Hair analysis is increasingly recognized as an effective mechanism for identifying drug and alcohol consumption. Hair retains a comprehensive history of substance use by embedding biomarkers within its fibers. When collected near the scalp, it can offer a detection timeframe for alcohol and drugs extending up to around three months. Hair collection is straightforward, not easily tampered with, and convenient to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for testing and verification. For EtG, additional elements, or analyses exceeding 10 panels, 150mg is advisable. The specimen should be measured using a jeweler’s scale. If scalp hair isn't accessible, equivalent body hair can be gathered. Here, ‘head hair’ pertains specifically to scalp hair, whereas ‘body hair’ includes all other varieties (such as facial and axillary hair).
Process Overview
The principal phases in the laboratory processing of drug testing results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial integration into the laboratory's system. This step verifies the sample’s proper sealing and shipping, allocates a random Laboratory Accessioning Number (LAN), and addresses any further data entry not managed by an electronic chain of custody system.
Screening provides a preliminary assessment for substance abuse. Though economical for excluding most drug use instances, positive screening results must be validated for legal admissibility. Samples flagged as potentially positive in Screening require additional confirmation.
If Screening indicates a potential positive, additional hair is extracted from the primary sample and prepared for Extraction. This step isolates drugs from hair at substantially lower concentrations than other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
To confirm any positive results from Screening, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Pre-confirmation washing of all potential positive samples occurs as needed. The complete laboratory process, spanning from Accessioning to Confirmation, undergoes scrutiny according to both the College of American Pathologists (CAP) Hair designation and accreditation standards of ISO / IEC 17025.
