Hair Follicle Drug Testing - Crescent City, FL

What it is, How it works

Considered a formidable ally in determining substance use, hair testing has garnered significant attention. Hair archives a prolonged record of alcohol and drug consumption by embedding biomarkers within the strands. When trimmed near the scalp, hair reveals an approximate 3-month window of detection for alcohol and drugs. Its collection is straightforward, tampering is less likely, and shipping is hassle-free.

For optimal screening and confirmation, secure a 1.5-inch segment of about 200 hairs (comparable to a #2 pencil) nearest to the scalp, yielding 100mg. For EtG, add-ons, or more than 10-panel tests, a 150mg sample is advised. A jeweler’s scale is recommended for weighing the specimen. If scalp hair isn't an option, an equivalent mass of body hair can be used. When discussing head hair, it pertains exclusively to the scalp, while body hair encompasses other types such as facial and axillary.

Process Overview

There are four primary phases in the lab evaluation of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary incorporation of a sample into a lab's database. This incorporates verifying the intact seal and proper shipment of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing data entry absent from an electronic custody framework.

Screening executes a swift initial assessment for illicit substances. Although cost-efficient for validating drug use absence in most samples, an unfavorable screen requires official validation to be court-worthy. Samples that test positive in Screening necessitate confirmatory analysis.

In cases of a positive Screening result, further hair from the existing sample is procured for Extraction. Here, substances are isolated from hair at considerably lower concentrations compared to other techniques (such as urine or saliva), marking hair drug testing as the most intricate procedure to conduct.

A positive result's Confirmation employs GC/MS, GC/MS/MS or LC/MS/MS methodologies. Presumptive samples undergo washing before Confirmation, if required. The full lab procedure from Accessioning through Confirmation adheres to CAP's (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use up to 90 days, while urine tests have a more limited timeframe.
• Cheating is challenging: Circumventing a hair drug test is quite difficult, enhancing result accuracy.
• Historical data availability: It illustrates a drug's use pattern over time, not just recent consumption.

Limitations:

• Incapacity to detect recent usage: Approximately 5-7 days are needed for drugs to become detectable in hair.
• Expense: Compared to other testing methods, hair drug tests are typically more costly.
• Result variability: Factors like hair color and individual hair growth differences might influence drug metabolite concentrations in hair.

Note: Even though termed "hair follicle tests", the examination focuses on hair strands, not the scalp-embedded follicle.

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.
