Hair Follicle Drug Testing - Ligurta, AZ

What it is, How it works

Utilizing hair testing has emerged as an effective approach in determining drug and alcohol consumption. The hair locks in biomarkers within the strands' fibers as they grow, offering a long-term overview of substance use. Collecting hairs nearest to the scalp allows for an alcohol and drug detection period roughly spanning up to three months. The process of collecting hair is straightforward, relatively resistant to tampering, and can be shipped effortlessly.

Obtaining a 1.5-inch segment of around 200 hair strands (similar to the thickness of a #2 pencil) from near the scalp yields 100mg of hair, optimal for both screening and confirmation. In cases of EtG additions or tests exceeding 10 panels, it's best to use 150mg of the sample. Employ a jeweler’s scale to accurately weigh the sample. If scalp hair can’t be sourced, a similar quantity of body hair serves as an alternative. By "head hair," we specifically mean scalp hair. "Body hair" encompasses all other hair types, such as facial and axillary hair.

Process Overview

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

Accessioning marks the first phase where a sample is introduced into the laboratory’s framework. The process validates that the sample is appropriately sealed and dispatched, assigns a Laboratory Accessioning Number (LAN) randomly, and carries out any additional data logging absent in an electronic custody system.

Screening represents the preliminary stage of checking for substance abuse. Though Screening offers a cost-effective strategy to eliminate drug use on the majority of samples, any positive results in the screen must be confirmed for legal acceptance. Those samples with preliminary positive results in Screening require thorough confirmation.

For samples with a presumptive positive in the Screening phase, more hair is extracted from the original sample for the Extraction process. Here, drugs are drawn from hair at notably reduced concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis presents the most complex challenge to execute.

The Confirmation step for every positive screening outcome utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positivity undergo a washing process as needed prior to confirmation. This comprehensive laboratory method from Accessioning to Confirmation aligns with regulations from both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation standards.

Merits of hair drug analysis:

• Extensive detection timeframe: Unlike urine tests with shorter detection spans, hair drug tests detect drug use for up to 90 days.
• Resistance to manipulation: The difficulty in falsifying a hair drug test enhances result accuracy.
• Tracks historical drug use: It offers insight into drug consumption patterns over time, rather than just recent use.

Challenges:

• Incapable of detecting recent consumption: Drugs become identifiable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug screening tends to be pricier compared to other testing techniques.
• Result variability: Elements like hair color and individual hair growth differences can impact the drug metabolite concentration in hair.

Caution: Often termed as "hair follicle tests", the procedure analyses the strand of hair itself, 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.
