Hair Follicle Drug Testing - Wilmot, AR

What it is, How it works

Hair testing is viewed increasingly as an effective means for identifying drug and alcohol use. Hair strands capture biomarkers within their fibers, providing a comprehensive record of substance consumption over time. When obtained near the scalp, hair offers a detection period of about 3 months for alcohol and drugs. It's easy to collect, fairly hard to tamper, and simple to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately a #2 pencil's volume) located nearest to the scalp delivers 100mg, which is the optimal amount for analysis and validation. If conducting EtG add-ons and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for accurate measurement. If scalp hair isn't available, a proportional amount of body hair is acceptable. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory drug test process is composed of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage of entering a sample into a lab’s system. It entails ensuring that the sample is correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.

Screening executes a swift initial assessment for drug use. While cost-effective for excluding drug use in most cases, a positive result in Screening necessitates confirmation for courtroom acceptability. Any Screening results marked as presumptive positives require further corroboration.

Should Screening indicate a presumptive positive, additional hair is extracted from the initial batch for analysis in the Extraction phase. Here, drugs are removed from the hair at concentrations lower than those used in other testing methods (e.g., urine or oral fluid), rendering hair drug analysis particularly challenging.

Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a cleansing process before confirmation as warranted. Each aspect of the process from Accessioning to Confirmation is subject to guidelines from both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests that offer a shorter timeframe.
• Difficulty to cheat: Manipulating a hair drug test is considerably challenging, ensuring more reliable results.
• Provides historical data: It presents a history of drug use over time, not solely recent usage.

Limitations:

• Cannot detect recent use: Hair tests require approximately 5-7 days for drugs to register.
• Cost: Generally, hair drug tests come with a higher price point compared to alternative testing options.
• Variations in results: Drug metabolite concentrations may be influenced by hair color and individual growth variations.

Note: Although commonly termed as "hair follicle tests", these examinations actually assess the hair strand, not the underlying hair follicle.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests with traditional urine tests in Wilmot, AR, the former stands out with its superior detection accuracy and reliability.

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.
