Hair Follicle Drug Testing - North Irwin, PA

What it is, How it works

Hair testing has emerged as a compelling method for detecting drug and alcohol consumption. Hair can capture and store markers of alcohol and drugs within the fibers of the hair as it grows, providing a prolonged historical record. When hair samples are collected from near the scalp, they can offer around a three-month window for detecting alcohol and drug use. Collection is straightforward, tampering is relatively challenging, and samples are easy to transport.

Acquiring a 1.5-inch section of roughly 200 hair strands (approximately the width of a #2 pencil) from the scalp provides 100mg, which is optimal for screening and confirmation. For EtG, additional tests, and panels exceeding 10, a sample of 150mg is advised. It's best to measure the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair may be taken. When we mention head hair, it refers exclusively to scalp hair; body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of integrating a sample into the lab's system. This step ensures the sample was properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and completes any data entry that is not covered by an electronic chain of custody system.

Screening performs a preliminary check for drug abuse. While Screening is a cost-efficient means to exclude drug use in most samples, any positive result must be confirmed to be legally admissible. Samples testing positive in Screening necessitate a secondary confirmation.

For samples testing positive during Screening, additional hair is extracted from the original sample and readied for Extraction. At this stage, detecting drugs from hair involves lower concentrations compared to other methods (like urine or oral fluid), which is why hair drug screening is particularly complex.

Confirmation for any positive Screening outcome uses techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleaned before confirmation if necessary. The entire lab workflow, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use spanning up to 90 days, unlike urine tests, which have a shorter detection period.
• Resistance to tampering: A hair drug test is hard to manipulate, enhancing the accuracy of results.
• Provides usage history: It shows a trend of drug use over a timeframe, rather than pinpointing recent use alone.

Limitations:

• Inability to detect recent use: Detection in hair takes about 5-7 days from initial use.
• Expense: Hair drug testing generally incurs higher costs than other testing techniques.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Despite the frequent reference to "hair follicle tests", the process actually examines 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
