Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a historical record of substance use. A sample taken from near the scalp can reveal drug and alcohol usage over an approximate three-month period. This method of testing is straightforward to perform, relatively resistant to tampering, and convenient to send for analysis.
Collecting a 1.5-inch section, roughly equivalent to 200 hair strands or the thickness of a #2 pencil, provides 100mg, which is the optimal amount for both initial screening and detailed confirmation. For EtG, additional testing, or examinations exceeding 10 panels, a 150mg sample is advisable. It's beneficial to use a jeweler’s scale for precise measurement. If scalp hair isn't accessible, an equivalent sample of body hair can be taken. "Head hair" specifically pertains to scalp hair, while "body hair" includes all other body locations (such as facial and axillary hair).
Process Overview
There are four principal stages in the laboratory examination of a drug test: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample initially enters the laboratory system. This phase includes ensuring the sample has been appropriately sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and completing any necessary additional data entry not covered by an electronic custody system.
Screening represents an initial, swift evaluation for substance abuse. Though Screening is cost-efficient for excluding drug presence in many samples, results must be confirmed to stand in legal contexts. Samples with a preliminary positive result in Screening need further validation.
If a Screening yields a tentative positive, additional portions of the sample are prepared for Extraction. This process extracts drugs from hair at much lower concentrations compared to other forms like urine or saliva, making hair drug testing a challenging procedure.
Confirming any positive Screening outcome involves using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with preliminary positive results undergo washing before Confirmation if required. The entire laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
