Hair analysis is now regarded as a robust method for identifying drug and alcohol consumption. Hair retains a long-lasting record of alcohol and other substances by holding biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can offer up to nearly a 3-month detection period for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp will provide 100mg of hair, which is the optimal amount for testing and verification. For EtG, additional tests, and/or testing beyond 10 panels, 150mg of the sample is suggested. It is advisable to weigh the sample on a jeweler’s scale. If scalp hair is absent, a similar amount of body hair may be used. When mentioning head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key four phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into a laboratory's system. This step involves confirming that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening includes a quick preliminary check for drug abuse. Although Screening is an economical method for dismissing drug use on most samples, a positive screen must be verified to be legal in court. Samples that are presumptive positives during Screening require secondary confirmation.
If a sample appears positive in the Screening phase, more hair is taken from the initial sample and prepped for Extraction. In this stage, substances are withdrawn from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation, along with compliance to ISO / IEC 17025 standards.
