Hair screening has gained recognition as a potent method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within their fibers, offering a long-term record of substance use. When gathered near the scalp, hair can reveal substance use history extending up to 3 months. It is simple to collect, less prone to tampering, and easy to transport.
A 1.5-inch cut of around 200 hair strands (about the thickness of a #2 pencil) near the scalp gives 100mg of hair, optimal for both preliminary and confirmatory testing. For EtG, additional screenings, or extensive tests beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale is suggested to weigh the sample. If scalp hair is not available, a comparable quantity of body hair can be used. By "head hair", only scalp hair is implied. "Body hair" indicates other hair types (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a specimen into a lab's framework. This entails ensuring the sample was sealed and shipped properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data input not managed by an electronic chain of custody protocol.
Screening constitutes a preliminary quick assessment for substances of abuse. Though Screening is economically effective for eliminating drug use in most samples, any positive screen must be confirmed for legal acceptability. Any samples presumptively positive in Screening necessitate further confirmation.
If Screening yields a presumptive positive result, additional hair from the initial specimen is used for Extraction. This phase involves extracting substances from hair at much lower concentrations than other methods (e.g., urine or oral fluid), emphasizing why hair drug screening is the most complex method to execute.
The confirmation of any positive screen occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO/IEC 17025 criteria.
