Hair Follicle Drug Testing - Ocracoke, NC

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol usage. Hair strands capture biomarkers in their fibers, providing a prolonged history of substance use. Sampling hair close to the scalp can yield a detection window of up to approximately three months for alcohol and drugs. Hair is easy to collect, somewhat resistant to tampering, and simple to ship.

A 1.5-inch segment comprising roughly 200 hair strands (around the thickness of a #2 pencil) near the scalp will yield 100mg, the optimal sample for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, a 150mg specimen is advisable. Measuring the specimen on a jeweler’s scale is suggested. If scalp hair is not obtainable, a comparable amount of body hair is viable. In context, head hair indicates scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of drug tests comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates sample processing within a laboratory’s system. This step includes verifying the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input absent in an electronic chain of custody system.

Screening performs a preliminary assessment for drug abuse. Though Screening is an economical methodology to eliminate drug usage in most samples, a positive result needs confirmation to be defensible in legal settings. Samples that are presumptively positive in Screening necessitate secondary confirmation.

For samples deemed presumptively positive during Screening, additional hair is retrieved from the original specimen and prepared for Extraction. During Extraction, drugs are isolated from hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Any positive screening outcome is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results are washed prior to confirmation. From Accessioning to Confirmation, the entire laboratory procedure adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for up to 90 days, whereas urine tests offer a narrower detection timeframe.
• Difficult to manipulate: The accuracy of hair drug tests is higher due to the challenges in evading these tests.
• Provides usage history: It presents a pattern of drug consumption over time, not only recent use.

Limitations:

• Unable to detect recent consumption: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
• Result variability: Elements such as hair color and individual growth rates can influence metabolite concentration in hair.

Note: While commonly called "hair follicle tests," the analysis focuses on the hair strand rather than the follicles 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.
