Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term profile of substance usage by embedding biomarkers within the growing hair's fibers. When hair is obtained near the scalp, it can offer up to a three-month detection period for alcohol and other substances. The process of hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for screening and verification. For EtG, additional screenings, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the hair using a jeweler’s scale. In situations where scalp hair is lacking, a comparable amount of body hair can be used. Note that head hair exclusively refers to scalp hair, while body hair includes other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test consists of four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step in integrating a sample into a laboratory's system. It involves checking that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and filling in any extra data entry not covered by an electronic chain of custody system.
Screening is designed for an initial rapid assessment of substance abuse. Despite being a cost-efficient method to eliminate drug use in most samples, a positive screening must undergo confirmation before being considered valid in legal proceedings. Samples that yield presumptive positives during Screening require further confirmation.
In cases of presumptive positives in Screening, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluids), which explains why hair drug testing is one of the most challenging practices.
Confirmation of a positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples flagged as presumptive positives are cleansed as necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
