Hair Follicle Drug Testing - Perla, AR

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol usage. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the strands during growth. When sampled near the scalp, it can provide an approximate 3-month window for detecting alcohol and drugs. The collection process is straightforward, with challenges to tamper, and facilitates easy shipment.

A sample measuring 1.5 inches with about 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary tests, or panels exceeding 10, a 150mg specimen is advisable. It's suggested to utilize a jeweler’s scale for weighing. If scalp hair cannot be obtained, a similar amount of body hair can be used. "Head hair" strictly denotes scalp hair, while "body hair" pertains to all other types (like facial or axillary).

Process Overview

The laboratory processing of a drug test result includes four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails integrating a sample into the laboratory's system. It verifies proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary data entry absent in an electronic chain of custody.

Screening serves as an initial assessment for drugs of abuse. Although Screening is a budget-friendly approach for excluding drug usage from most samples, a positive screen necessitates confirmation for court admissibility. Samples deemed positive during Screening require secondary verification.

Should a sample test positive at the Screening phase, additional hair is extracted from the initial specimen for Extraction. This phase involves retrieving drugs from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), making hair drug screening exceptionally challenging.

Confirmation of any positive screening result uses methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The entire process from Accessioning to Confirmation undergoes reviews under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection durations.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, thereby enhancing result accuracy.
• Provides historical data: It offers insight into drug use patterns over time, not just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Cost: Hair drug testing generally incurs higher costs compared to other drug testing methods.
• Variations in results: Drug metabolite concentration in hair is influenced by factors like hair color and individual growth variations.

Note: Although often termed "hair follicle tests", the focus is on analyzing the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to urine tests in Perla, AR, hair tests outperform by providing unmatched 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings.
