Hair analysis is recognized as a vital method for identifying drug and alcohol usage. Hair captures long-term markers of alcohol and drugs by embedding biomarkers within the fibers of the growing strands. When obtained from near the scalp, hair can reveal a window of detection for alcohol and drugs stretching up to around 3 months. The collection of hair is straightforward, relatively resistant to tampering, and convenient for shipping.
A specimen length of 1.5 inches comprising roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for assessment and validation. For EtG, additional tests, and/or extensive panels above 10, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be provided, a comparable amount of body hair may be utilized. When discussing head hair, only scalp hair is implied. Body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The procedure of lab processing for a drug test outcome includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a lab’s framework. This process ensures the sample has been sealed and delivered correctly, allocates a unique LAN (Laboratory Accessioning Number), and completes any necessary data accession absent from an electronic chain of custody format.
Screening conducts a provisional swift assessment for substance abuse. Screening remains an economical approach to exclude drug use in the bulk of specimens, yet a positive finding necessitates confirmation to be permissible legally. Samples showing presumptive positive outcomes require a further validation.
In the event of a presumptive positive result during the Screening procedure, additional hair is extracted from the original sample for the Extraction phase. Here, substances are extracted from hair at significantly lower concentrations compared to other techniques (such as urine or oral saliva), hence making hair drug testing a complex technique to execute.
Verification of any presumptive positive screening finding is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, any samples marked as presumptive positives are washed as needed. The entire lab process from Accessioning to Confirmation undergoes review in alignment with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
