Utilizing hair testing has become recognized as an effective method for detecting drug and alcohol use. As hair grows, it incorporates biomarkers for alcohol and drugs within its fibers, providing an extended historical record. A hair sample taken near the scalp can reveal drug and alcohol consumption history for up to about three months. This method of collection is easy, hard to tamper with, and simple to transport.
Collecting a 1.5-inch segment consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) from next to the scalp yields 100mg, which is optimal for both screening and confirmation tests. For tests involving EtG, more comprehensive panels, or beyond 10 panels, a collection of 150mg is advisable. It is suggested to use a jeweler's scale to weigh the hair. If scalp hair isn't an option, an equivalent quantity of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (like facial or axillary hair).
Process Overview
The laboratory processing of drug tests consists of four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, which integrates the sample into the lab's proceedings. This phase includes ensuring the sample's integrity in terms of sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an electronic chain of custody.
Screening offers a preliminary assessment for common drugs of abuse. Though cost-efficient for eliminating drug misuse in most cases, positive Screens must undergo Confirmation for legal credibility. Samples that screen positive are subjected to further Confirmation testing.
Should a sample test positive during Screening, hair from the original collection is prepared for Extraction. This process pulls drugs from hair at concentrations lower than methods like urine or saliva testing, contributing to the complexity of hair drug testing.
Confirming a positive screen result involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed prior to Confirmation as necessary. The entire lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.
