Seen as a potent method for identifying drug and alcohol consumption, hair testing offers a comprehensive history of substance use by capturing biomarkers within the hair strand's fibers. When gathered near the scalp, hair can reveal a detection period spanning up to roughly three months for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp provides 100mg, the optimal sample for both screening and verification. For EtG, add-ons, or analysis beyond 10 panels, a 150mg sample is advised. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair is inaccessible, a similar amount of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into the laboratory’s system. This step ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information entry absent from an electronic chain of custody system.
Screening is a preliminary quick evaluation for drugs of abuse. While Screening is an economical approach to dismiss drug involvement for most samples, a positive outcome must be validated for court acceptability. Any samples that show presumptive positive results in Screening need a follow-up confirmation.
Should a specimen be presumptively positive in Screening, additional hair is extracted from the original sample and readied for Extraction. During this phase, substances are isolated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which contributes to hair drug screening's complexity as a method.
Confirmation of any positive Screening result requires GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive specimens are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.
