Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drug intake by embedding biomarkers within the fibers of the developing hair strand. When sampled close to the scalp, hair can supply nearly a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches, comprising around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and verification. For EtG, enhancements, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample on a jeweler's scale. If scalp hair is inaccessible, the collection of an equivalent quantity of body hair is feasible. In discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample within a lab's system. This procedure involves ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry not managed by an electronic chain of custody system.
Screening consists of an initial rapid assessment for drug misuse. While Screening is an economical method to negate drug use in most samples, a positive screen necessitates further verification to be permissible in legal proceedings. Any samples that exhibit presumptive positive results in Screening require subsequent confirmation.
Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the challenges of hair drug screening.
Confirmation of any positive screening outcome is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if needed. The lab process from Accessioning to Confirmation is supervised under both the CAP (College of American Pathologists) Hair assignment and the accreditation to ISO / IEC 17025 benchmarks.
