The evaluation of hair has evolved into a significant instrument for identifying drug and alcohol consumption. Hair retains a comprehensive history of these substances by embedding biomarkers within the hair's structure as it develops. By taking samples close to the scalp, one can ascertain drug and alcohol use over a span of up to three months. The collection process for hair is straightforward, it's relatively resistant to tampering, and shipment-friendly.
A segment measuring 1.5 inches and consisting of roughly 200 hair strands (comparable in width to a #2 pencil) positioned nearest to the scalp will equate to 100mg, the preferred amount for both initial and confirmatory analysis. For tests including EtG, add-ons, and panels exceeding ten, a total of 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. In cases where scalp hair is not accessible, an equivalent volume of body hair is acceptable. When referencing head hair, it pertains solely to scalp hair, whereas body hair encompasses all other hair species (including facial and axillary).
Process Overview
The drug testing laboratory processes involve four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary handling of a specimen into the lab's infrastructure. This phase includes checking the sample's seal and shipment, creating a random LAN (Laboratory Accessioning Number), and completing any required data input absent from an electronic chain of custody system.
Screening consists of a preliminary analysis to identify drug abuse. Although Screening serves as an economical method to dismiss drug presence in most specimens, a positive finding must be substantiated to be permissible in legal contexts. Any samples possibly positive require a subsequent confirmation.
In cases of positive indication during Screening, additional hair is retrieved from the initial sample and readied for Extraction. In Extraction, drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluids), presenting challenges unique to hair drug analysis.
Positive screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing before confirmation if necessary. The complete laboratory progression, from Accessioning to Confirmation, is inspected under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
