Hair analysis is now recognized as an effective means for identifying drug and alcohol usage. Hair traps biomarkers within its fibers as it grows, offering a comprehensive timeline of alcohol and drug exposure. When taken from near the scalp, the hair can offer a historical analysis of drug and alcohol use extending up to roughly 90 days. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
Cutting a 1.5-inch piece with approximately 200 hair strands (comparable to the width of a #2 pencil) from the nearest point to the scalp yields 100mg of hair, ideal for initial analysis and confirmation. For EtG assessments, extended panels, or screenings beyond ten panels, a quantity of 150mg is advised. It's best to weigh the sample on a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. References to head hair imply scalp hair specifically. The term body hair encompasses all other hair types (such as facial or underarm hair).
Process Overview
The laboratory processing of drug tests consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the first step of incorporating a sample into a laboratory’s processing workflow. This involves confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody.
Screening includes a preliminary evaluation for drug presence. Although Screening is an efficient method to exclude drug usage in most samples, a positive screen must be confirmed for legal admissibility. Any samples showing presumptive positivity in the Screening phase necessitate a subsequent confirmation step.
In cases where a sample yields a presumptive positive in the Screening, additional hair is extracted from the original specimen for the Extraction phase. Drugs are isolated from hair at notably lower concentrations than with other methods (e.g., urine or oral fluid), which renders hair drug assessment the most complex method to execute.
Verification of any presumptive positive screen is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleansed prior to confirmation if necessary. The comprehensive laboratory procedure from Accessioning through to Confirmation is aligned with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Note: Despite being termed "hair follicle tests," the assessment focuses on the hair strand itself, not the follicle beneath the scalp.
