Hair Follicle Drug Testing - Stock Island, FL

What it is, How it works

Hair analysis is now recognized as a potent means for identifying drug and alcohol consumption. It captures a prolonged timeline of these substances by embedding biomarkers within the fibers of the hair as it grows. When strands are extracted near the scalp, they can offer a detection window for alcohol and other drugs extending up to roughly 90 days. Hair sampling is straightforward, relatively challenging to tamper with, and convenient for shipping.

A sample size of 1.5 inches with approximately 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp will yield 100mg of hair, which is the preferred amount for both screening and confirmation. For extended tests like EtG add-ons or 10+ panel examinations, a specimen amount of 150mg is advisable. Using a jeweler’s scale is suggested for weighing the specimen. If scalp hair isn’t available, a similar volume of body hair can be utilized. When we mention head hair, we refer specifically to scalp hair. In contrast, body hair encompasses all other types like facial, axillary, etc.

Process Overview

The key stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the primary processing step that integrates a sample into a lab’s database. This step ensures that the sample is sealed correctly, shipped as required, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data entry absent in an electronic chain of custody system.

Screening performs an initial cursory analysis for substance abuse. While Screening provides a cost-efficient method to dismiss drug usage in most samples, any positive finding necessitates confirmation for legal admissibility. Samples yielding a positive result at Screening need subsequent confirmation.

For samples deemed presumptively positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are retrieved from the hair at notably lower concentrations compared to other tests like urine or saliva, underscoring the complexity of hair drug testing.

Confirmation of positive screening results is executed using GC/MS, GC/MS/MS or LC/MS/MS. Needed samples are washed before confirmation. The entire lab workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can track drug use for up to three months, unlike urine tests with shorter spans.
• Tough to circumvent: Hair testing is hard to manipulate, thus the results hold greater validity.
• Delivers longitudinal data: It can illustrate drug usage patterns over time, rather than only recent use.

Limitations:

• Cannot track recent consumption: Detection in hair takes roughly 5-7 days after use.
• Expense: Hair testing typically incurs higher costs than other methods.
• Result variability: Factors such as hair color and individual growth may influence drug metabolite concentrations in hair.

Note: Although occasionally termed "hair follicle tests," the analysis is conducted on the hair strand 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.
