Hair analysis is now considered an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substance intake by embedding biomarkers within the hair strand as it grows. When cut near the scalp, hair can offer a detection range of nearly 3 months for alcohol and various drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
Securing a 1.5-inch length of approximately 200 hair strands (similar to a #2 pencil's thickness) closest to the scalp provides 100mg of hair, the optimum sample size for analysis and verification. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. Using a jeweler's scale for measuring the size is suggested. If scalp hair cannot be obtained, a similar quantity of body hair is permissible. The term head hair pertains solely to scalp hair, while body hair includes all other types (such as facial and axillary hair).
Process Overview
The process of lab processing a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab's system. This process includes checking that the sample is properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any data entry not supported by an electronic custody tracking system.
Screening is a preliminary rapid evaluation for illicit substances. This cost-efficient method helps eliminate drug presence in most samples, though a positive screening result requires further confirmation for legal validation. Samples that test positive provisionally during Screening need a backup verification.
Should a sample indicate a presumptively positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. At this stage, substances are derived from hair at significantly lower concentrations compared to other techniques (like urine or oral fluids), making hair drug screening the most complex technique to execute.
Confirming any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo a cleansing process prior to confirmation when necessary. The comprehensive lab procedure from Accessioning to Confirmation is assessed under the strict guidelines of the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
