Hair assessments are increasingly acknowledged as significant instruments for identifying drug and alcohol intake. Hair offers an extended record of alcohol and other substances by embedding biomarkers within the strands of the developing hair. When gathered near the scalp, hair can offer up to a roughly 3-month window for identifying alcohol and other substances. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and validation. For EtG, additional tests, and/or screenings surpassing 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample with a jeweler’s scale. If scalp hair is not accessible, a similar amount of body hair might be gathered. When mentioning head hair, we imply scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary four phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the primary processing of a sample into a laboratory’s database. This involves confirming that the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input absent in an electronic chain of custody system.
Screening includes an initial rapid assessment for drugs of abuse. While Screening is an economical method to exclude drug use in most samples, a positive result must be validated to be acceptable in legal proceedings. Any samples that return a preliminary positive result in Screening necessitate secondary validation.
If a sample returns a preliminary positive in the Screening phase, additional hair is withdrawn from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations than other approaches (e.g., urine or oral fluid), which is why hair drug screening is among the most complex methodologies.
Verification of any positive Screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All preliminary positive samples undergo washing before validation if necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the certification to ISO / IEC 17025 standards.
