Hair Follicle Drug Testing - Goreville, IL

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair offers an extended historical account of substance use by embedding markers within the strands as hair grows. When clipped near the scalp, hair can reveal a substance use history spanning up to about three months. It is easy to collect, not easily tampered with, and simple to send.

A 1.5-inch length comprising around 200 hairs (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is suggested. Using a jeweler’s scale for weighing the sample is advised. If scalp hair isn’t available, a comparable amount of body hair may be used. By head hair, we mean exclusively scalp hair. Body hair includes all other types (like facial, axillary, etc.).

Process Overview

The four fundamental stages in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase involving the intake of a sample into the laboratory’s protocol. This step ensures that the sample was correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic custody system.

Screening provides a preliminary analysis for the presence of illicit substances. Although Screening is a cost-efficient means of dismissing drug use in the majority of samples, a positive detection must be confirmed for courtroom acceptance. All tentatively positive samples during Screening necessitate further verification.

If Screening suggests positivity, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from the hair at a considerably reduced concentration compared to other methods (e.g., urine or saliva), making hair drug testing exceptionally challenging to execute.

Confirming any initial positive result involves using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo cleansing before confirmation as required. The entire lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair tests can trace drug usage for up to 90 days, whereas urine tests have a more limited range.
• Hard to deceive: Cheating a hair drug test is exceedingly difficult, ensuring more precise results.
• Offers past usage data: Shows a usage pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent usage: It typically takes 5-7 days for substances to be identified in hair.
• More expensive: Hair tests generally cost more than other drug testing techniques.
• Result variations: Elements like hair color and individual growth rates can impact metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the actual analysis is done on the hair shaft rather than the follicle beneath the skin

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.
