Hair Follicle Drug Testing - Charlo, MT

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. It offers a historical overview of substance consumption by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, this method can deliver a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper, and simple to transport.

A sample of 1.5 inches comprising around 200 strands (comparable in size to a #2 pencil) taken nearest the scalp yields 100mg, which is ideal for analysis and verification. For EtG, additional tests, or more than 10-panel tests, 150mg is advised. We suggest using a jeweler's scale to measure the specimen's weight. If scalp hair is unavailable, an equivalent quantity of body hair can be used. When discussing head hair, we mean scalp hair specifically. Body hair pertains to all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a lab's system, ensuring the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not available through an electronic chain of custody system.

Screening offers a preliminary assessment for substance abuse. Although Screening is cost-effective for ruling out drug use in most samples, court-admissible results require confirmation of a positive screen. Hence, samples showing presumptive positives in Screening necessitate secondary confirmation.

If a sample shows a presumptive positive during Screening, more hair is extracted from the original sample for the Extraction process. Here, drugs are extracted at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening notoriously challenging.

Positive screening confirmations are made using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample showing a presumptive positive is appropriately washed before confirmation. The complete process from Accessioning to Confirmation follows both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can detect drugs for as long as 90 days, contrasting with urine tests, which have a shorter detection period.
• Highly resistant to tampering: It is very challenging to compromise a hair drug test, guaranteeing more accurate outcomes.
• Chronological usage data: It provides a pattern of substance use over time, not just recent usage.

Limitations:

• Undetectable recent usage: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug screenings are usually more costly than other testing options.
• Result variations: Elements like hair color and personal hair growth differences can alter drug metabolite concentrations.

Note: Although referred to as "hair follicle tests," the analysis pertains to the hair 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.
