Hair assessments have emerged as an effective resource in identifying drug and alcohol consumption. Hair archives a prolonged record of substance intake by embedding biomarkers within the hair fiber strands as they grow. When clipped near the scalp, such hair offers a prospective detection duration for alcohol and substances of roughly three months. Collecting hair is straightforward, relatively tough to tamper with, and convenient for transport.
Collecting a 1.5-inch section of nearly 200 hair strands (comparable to a #2 pencil thickness) near the scalp yields about 100mg of hair, which is the optimal sample for both preliminary and confirmatory testing. For EtG, additional analyses, or examinations exceeding 10 panels, a sample of 150mg is advisable. It's recommended to verify the specimen weight using a jeweler’s scale. In cases where scalp hair is inaccessible, an equal measure of body hair might be gathered. References to head hair specify scalp hair alone. Body hair encompasses other hair forms (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial sample processing in a lab’s framework. This phase ensures the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry not accounted for by an electronic chain of custody.
Screening executes an initial swift assessment for substance use. While Screening provides a cost-effective approach for ruling out drug consumption in most samples, a positive result necessitates confirmation for legal acceptability. Samples with presumptive positives in Screening warrant secondary confirmations.
If Screening yields a presumptive positive, additional hair from the original sample undergoes preparation for Extraction. Here, drug substances are retrieved from hair at reduced concentrations compared to other methods (e.g., urine or saliva), underscoring the complexity of hair drug analysis.
Confirmation for any screening positive relies on GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed before final confirmation as required. The entire lab sequence from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 criteria.
