Hair Follicle Drug Testing - Philipp, MS

What it is, How it works

The utilization of hair analysis is increasingly recognized as a significant means of identifying drug and alcohol consumption. Hair functions as an archival record of alcohol and substance use by incorporating biomarkers within its strands as it grows. A segment of hair taken near the root can typically provide a detection window for substances like alcohol, spanning up to three months. The simplicity of hair collection, its resistance to tampering, and ease of transport contribute to its advantages.

An ideal detection sample consists of a 1.5-inch length comprising approximately 200 hair strands (comparable to a #2 pencil), yielding about 100mg of hair for thorough evaluation. For tests involving EtG, expanded panels beyond ten, or additional analytes, a 150mg hair sample is advisable. We advocate for the specimen's weight assessment using a jeweler's scale. In circumstances where scalp hair is inaccessible, a proportional quantity of body hair is acceptable. The term 'head hair' pertains exclusively to scalp hair, whereas 'body hair' encompasses alternative hair types (e.g., facial, axillary).

Process Overview

The laboratory stages crucial to determining drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the preliminary step in incorporating a sample into a laboratory system, entailing confirmation of proper sealing and shipping, assignment of a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary entries absent from an electronic chain of custody protocol.

Screening provides a swift preliminary assessment for substances of abuse. While economical, positive screenings necessitate subsequent confirmation to hold up in legal proceedings. Any cases indicating a presumptive positive during Screening require further validation.

Should a presumption of positivity arise during Screening, additional hair from the initial sample is processed for Extraction. Here, drugs are derived from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.

The Confirmation stage for any positive outcomes identified during Screening employs technologies such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing prior to confirmation, as necessary. The entire laboratory workflow from Accessioning through Confirmation is evaluated in line with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can identify drug utilization over a 90-day window, contrasting with the reduced timeframe of urine testing.
• Resilience against tampering: Manipulating hair test outcomes proves complex, enhancing result accuracy.
• Retrospective use patterns: Provides insights into long-term drug consumption trends, unlike analyses that only capture recent use.

Limitations:

• Inapt for recent use: Drugs generally require 5-7 days post-use to be traceable in hair.
• Expense: Hair drug assessments generally incur higher costs than alternative methods.
• Result variability factors: Variations in factors such as hair pigmentation and individual growth rates may influence metabolite concentrations within hair.

Note: Despite frequent reference as "hair follicle tests", it is the hair strands rather than the follicles beneath the scalp that are analyzed.

Why Hair Follicle Testing Beats Urine Testing

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
