Hair Follicle Drug Testing - Barre, VT

What it is, How it works

Hair analysis is now recognized as a potent method for identifying substance use. Hair captures a prolonged timeline of alcohol and drug intake by enclosing biomarkers within the strands' fibers. When obtained close to the roots, hair can reveal a detection window of up to roughly three months for substances. Hair is straightforward to gather, somewhat challenging to tamper with, and simple to transport.

A sample 1.5 inches in length consisting of around 200 hair strands (comparable in size to a #2 pencil) near the scalp offers 100mg, which is the preferred quantity for analysis. For EtG, additional tests, and/or screenings over 10 panels, it's advised to use 150mg. We advise measuring the sample on a jeweler’s scale. If head hair is not accessible, an equivalent portion of body hair is acceptable. When we mention head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Procedure Overview

The laboratory steps for processing drug test outcomes consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample within a lab system. This step ensures the sample was securely sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data input that wasn't available through an electronic chain of custody system.

Screening is a preliminary, efficient assessment for drug presence. While it's a budget-friendly approach to dismiss drug use in most samples, a positive indicator requires affirmation to be court-admissible. Any Screening outcome showing presumptive positivity needs subsequent verification.

In cases of presumptive positivity in Screening, more strands are extracted from the initial sample for Preparation. During this phase, the concentration of drugs extracted from hair is significantly lower than other methods (e.g., urine or saliva), which renders hair drug analysis the most intricate to conduct.

Positive Screening confirmations are performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples registering as presumptive positive are cleaned before affirmation as necessary. From the Accessing phase to Confirmation, the complete lab process is reviewed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug assessments can identify substance use over a 90-day span, unlike urine tests with shorter detection periods.
• Challenging to falsify: It is considerably challenging to circumvent a hair drug test, enhancing result reliability.
• Historical consumption insights: It offers insights into consumption trends over time, beyond just recent usage.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug assessments tend to be costlier than alternative testing methods.
• Result variations: Elements such as hair color and personal hair growth rates can influence metabolite levels in hair.

Note: Despite being colloquially known as "hair follicle tests", the examination targets the hair shaft rather than the sub-scalp follicle

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.
