Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a history of alcohol and drugs by capturing biomarkers within the fibers of the growing hair strand. If gathered near the scalp, hair can offer a detection window of up to three months for alcohol and drugs. The collection process for hair is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch sample of roughly 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for evaluation and validation. For EtG, add-ons, and/or assessments above 10 panels, 150mg of the specimen is suggested. It is advisable to measure the specimen on a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair might be utilized. The term head hair refers exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory process of a drug test outcome consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory’s system. This process involves confirming the sample’s proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary method to assess drugs of abuse. While Screening is a cost-efficient manner to exclude drug usage in most samples, a positive screen necessitates confirmation to be acceptable in legal contexts. Any samples that yield presumptive positive results in Screening require an additional confirmation.
Should a sample yield presumptive positive in the Screening phase, further hair is extracted from the original specimen for the Extraction process. In this phase, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to perform.
Confirmation of any positive screening result is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Commonly named "hair follicle tests", the examination evaluates the hair strand, not the follicle beneath the scalp.
