In recent years, drug testing methods increasingly include hair follicle tests. Employers, courts, and Substance Abuse professionals often prefer hair tests over traditional urine tests. Hair tests are chosen by employers with zero-tolerance policies, legal systems, and probation individuals. The main advantage is hair testing's extended detection window of up to 90 days, through an observed and tamper-resistant process, though urine tests remain the best for uncovering recent drug use within five days.

Hair testing has evolved into a significant method for detecting drug and alcohol consumption. Hair offers a prolonged history of substance use by capturing biomarkers within the fibers of the hair as it grows. Gathering hair near the scalp enables an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to adulterate, and convenient to transport.
A 1.5-inch sample consisting of around 200 hair strands (resembling the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be sampled. When referencing head hair, it pertains strictly to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introductory phase of processing a sample within a lab’s system. This phase incorporates confirming that the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and concluding any supplementary data entry absent in an electronic chain of custody system.
Screening constitutes an initial rapid assessment for drug use. Though cost-effective for ruling out drug usage across most samples, a positive screening necessitates validation for court admissibility. Any samples flagged as potentially positive during Screening demand further confirmation.
Should a sample indicate potential positivity during Screening, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), underscoring the challenge of hair drug screening.
Confirmation for any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
