Hair examinations have grown in acceptance as an effective method for identifying the consumption of narcotics and alcohol. Hair captures a lengthy timeline of alcohol and drug use by embedding biomarkers within the strands of developing hair. When clipped near the scalp, it can offer a detection timeframe of up to roughly 90 days for alcohol and substance use. Collecting hair is straightforward, relatively resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches with about 200 strands (comparable to a #2 pencil) nearest to the scalp produces 100mg of hair, which is the preferred quantity for both preliminary checks and verification. For EtG, supplementations, and/or assessments beyond a 10-panel level, it is advised to have 150mg of the sample. Utilizing a jeweler’s balance to weigh the specimen is encouraged. Should scalp hair not be accessible, an equivalent volume of body hair can be utilized. By head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory assessment of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample into the laboratory's database. This procedure ensures that the sample was sealed and delivered accurately, provides a unique LAN (Laboratory Accessioning Number), and includes any further data input not available through an electronic chain of custody mechanism.
Screening involves a preliminary rapid analysis for substances of abuse. While it is financially efficient to eliminate drug use in most samples through Screening, a positive result necessitates verification for acceptance in legal proceedings. Any samples flagged as presumptively positive in Screening mandate additional confirmation.
Should a sample test positive at the Screening stage, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are drawn from hair at significantly reduced concentrations compared to other techniques (like urine or oral fluids), explaining why hair drug analysis is the most complex to execute.
Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Every presumptive positive specimen undergoes washing as required prior to confirmation. The full laboratory operation from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.
