Hair Follicle Drug Testing - Enosburg Falls, VT

What it is, How it works

Hair analysis is increasingly regarded as a potent method for identifying drug and alcohol consumption. Hair strands encapsulate a prolonged record of substance use by embedding biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair samples can offer a detection timeframe for alcohol and drugs of up to roughly three months. Hair collection is straightforward, less susceptible to tampering, and easily transportable.

Collecting a 1.5-inch segment of about 200 hair strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation procedures. For EtG, additional screening, and/or evaluations beyond 10 panels, a 150mg specimen is advisable. It's best to measure the specimen using a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair is a suitable alternative. 'Head hair' specifically refers to scalp hair, while 'body hair' encompasses all other hair types (like facial or axillary hair).

Process Overview

The key phases in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial entry into a lab's system. This phase verifies the sample's proper sealing and transportation, assigns a random LAN (Laboratory Accessioning Number), and completes supplementary data input not available through an electronic chain of custody infrastructure.

Screening entails carrying out a swift preliminary assessment for common drugs of abuse. Although cost-effective for excluding drug use across most samples, a positive screen demands confirmation for legal admissibility. Samples showing presumptive positives in Screening necessitate follow-up confirmation.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening exceptionally challenging.

Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS processes. All samples that show presumptive positives undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation falls under the scrutiny of both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a 90-day span, unlike urine tests which offer a narrower detection period.
• Hard to deceive: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Displays drug use patterns: It reveals usage trends over time, rather than just recent consumption.

Limitations:

• Lacks detection of recent use: Drugs appear in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences influence drug metabolite concentration in the hair.

Note: Despite being referred to as "hair follicle tests", the analysis actually examines the hair strand and 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.
