Hair Follicle Drug Testing - Rewey, WI

What it is, How it works

Identified as a significant resource, hair testing is utilized for discerning alcohol and drug consumption by embedding biomarkers in the hair's structure. A specimen obtained near the scalp grants a detection span for alcohol and drugs extending up to roughly three months. Hair samples are straightforward to gather, hard to tamper with, and convenient to send.

An optimal 1.5-inch segment comprising around 200 hair strands (approximately equivalent to a #2 pencil's diameter) closest to the scalp yields 100mg, ideal for analysis. For assessments like EtG, supplementary tests, and panels exceeding ten, a 150mg sample is advised. Measuring the sample's weight on a jeweler’s scale is suggested. If scalp hair is absent, an equivalent volume of body hair may be used. "Head hair" pertains exclusively to scalp hair, whereas "body hair" encompasses all other types like facial and axillary hair.

Process Overview

In a laboratory, the drug test procedure encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab’s data system, ensuring the sample is properly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and completing additional data entry not fulfilled by an electronic chain of custody.

Screening involves an initial assessment for substances of abuse. Though cost-efficient for ruling out drug usage in most samples, a screening positive necessitates confirmation for court admissibility. Samples showing potential positivity in Screening require confirmation.

Should Screening indicate a positive result, additional hair is drawn from the primary sample and readied for Extraction. Here, the concentration of extracted drugs from hair is significantly lower than other methods (e.g., urine or oral fluid), making hair drug screening the utmost challenging method to conduct.

Confirmation of a positive screen is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The comprehensive process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can track drug usage up to 90 days, offering a longer window than urine tests.
• Challenging to manipulate: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Tracks historical usage: It charts a drug use pattern over time, beyond immediate use.

Limitations:

• Inability to capture recent consumption: Detection in hair begins approximately 5-7 days after use.
• Expense: Hair drug tests generally incur higher costs compared to alternative methods.
• Result variability: Factors like hair color and personal hair growth patterns can influence drug metabolite levels in hair.

Note: Frequently called "hair follicle tests," the analysis is performed on the hair strand, not the follicle itself.

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.
