Hair analysis is recognized as a robust method for identifying substance use. By embedding biomarkers within the structure of the developing hair shaft, hair offers a comprehensive historical record of alcohol and drugs. When taken from near the scalp, hair can indicate drug and alcohol use over a period of up to roughly three months. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (equivalent to a #2 pencil in thickness), nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation tests. For EtG, supplementary tests, or panels exceeding 10, a sample of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not available, a corresponding quantity of body hair can be used. The term head hair specifically means scalp hair, whereas body hair includes all other hair varieties such as facial and axillary.
Process Overview
The core phases in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab’s system. This process includes checking that the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and concluding any extra data input not covered by an electronic chain of custody system.
Screening executes an immediate preliminary test for substances of abuse. While Screening provides a cost-efficient means of eliminating drug use in most samples, a positive screening result must be confirmed for legal admissibility. Samples showing presumptive positives during Screening require a subsequent confirmation.
If a sample shows presumptive positivity in the Screening phase, additional hair from the original sample is prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than seen in other analysis methods (e.g., urine or saliva), making hair drug screening the most complex method to execute.
Positive screening results are confirmed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation as needed. The complete laboratory protocol from Accessioning to Confirmation is evaluated under the guidance of both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
