Hair Follicle Drug Testing - Cactus Flats, AZ

What it is, How it works

Through its increasing perception as a robust method for identifying drug and alcohol consumption, hair testing has gained prominence. The strands of hair, by encapsulating biomarkers within their fibers, offer an extended overview of any alcohol and drug intake. When clipped near the scalp, hair can reveal drug and alcohol use for up to a three-month duration. The collection of hair is straightforward, relatively tamper-proof, and easily transported.

An optimal hair collection involves a 1.5-inch portion comprising roughly 200 strands (equivalent to the thickness of a #2 pencil) from close to the scalp, producing 100mg for effective screening and validation. For tests beyond 10 panels, including EtG and additional analyses, 150mg is advised. We suggest using a jeweler’s scale to determine the specimen's weight. Should scalp hair be absent, a similar quantity of body hair could suffice. By head hair, we signify only scalp hair. Meanwhile, body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The lab processing of drug test results entails four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of integrating a sample into the lab's system. This stage includes checks for proper sealing and shipment of the sample, issuing a distinct LAN (Laboratory Accessioning Number), and completing any additional information entry potentially missing from an electronic chain of custody system.

Screening establishes an initial, rapid assessment for substance misuse. While Screening economically dismisses drug use for most samples, a positive screening result necessitates confirmation for court acceptability. Presumptively positive samples found during Screening must undergo a secondary verification.

For samples deemed likely positive at Screening, additional hair from the primary sample undergoes preparation for Extraction. Drugs are extracted from hair at a notably reduced concentration compared to other methods (like urine or oral fluid), underscoring hair testing as the most complex to execute.

The method of Confirmation for any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all samples marked presumptive positive undergo necessary washing. The comprehensive laboratory sequence from Accessioning to Confirmation is regulated by both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Unlike urine tests, hair drug tests can identify drug use spanning up to 90 days.
• Low susceptibility to tampering: The integrity of a hair drug test is challenging to compromise, ensuring reliable results.
• Historical usage assessment: It allows for an analysis of drug consumption patterns over time, not merely recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs become traceable in hair roughly 5-7 days post-consumption.
• Expense: Generally, hair drug tests incur higher costs compared to alternative drug testing approaches.
• Result variance: Attributes such as hair color and individual growth rates can alter drug metabolite concentrations within hair.

Note: Despite commonly being termed "hair follicle tests", the evaluation is conducted on the hair strand 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. 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.
