection of drug use beyond the DOT window.

This includes Medical Review Officer review for any non-negative findings. Hair treatments like bleaching or dyeing may reduce drug metabolite concentrations but do not fully prevent detection. Labs account for hair condition during analysis to ensure accuracy. If head hair is insufficient, body hair may be collected, but detection windows and interpretation differ. Employers should discuss options with AMH Nationwide. Hair follicle testing generally costs more than standard urine tests due to longer detection windows and specialized lab procedures. Pricing varies by panel; call (877) 731-6362 for details. It is very difficult to cheat a hair follicle test because the sample is cut close to the scalp and drug metabolites are embedded inside the hair shaft.
