Hair Follicle Drug Testing - Grand Detour, IL

What it is, How it works

The use of hair testing has emerged as a significant method for detecting substance use. Hair serves as a long-standing record of substance intake by embedding biomarkers within the strands during hair growth. When taken close to the scalp, it can reveal substance use over about a 90-day period. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (around the thickness of a #2 pencil) from near the scalp, will yield 100mg of hair, considered the optimal quantity for analysis and verification. For EtG, additional tests, and analyses exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the specimen using a jeweler’s scale. If head hair is not available, the same quantity of body hair can be collected. Reference to head hair implies scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a laboratory’s system. This process involves checking the integrity of the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any missing information not supplied by an electronic chain of custody system.

Screening provides a quick preliminary check for substances of abuse. Although Screening is an economical measure for negating substance use in most cases, any positive screen needs confirmation for legal proceedings. Samples testing presumptively positive during Screening require further validation.

If a sample tests presumptively positive at the Screening phase, additional hair from the initial batch is utilized for Extraction. Here, substances are extracted at lower concentrations compared to other methods (such as urine or oral fluid tests), which is why hair drug screening is considered complex.

The Confirmation phase for any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples undergo washing before confirmation as needed. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, surpassing the shorter detection period of urine tests.
• Hard to falsify: The difficulty in cheating a hair drug test enhances the accuracy of the results.
• Chronological data provision: It offers an overview of drug use trends over time, rather than merely recent activity.

Limitations:

• Inability to detect recent usage: Drugs typically require 5-7 days before becoming detectable in hair.
• Expense: Hair drug tests are typically pricier than alternative testing methods.
• Result variability: Variations in hair color and individual hair growth patterns can affect metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", these tests evaluate the hair strand, 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.
