Hair Follicle Drug Testing - Jolivue, VA

What it is, How it works

The perception of hair testing has evolved into a robust means for uncovering alcohol and drug consumption. Hair strands encapsulate a prolonged narrative of substance usage by holding onto biomarkers within their fibers. When procured near the scalp, a hair sample can reveal alcohol and drug use history spanning up to roughly three months. The collection of hair is straightforward, relatively tamper-resistant, and easily transportable.

Aprox. 1.5 inches of around 200 hair strands (comparable to a #2 pencil size) near the scalp should amount to 100mg, which is the optimal amount for an analysis involving screening and verification. For testing related to EtG, additional evaluations, or tests exceeding 10 panels, it is advisable to have 150mg. Utilizing a jeweler’s scale is suggested for measuring the specimen. In cases where scalp hair isn’t available, body hair of equal measure can be used. References to head hair pertain solely to scalp hair. Body hair encompasses all other varieties such as facial or axillary.

Process Overview

The quintessential four phases in the processing of drug test outcomes in a lab environment consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the primary integration of a sample into a lab's framework, ensuring the sample’s proper sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from an electronic chain of custody system.

Screening represents an initial rapid appraisal for substance misuse. It is a budget-friendly mechanism to eliminate drug use for a large portion of samples, but a positive outcome in Screening mandates confirmation to be legal admissible. Samples indicated as presumptively positive in Screening require additional validation.

Should a sample exhibit a presumptive positive in Screening, additional hair from the initial sample is utilized for Extraction. Here, the extraction of drugs from hair is performed at a notably lower concentration compared to other methods (like urine or oral fluid), which highlights the complexities entailed in hair drug screening.

Confirmation of any positive screen outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive are cleansed before confirmation as necessary. A thorough review of the entire procedure from Accessioning to Confirmation is carried out following CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests are capable of identifying drug consumption for a period of up to 90 days, unlike urine tests with a shorter window.
• Resistance to tampering: The difficulty in maneuvering the results of a hair drug test ensures enhanced accuracy.
• Chronological insight: There’s a provision for discerning a timeline of drug usage over time, extending beyond just recent activity.

Limitations:

• Inability to detect immediate use: Detection in hair materializes after around 5-7 days from consumption.
• Price: Hair drug analysis typically costs more than alternative testing methods.
• Discrepancies in results: Elements like hair color and individual hair growth rates may influence drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests," the actual process examines the hair shaft rather than 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.
