Hair Follicle Drug Testing - Harriet, AR

What it is, How it works

Hair testing is increasingly recognized as a potent means for identifying drug and alcohol consumption. The hair incorporates a longitudinal record of alcohol and other substances by embedding biomarkers within its growing fibers. When gathered near the scalp, hair offers an estimated 3-month detection timeframe for alcohol and other substances. It’s easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch section consisting of roughly 200 hair strands (akin to the width of a #2 pencil) near the scalp yields 100mg of hair—the optimal quantity for analysis and confirmation. For EtG, enhancements, and/or screenings beyond 10 panels, 150mg of hair is advised. Measuring the sample with a jeweler’s scale is recommended. Should scalp hair be unavailable, an equivalent portion of body hair may be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The primary stages in processing a lab-based drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the first phase of entering a specimen into a lab’s system. This entails making sure the sample was adequately sealed and delivered, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening entails an initial brief assessment for substance misuse. Although Screening is a budget-friendly approach to discount drug use in most specimens, a positive screen necessitates confirmation for court admissibility. Samples showing presumptive positivity in Screening must undergo secondary confirmation.

In instances where a sample yields a presumptive positive at the Screening phase, further hair is extracted from the primary specimen to prep for Extraction. At this juncture, substances are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underpinning the complexity of hair drug screening.

Verifying any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive specimens are washed as necessary. The complete lab process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations ascertain drug use over an approximate 90-day span, contrasting with urine exams that possess a briefer detection duration.
• Challenging to falsify: The difficulty in deceiving a hair drug test contributes to more precise results.
• Reveals historical patterns: It offers insights into the trajectory of substance use over time, not solely current use.

Limitations:

• Incapable of identifying recent usage: Detection of drugs in hair takes around 5-7 days.
• Expense: Hair drug tests typically incur higher costs compared to other drug testing methodologies.
• Result variabilities: Influences such as hair pigment and individual hair growth variations may impact drug metabolite levels in the hair.

Note: Despite being commonly called "hair follicle tests", the analysis is on the hair shaft, 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.
