Hair Follicle Drug Testing - Princeton, NC

What it is, How it works

The recognition of hair testing as a formidable method for identifying drug and alcohol intake has grown significantly. Hair offers an extensive timeline of alcohol and drug consumption by encapsulating biomarkers within its fibers as it grows. When obtained near the scalp, hair samples can reveal alcohol and drug usage for up to three months. Hair is straightforward to gather, relatively tamper-resistant, and conveniently transportable.

Gathering a 1.5-inch sample comprising roughly 200 hair strands (about the width of a standard pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for initial and confirmatory analysis. For EtG enhancements or tests exceeding 10 panels, a 150mg specimen is advisable. It is recommended to measure the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be used. "Head hair" refers exclusively to hair from the scalp, while "body hair" encompasses all other types, including facial and axillary hair.

Process Overview

There are four primary stages in the laboratory handling of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage, integrating a sample into the laboratory’s workflow. This phase includes ensuring the sample’s proper sealing and delivery, generating a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry not supplied by an electronic chain of custody mechanism.

Screening offers an expedited preliminary check for substances of abuse. While it presents a budget-friendly option to exclude drug usage for most samples, any positive results during Screening must be verified for legal admissibility. Those samples that yield a presumptive positive in Screening require secondary confirmation.

Should a sample return a presumptive positive at the Screening phase, additional hair is extracted from the initial submission and prepared for Extraction. At this juncture, drug compounds are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive outcomes from Screening are authenticated using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positive results undergo washing before confirmation as necessary. The comprehensive laboratory journey from Accessioning to Confirmation is evaluated in accordance with both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extensive detection span: Hair tests can trace drug use for up to 90 days, contrasting with urine tests, which offer a shorter timeframe.
• Falsification difficulty: The challenge of deceiving a hair test renders the results more trustworthy.
• Retrospective data: These tests offer a timeline of drug consumption over time, beyond just recent usage.

Limitations:

• Absence of immediate detection: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair testing is usually costlier than other methods.
• Result variability: Variables such as hair shade and personal hair growth diversity can influence the presence of drug metabolites in hair.

Note: Despite being commonly described as "hair follicle tests", the analysis examines the hair strand and does not involve the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Princeton, NC, hair follicle testing outshines traditional urine tests by offering superior detection accuracy and reliability.

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.
