Hair analysis has become recognized as an effective means to identify substance use. The strands capture and hold biomarkers over time, making hair a repository of alcohol and drug history. When cut near the scalp, it offers a detection window of nearly 3 months for various substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
Gathering a 1.5-inch segment from approximately 200 strands (comparable to a #2 pencil's width) nearest the scalp gives 100mg, which is ideal for preliminary and confirmatory testing. For comprehensive panels like EtG or over 10-panel tests, 150mg of hair is suggested. Utilizing a jeweler's scale for weighing specimens is advisable. If scalp hair is missing, comparable body hair can serve as an alternative. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is logged into the lab’s system. This step ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data not covered by an electronic chain of custody.
Screening is an initial measure to spot substances of abuse. Although cost-efficient for eliminating drug usage in most samples, a positive screen must be verified to stand in court. Samples testing presumptively positive during Screening need additional confirmation.
Presumptive positives from Screening are further prepared by extracting more hair from the sample for Extraction. During this process, substances are isolated from hair at lower levels compared to other methods (like urine or saliva), making hair drug tests intricately challenging.
Confirmation of any positive screening involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation as necessary. Every aspect of the lab process is reviewed under CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
