The utilization of hair testing has gained momentum as a robust means for identifying drug and alcohol usage. Hair retains long-term markers of alcohol and other drugs, as these indicators become lodged in the fibers of the evolving hair strands. When gathered near the scalp, hair offers up to about a 3-month timeframe for detecting alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.
Acquiring a 1.5-inch segment of around 200 strands of hair (equivalent to the diameter of a #2 pencil) nearest to the scalp yields approximately 100mg of hair, considered the optimal quantity for initial and corroborative testing. For EtG, supplementary analyses, and/or tests exceeding 10 panels, it is suggested to use 150mg of hair. Utilizing a jeweler's scale to weigh the sample is advisable. In cases where scalp hair isn't obtainable, a comparable quantity of body hair might be gathered. References to head hair specifically indicate scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The principal phases in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab's system. This step ensures that the sample was appropriately sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and finalizes any extra data-entry tasks that an electronic chain of custody system may not address.
Screening entails a preliminary rapid assessment for substances of abuse. While screening is an economical method to potentially rule out drug use in most samples, a screen returning positive requires verification for legal admissibility. Samples testing potentially positive at the Screening stage necessitate additional confirmation.
Should a sample emerge as presumptively positive during Screening, more hair is extracted from the initial specimen and primed for the Extraction stage. Here, drugs are drawn from hair at a much lower density than in other methods (e.g., urine or oral fluid), emphasizing the challenging nature of hair-based drug testing.
Confirming any positive screened results is achieved via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with suspected positive outcomes undergo washing before confirmation as required. Each step from Accessioning to Confirmation is evaluated in compliance with the CAP (College of American Pathologists) Hair guidelines and is also aligned with ISO / IEC 17025 accreditation standards.
