Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair serves as a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer up to roughly a 3-month timeframe for detecting alcohol and other substances. The collection process is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
A 1.5-inch sample of around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair isn’t available, a comparable quantity of body hair can be collected. When mentioning head hair, it exclusively refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary procedural phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the preliminary processing of a specimen into a laboratory’s infrastructure. This encompasses ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody framework.
Screening pertains to an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient strategy to eliminate drug consumption in the majority of samples, a positive result necessitates confirmation for it to be legally presented in court. Samples with presumptive positive results in Screening require a follow-up confirmation.
If a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at notably lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to execute.
Confirmation of any positive Screening findings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before Confirmation, as needed. The entire laboratory workflow from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
