Hair examinations have become recognized as an influential means for identifying drug and alcohol consumption. The fibers in growing hair strands capture biomarkers, providing a long-term history of substance intake. When hair is collected near the scalp, it can offer up to a 3-month window for detecting drugs and alcohol. Collecting hair is straightforward, difficult to tamper with, and convenient to transport.
A 1.5-inch sample comprised of roughly 200 hair strands (around the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, add-ons, or tests with more than 10 panels, 150mg of the hair sample is advised. Using a jeweler’s scale to weigh the sample is suggested. In cases where scalp hair isn't available, an equivalent quantity of body hair may be gathered. References to head hair pertain solely to scalp hair, whereas body hair refers to all other types (such as facial and axillary hair).
Process Overview
The primary stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the initial integration of a sample into the system of a laboratory. This step includes ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data input not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substances of abuse. While Screening is a budget-friendly method to exclude drug usage in most samples, a positive screening result must be confirmed for court viability. Any samples potentially testing positive in Screening necessitate further confirmation.
For samples appearing positive in the Screening phase, additional hair is extracted from the collected specimen and readied for Extraction. In this process, drugs are recovered from hair at a much lower concentration compared to alternative methods (like urine or saliva), which is why hair drug analyzing is the most challenging method to execute.
Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All potentially positive samples undergo washing prior to confirmation if needed. The comprehensive laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and certified to ISO / IEC 17025 standards.
