Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair strands offer a comprehensive historical record of substances by encapsulating biomarkers within the hair's growing fibers. When obtained next to the scalp, hair can reveal a detection window for alcohol and drugs extending up to roughly three months. The process of hair collection is straightforward, challenging to tamper with, and convenient for transportation.
A 1.5-inch segment consisting of around 200 hair strands (approximately the size of a #2 pencil) near the scalp yields 100mg, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent measure of body hair is an alternative. When discussing head hair, it specifically pertains to scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into the laboratory’s system. This involves confirming the sample's proper seal and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not covered by an electronic chain of custody system.
Screening offers a preliminary inspection for drugs of abuse. While it serves as a cost-efficient method to eliminate drug use for most samples, a positive screen necessitates confirmation for legal admissibility. Samples with presumptive positive results during Screening mandate further confirmation.
Upon a presumptive positive in Screening, additional hair is sourced from the initial sample and prepped for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Positive screening confirmations occur through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results are washed before confirmation, as required. The complete laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
