Hair Follicle Drug Testing - Venus, TX

What it is, How it works

Recognized as a potent mechanism for detecting substances, hair screening provides a timeline for drug and alcohol usage by sequestering indicators within hair fibers. Gathering hair near the scalp permits up to a three-month observation duration for detecting alcohol and other substances. The process of acquiring hair is straightforward, moderately resistant to tampering, and convenient for shipping.

Upon extracting a 1.5-inch portion comprising roughly 200 hair strands (comparable to a #2 pencil's girth) near the scalp, it yields 100mg of hair, which serves as an optimal sample for both screening and verification. For assessments involving EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It is optimal to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair is permissible. "Head hair" pertains strictly to scalp hair, while "body hair" encompasses all other variants (facial, axillary, etc.).

Process Overview

The key phases in a laboratory's drug test result processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample within a lab’s system. This entails confirming the sample’s proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any pending data entry absent from an electronic chain of custody framework.

Screening constitutes an initial rapid assessment for substance misuse. While economically efficient for negating drug presence in the majority of samples, positive screening necessitates validation for court admissibility. All samples scoring presumptive positives during Screening mandate subsequent confirmation.

For samples revealed as presumptive positive during Screening, additional hair is drawn from the initial specimen and readied for Extraction. Here, substance removal from hair is at a significantly lower concentration compared to alternative methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Confirmation of positive screening results is executed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing precursory to confirmation as requisite. The extensive laboratory procedure, spanning from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and observance to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can identify drug usage up to 90 days, unlike urine tests that provide a lesser detection timeframe.
• Difficult to manipulate: Cheating with a hair drug test is notably challenging, ensuring result accuracy.
• Chronicles usage trends: It offers insight into habitual drug use over time, beyond recent consumption.

Limitations:

• Inability to capture recent use: It generally requires 5-7 days for substances to become traceable in hair.
• Expense: Hair drug evaluations tend to incur higher costs compared to other test methods.
• Result variability: Elements like hair color and individual growth discrepancies can influence drug metabolite levels within hair.

Note: Although often referred to as "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Venus, TX, hair follicle testing surpasses traditional urine tests for its superior detection accuracy and reliability. Unlike urine tests, hair tests offer a more extensive window for substance detection and are less susceptible to tampering.

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.
