Hair Follicle Drug Testing - Sibley, MS

What it is, How it works

Hair testing is increasingly recognized as a robust instrument for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the fibers of the growing strand. When taken close to the scalp, hair offers approximately a 3-month detection window. It is effortless to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch hair sample from about 200 strands near the scalp amounts to 100mg, which is perfect for screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the specimen is advisable. Using a jeweler’s scale for weighing is suggested. In the absence of scalp hair, an equivalent amount of body hair can be gathered. 'Head hair' specifically means scalp hair. 'Body hair' covers all other types (such as facial, axillary, etc.).

Process Overview

The four core steps in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the sample's initial processing into the laboratory system. This step involves ensuring the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry absent from an electronic chain of custody system.

Screening involves a preliminary examination for substance abuse. Although it's a cost-efficient method to dismiss drug usage in most samples, confirmed positive results are necessary for legal admissibility. Samples found presumptively positive in Screening must undergo a secondary confirmation.

For a presumptively positive result in Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or oral fluids), making hair testing the most challenging to execute.

Confirming a positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleaned pre-confirmation as needed. The total laboratory procedure from Accessioning to Confirmation undergoes review under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing identifies substance use up to 90 days; contrasting urine tests have a shorter detection span.
• Difficulty to cheat: Cheating a hair drug test proves highly challenging, enhancing result accuracy.
• Provides historical data: It traces a timeline of drug usage, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after about 5-7 days.
• Cost: Hair testing typically incurs higher expenses than other methods.
• Variations in results: Variables like hair color and individual growth can influence metabolite concentrations in hair.

Note: Despite its common reference as "hair follicle tests", the analysis focuses on the strand, not 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
