Hair Follicle Drug Testing - Nara Visa, NM

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. By capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive history of alcohol and drugs over extended periods. Collected near the scalp, it can reveal substance use over a period of up to 3 months. Hair is easy to collect, hard to adulterate, and convenient for shipping.

To acquire an ideal sample for analysis, a 1.5-inch segment of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) cut closest to the scalp provides 100mg of hair. For EtG, additional tests, and those exceeding 10 drug panels, 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be taken. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other types, such as facial and axillary hair.

Process Overview

The four primary phases in processing a test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the entry of a sample into a lab's system, ensuring it was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data input missing from an electronic chain of custody.

Screening provides an initial overview for detecting drugs of abuse. Although it serves as a cost-effective measure to dismiss drug presence in most cases, a positive result in Screening must be verified for court admissibility. Any samples that are initially positive in Screening necessitate further confirmation.

Upon a presumptive positive in the Screening phase, more hair is extracted from the initial sample for preparation in the Extraction phase, where drugs are drawn from the hair at concentrations lower than those in other methods (e.g., urine or oral fluid), posing the greatest challenge for hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS techniques authenticate any positive findings from the Screening process. Presumptive positive samples undergo washing before confirmation. Each step, from Accessioning through Confirmation, undergoes rigorous review under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair analysis can detect drug consumption for up to 90 days, in contrast to the shorter span evident in urine testing.
• Challenging to manipulate: The likelihood of tricking a hair drug test is minimal, resulting in more precise outcomes.
• Offers chronological usage data: It reveals a pattern of substance use over time, rather than merely recent usage.

Limitations:

• Cannot identify recent usage: It typically takes about 5-7 days for drugs to integrate into hair, making them detectable.
• Expense: Hair drug testing often comes with higher costs than other testing approaches.
• Variability in outcomes: Factors like hair color and individual growth variations can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests," these analyses evaluate 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
