Hair Follicle Drug Testing - Norphlet, AR

What it is, How it works

Considered a robust method for identifying drug and alcohol presence, hair testing offers a comprehensive long-term analysis by capturing biomarkers within the strands. Hair obtained near the scalp can yield a detection window extending up to roughly three months for substances. The collection process is straightforward, the potential for alteration is minimal, and the shipping process is uncomplicated.

A 1.5-inch segment consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for evaluation and validation. For tests including EtG, additional substances, and those surpassing 10 panels, 150mg is advisable. We suggest weighing the hair sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair may be used. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses other types like facial or axillary hair.

Process Overview

The laboratory drug test result processing involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes integrating a sample into a lab’s system. This step assures the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fulfills any additional data entry lacking in an electronic chain of custody system.

Screening offers an initial swift examination for substance abuse. Despite being a cost-effective means to dismiss drug usage in most samples, a positive screen requires validation to be court-admissible. Any probable positive outcomes in Screening necessitate a follow-up confirmation.

For samples marked as presumptively positive during Screening, further hair is extracted from the original sample and readied for Extraction. At this phase, drugs are retrieved from hair at significantly lower concentrations compared to other methods like urine or oral fluid, underscoring the complexity of hair drug screening.

Confirmation for any presumptive positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples undergo washing as needed. The entire process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for as long as 90 days, whereas urine tests offer a narrower detection timeframe.
• Difficulty to cheat: Hair drug tests are notably hard to manipulate, enhancing result reliability.
• Provides historical data: Offers insight into drug usage patterns across time, rather than just recent utilization.

Limitations:

• Cannot detect recent use: Drugs generally take 5-7 days to become noticeable in hair.
• Cost: Hair drug testing is typically costlier compared to other methods.
• Variations in results: Variables like hair color and individual hair growth disparities can influence drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the analysis targets the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
