Hair Follicle Drug Testing - Great Falls, VA

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol intake. Hair strands capture biomarkers within their fibers, offering an extended timeline of substance usage. Collected near the scalp, hair can reveal drug and alcohol use for up to roughly three months. It's easy to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of around 200 hairs (approximately equal to a #2 pencil's width) near the scalp yields 100mg—the optimal amount for initial and confirmatory testing. For enhanced panels or EtG tests, 150mg is advisable. It is suggested to weigh samples using a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. Only scalp hair is considered as head hair. All other types (like facial or axillary) are categorized as body hair.

Process Overview

The primary stages for processing a drug screen in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, incorporating a sample into the lab’s system. This phase checks the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any manual data entry that an electronic custody chain might miss.

Screening provides an initial, cost-effective assessment for drug presence. While it efficiently rules out use in most samples, a positive result requires confirmation for any legal matters. Those screening positive initially must undergo a secondary verification.

Should a sample screen positively, additional hair is extracted for the Extraction stage. In this phase, drugs are isolated at a considerably lower concentration than in alternative methods (like urine or oral swabs), highlighting why hair drug testing is a complex practice.

Positive findings in screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo cleaning before final confirmation. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accredited to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair tests identify drug use up to 90 days, unlike urine tests with shorter durations.
• Hard to deceive: Cheating a hair drug test is challenging, ensuring higher accuracy.
• History of use: It shows a timeline of consumption not limited to recent activities.

Limitations:

• Limited recent use detection: Drugs take about 5-7 days to be traceable in hair.
• Expense: Generally, hair tests cost more than other methodologies.
• Result inconsistencies: Factors like hair color and growth rates can impact metabolite concentration.

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