Hair Follicle Drug Testing - Glencoe, AR

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair stores extended histories of substance use by embedding biomarkers within the growing hair's fibers. When taken from the scalp, hair offers up to a 90-day detection timeframe for substances. It's easy to collect, hard to tamper with, and straightforward to transport.

A 1.5-inch collection of roughly 200 hair strands (comparable in size to a #2 pencil) near the scalp yields 100mg of hair, the prime sample amount for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of hair is advisable. It's best to weigh the sample using a precision scale. If scalp hair isn't available, a similar volume of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (like facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory step, where a sample is incorporated into a lab's system. It involves checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not provided by a digital chain of custody system.

Screening is an initial, swift examination for substance abuse. While it's a cost-effective method to eliminate drug use for most samples, a positive result in Screening needs confirmation for court acceptance. Any samples flagged as potentially positive in Screening require further confirmation.

If a sample appears positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. Here, substances are pulled from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug analysis.

Positive Screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples marked as potentially positive are cleansed as necessary. The complete lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and accreditation standards according to ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage up to 90 days, surpassing urine tests with shorter detection durations.
• Hard to bypass: Cheating a hair drug test is challenging, enhancing result accuracy.
• Chronicles historical consumption: It can illustrate drug usage patterns over time, not just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug testing is typically pricier than alternative testing methods.
• Result variability: Factors such as hair color and individual growth variations can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests", the examination focuses on 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.
