Hair Follicle Drug Testing - Lima, IL

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair effectively captures a long-term record of alcohol and substances by embedding biomarkers within the hair fibers as they grow. When retrieved near the scalp, hair can reveal a timeframe of up to three months for detecting alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment comprising around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, a sample of 150mg is advised. It is suggested to use a jeweler's scale for weighing the sample. Should the scalp hair be unavailable, an equivalent portion of body hair is acceptable. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab’s system. This stage verifies that the sample was correctly sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and finalizes any supplementary data entry not covered by an electronic chain of custody system.

Screening constitutes a preliminary rapid analysis for substances of abuse. While it offers a cost-efficient approach to exclude drug use in the majority of specimens, any positive result demands confirmation to be legally valid. Samples with presumptive positive results during Screening necessitate a secondary confirmation.

For samples indicated as presumptive positive in Screening, more hair is extracted from the original specimen for Extraction. This phase involves extracting drugs from hair at a much lower concentration compared to other techniques (e.g., urine or oral fluid), accentuating why hair drug analysis is notably challenging to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation, if necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug consumption for up to 90 days, unlike urine analyses that have a more limited detection period.
• Hard to falsify: Manipulating a hair drug test is quite difficult, enhancing result accuracy.
• Records historical patterns: It chronicles drug usage over a span of time, rather than only recent use.

Limitations:

• Incapable of detecting recent use: It requires around 5-7 days for drugs to register in hair samples.
• Expense: Hair drug evaluations are typically pricier than alternative drug testing techniques.
• Disparities in outcomes: Elements such as hair color and individual variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite often being termed "hair follicle tests", the analysis targets the hair strand rather than 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.

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.
