Hair Follicle Drug Testing - Avant, OK

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within their fibrous structure, offering a comprehensive timeline of substance use. Collected near the scalp, hair can reveal drug and alcohol usage over nearly a 90-day window. Collection is straightforward, modifying is challenging, and shipping is uncomplicated.

A 1.5-inch segment containing approximately 200 strands of hair (around the thickness of a #2 pencil) nearest to the scalp produces 100mg of hair, which is an optimal portion for initial and confirmatory testing. For tests such as EtG and panels exceeding 10, a specimen of 150mg is advisable. A jeweler's scale is recommended for precise measurement. In the absence of scalp hair, an equivalent quantity of body hair is an alternative. "Head hair" pertains exclusively to scalp hair, whereas "body hair" includes all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial handling of a sample into the lab system. This task ensures that the sample is securely sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any manual data entries missing from electronic custody records.

Screening performs an expedited initial assessment for common substances of abuse. While Screening is cost-efficient for excluding drug use in many samples, a positive result requires confirmation to be legally valid. Samples with preliminary positive results in Screening necessitate a subsequent confirmation.

For samples flagged as presumptively positive during Screening, additional hair is extracted from the initial collection and prepped for Extraction. This phase involves isolating substances from the hair, at a significantly low density compared to other methods (e.g., urine or saliva), contributing to the complexity of hair drug screening.

Positive screening detection undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed as needed before confirmation. The entire laboratory sequence from Accessioning to Confirmation aligns with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug intake up to 90 days, contrasting with urine tests' shorter detection period.
• Resistance to tampering: Manipulating a hair drug test is notably difficult, enhancing accuracy.
• Historical usage patterns: Offers insights into drug usage over time, beyond recent consumption.

Limitations:

• Delayed detection: Substances typically become detectable in hair after 5-7 days.
• Expense: Hair drug testing generally incurs more cost compared to other methods.
• Result variability: Factors such as hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Commonly named "hair follicle tests", the analysis targets 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.
