Hair Follicle Drug Testing - Horatio Gardens, IL

What it is, How it works

Hair analysis is now acknowledged as a robust method for detecting drugs and alcohol. Hair captures a long-term history of these substances by embedding biomarkers within the fibers of the growing strand. Collected near the scalp, it can reveal substance use over a span of up to three months. Hair sampling is easy to obtain, relatively resistant to tampering, and convenient for transport.

A 1.5-inch hair segment, comprising about 200 strands (roughly equivalent to a #2 pencil), yields 100mg, which is the optimal sample for testing. For EtG extensions or multi-panel tests exceeding 10, 150mg of hair is preferred. Using a jeweler’s scale for accuracy is advised. If scalp hair cannot be collected, an equal quantity of body hair is an alternative. 'Head hair' strictly refers to scalp hair, while 'body hair' encompasses other types like facial and axillary hair.

Process Overview

The four core stages of lab processing for drug testing results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is logged into the lab's system. It involves confirming proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and performing any additional data handling required outside of electronic chain of custody systems.

Screening is a preliminary assessment for substance abuse. Although it provides a cost-effective preliminary analysis, further confirmation is necessary for legal acceptance of positive results. Samples testing presumptive positive in Screening require a confirmatory test.

For presumptive positive results during Screening, additional hair is extracted and processed for an in-depth Extraction phase. Drugs are isolated from hair at significantly lower concentrations compared to other matrices like urine or oral fluid, underscoring the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS methodologies are employed to validate any positive screening outcomes. Pre-confirmation cleaning of presumptive positives is performed as needed. The whole process, from Accessioning through Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation, aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests identify substance use up to 90 days prior, unlike urine tests with shorter durations.
• Resilience against manipulation: Cheating a hair drug test is particularly challenging, thus enhancing result reliability.
• Records historical patterns: It can map drug consumption trends over time instead of just recent use.

Limitations:

• Unable to detect recent use: Detectability in hair only begins approximately 5-7 days post-drug use.
• Cost: Typically, hair drug tests incur higher expenses compared to alternative methods.
• Result variability: Drug metabolite concentrations can be influenced by hair color or individual growth differences.

Note: Though commonly called "hair follicle tests", they actually examine the hair strand rather than the follicle below 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
