Hair Follicle Drug Testing - Pearce, AZ

What it is, How it works

Hair analysis is now recognized as an effective means for identifying substance and alcohol consumption. Hair captures biomarkers in its fibers, thus offering an extended timeline of substance use. When obtained near the scalp, hair can indicate alcohol and drug consumption over a period of about three months. Collection of hair is straightforward, challenging to tamper with, and easy to transport.

An optimal sample is a 1.5-inch segment of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, totaling 100mg—ideal for evaluation. For EtG, additional tests, or panels exceeding a count of 10, it is advisable to use 150mg. It is suggested to weigh the sample on a jeweler's scale. If scalp hair is not available, a similar quantity of body hair can be used. The term head hair refers solely to scalp hair, whereas body hair includes all other varieties (facial, underarm, etc.).

Process Overview

The laboratory processing of drug test results encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a specimen in the laboratory system. This step ensures the sample's seal and shipment correctness, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any necessary data entry that is not covered by an electronic chain of custody system.

Screening comprises an initial rapid assessment for substances of abuse. While Screening offers a budget-friendly approach to eliminate drug use in most samples, a positive outcome must be validated for judicial acceptance. Any samples with a presumption of positivity in Screening are subject to additional verification.

Should Screening indicate a presumptive positive, further hair is obtained from the original sample for Extraction. During this phase, substances are retrieved from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluids), signifying the intricate nature of hair drug analysis.

After a positive screening result, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected of being positive undergo washing prior to confirmation if required. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug evaluations can uncover substance use spanning up to 90 days, providing a longer timeframe than urine tests.
• Hard to falsify: It is notably difficult to manipulate a hair drug test, thereby enhancing result accuracy.
• Offers historical insight: The test can depict a pattern of substance use over time, rather than merely current use.

Limitations:

• Cannot pinpoint recent use: There is a 5-7 day timeframe for substances to become evident in hair.
• Price: Hair drug evaluations are typically more costly compared to other testing techniques.
• Result variability: Elements such as hair color and unique differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis is performed on the hair strand itself, not on the 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.

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.
