Hair testing is recognized as a robust means for identifying drug and alcohol consumption. By embedding biomarkers within the fibers, hair records a long-term use history. When sampled near the scalp, hair can reveal usage patterns for drugs and alcohol over roughly a three-month timeframe. Its collection is straightforward, tampering is challenging, and shipping is convenient.
A sample of 1.5 inches comprising roughly 200 hair strands (equivalent to a #2 pencil) near the scalp provides 100mg, optimal for both screening and confirmation. For EtG, additional tests, or more than 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair is unattainable, body hair of equal volume may be used. References to head hair imply scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing of drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab system, which includes ensuring sample seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not supplied via an electronic chain of custody.
Screening incorporates a preliminary assessment for drugs of abuse. Although cost-efficient for ruling out drug use in most samples, a positive screen necessitates confirmation for court admissibility. Samples with positive screening require secondary confirmation.
Presumptive positives in Screening move to Extraction, where additional hair is prepared. Drugs are extracted from hair at markedly lower concentrations than in urine or oral fluid, making hair drug screening the most complex methodology.
Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All positive specimens are washed pre-confirmation when necessary. The entire lab process, from Accessioning to Confirmation, is reviewed and aligns with CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
