Hair testing is regarded as a robust method for identifying drug and alcohol usage. Hair captures a long-term record of liquor and drug consumption by encapsulating biomarkers in the strands as they grow. When gathered near the scalp, hair can reveal a detection timeframe of up to around three months for substances like alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches composed of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional analyses, and/or screenings involving more than 10 panels, a specimen mass of 150mg is advised. It is suggested to use a jeweler’s balance to weigh the sample. If there is an absence of scalp hair, a comparable amount of body hair may be substituted. The term "head hair" pertains exclusively to scalp hair. "Body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The key sequential steps in the laboratory handling of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s system. This phase entails ensuring that the sample was appropriately sealed and dispatched, generating a unique LAN (Laboratory Accessioning Number), and inputting any supplementary data not supplied by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. Although Screening is an economical approach to negate drug usage in most samples, a positive screening necessitates confirmation for courtroom acceptance. Samples yielding presumptive positives during Screening undergo a secondary confirmation process.
When a sample returns a presumptive positive at the Screening phase, additional hair is extracted from the original sample prepared for Extraction. During this phase, drugs are extracted from the hair at a considerably lower density than with other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples registering presumptive positives are cleaned before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes scrutiny following both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
