Hair Follicle Drug Testing - Ruth, NC

What it is, How it works

Hair analysis is recognized as a significant method for identifying drug and alcohol consumption. Hair strands chronicle long-term drug and alcohol history by embedding biomarkers within the hair fiber matrix. When cut near the scalp, this hair offers a potential detection window of roughly 3 months for alcohol and drug presence. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to dispatch.

A hair segment measuring 1.5 inches, composed of approximately 200 strands (akin to the girth of a #2 pencil) nearest to the scalp delivers 100mg of hair, the standard specimen for screening and corroboration. For tests involving EtG, additional elements, and/or exceeding 10 panels, 150mg of hair is advised. It is advisable to use a jeweler’s scale for weighing. Should scalp hair be unavailable, a proportional volume of body hair can be used. When discussing head hair, it exclusively denotes scalp hair. All other kinds represent body hair (such as facial or axillary hair).

Process Overview

The laboratory analysis of a drug test incorporates four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen within a lab’s system. This phase includes ensuring the specimen was properly sealed and dispatched, allocating an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody framework.

Screening constitutes an initial rapid assessment for illicit substances. While Screening provides a budget-friendly method to exclude drug use in most samples, a confirmed positive is required for legal proceedings. Samples with presumptive positive results during Screening demand subsequent confirmation.

Once a sample yields a presumptive positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. During this process, drugs are removed from hair at concentrations substantially lower than those detected through alternative means (e.g., urine or oral fluids), rendering hair drug assessments challenging.

Any positive outcomes from Screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing as necessary before confirmation. The complete lab process from Accessioning through Confirmation is vetted under the CAP (College of American Pathologists) Hair criteria and certified under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug analyses can identify drug use for as long as 90 days, whereas urine analyses offer a shorter window.
• Difficulty to cheat: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Provides historical data: It evidences drug use patterns over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Drugs require about 5-7 days post-use to be detectable in hair.
• Cost: Hair drug testing is costlier relative to other drug assessment methods.
• Variations in results: Drug metabolite concentrations in hair can be affected by factors like hair color and individual hair growth variations.

Note: The term "hair follicle tests" commonly describes these tests, yet the analysis focuses on hair strands, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Ruth, NC, hair follicle testing outperforms traditional urine testing due to its superior detection capabilities and reliability.

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.
