Hair Follicle Drug Testing - Coulterville, IL

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains biomarkers from alcohol and drugs within the fibers as it grows, offering a detailed long-term history. When gathered near the scalp, hair reveals a detection window extending up to around three months for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg is advised. It's best to verify the specimen's weight using a jeweler’s scale. If scalp hair isn't accessible, a corresponding quantity of body hair is acceptable. By head hair, we mean solely scalp hair. Body hair includes all other kinds of hair (facial, axillary, etc.).

Process Overview

The laboratory drug test result processing comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a lab’s system. This step ensures that the sample arrives sealed and intact, assigns a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry absent from an electronic chain of custody system.

Screening conducts a preliminary assessment for drug abuse. This stage provides a cost-effective measure to exclude drug presence in most samples, though a positive screening demands further confirmation for legal acceptance. Samples with a presumptive positive in Screening require additional confirmation.

For presumptive positives in the Screening process, further hair is extracted from the sample and prepared for the Extraction phase. Here, drug compounds are extracted from hair at concentrations lower than other methods (like urine or oral fluid), which contributes to the complexity of hair drug testing.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as needed. The complete lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair analysis reveals drug usage for up to 90 days, which surpasses the shorter detection period associated with urine tests.
• Hard to tamper with: Cheating a hair drug test is extremely challenging, enhancing the reliability of the results.
• Shows historical usage: It displays a timeline of drug intake rather than just recent activity.

Limitations:

• Cannot detect recent use: Detection of drugs in hair generally requires 5-7 days.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Individual traits like hair color and growth rate can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", this test examines the hair strand and not the follicle beneath the scalp.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
