Hair Follicle Drug Testing - Wiederkehr Village, AR

What it is, How it works

Hair testing is viewed as a robust method for detecting alcohol and drug use. It offers a historical overview of alcohol and drugs within the hair strand by capturing biomarkers in the hair fibers. Hair can reveal up to a 3-month consumption timeline for alcohol and drugs if collected near the scalp. It's easy to collect, hard to tamper with, and straightforward to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (approximately matching a #2 pencil's width) close to the scalp provides 100mg, which is optimal for both screening and confirmation. For EtG tests, add-ons, and/or panels exceeding 10, it's advisable to gather 150mg of the specimen. We suggest using a jeweler’s scale for exact measurement. In cases with no scalp hair, equivalent body hair can be gathered. References to head hair specifically denote scalp hair, while body hair pertains to any other hair types (facial, axillary, etc.).

Process Overview

Laboratory processing of drug tests includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial intake of a sample into a lab’s system. It ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional tasks not addressed by an electronic chain of custody.

Screening serves as a preliminary assessment for drugs of abuse. Though cost-effective for clearing most samples of drug use, a positive screen necessitates confirmation for legal admissibility. Samples testing positive during Screening mandate an additional confirmation.

For samples showing a positive result in Screening, more hair is taken from the original sample for the Extraction phase. Here, the drug extraction from hair is at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology.

Confirmation of any positive result in Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing positive are cleaned before confirmation if necessary. The entire lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests offer a detection period lasting up to 90 days, while urine tests offer a narrower window.
• Difficulty to cheat: Cheating on a hair drug test is very challenging, ensuring result accuracy.
• Provides historical data: It reveals drug use patterns over time, not merely recent use.

Limitations:

• Cannot detect recent use: Detection of drugs in hair takes roughly 5-7 days post-consumption.
• Cost: Hair drug tests often cost more than other drug testing methods.
• Variations in results: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", this analysis focuses on the hair strand, not the scalp-buried hair follicle.

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.
