Hair Follicle Drug Testing - Douglas, OK

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair archives a comprehensive history of alcohol and drug use by embedding biomarkers within the fibers of hair strands. When collected near the scalp, hair offers a detection period of nearly 3 months for tracking alcohol and drugs. Hair is easy to collect, somewhat resistant to tampering, and convenient for transport.

A 1.5-inch segment consisting of roughly 200 hair strands (around the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the preferred amount for analysis and verification. For EtG enhancements and/or examinations exceeding 10 panels, 150mg of the hair sample is advised. It's advised to use a jeweler’s scale for the precise measurement of the sample. If scalp hair is not available, an equivalent quantity of body hair can be used. references to head hair specifically mean scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test outcome involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary entry phase of a sample into a lab’s system, ensuring the sample’s proper sealing and transportation, assigning a random LAN (Laboratory Accessioning Number), and entering any further data not captured by an electronic chain of custody system.

Screening involves an initial rapid assessment for substance abuse. Though Screening economically eliminates drug usage in the majority of cases, a positive outcome in the screen demands further confirmation for it to be legally admissible. Any samples indicating positive results in Screening require subsequent validation.

For samples that test positive in the Screening phase, additional hair is extracted from the primary sample and processed for Extraction. In this process, drugs are isolated from hair at significantly lower concentrations than alternative methods (ex. urine or oral fluid), which contributes to the complexity of hair drug analysis.

Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive are cleansed before confirmation, as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests identify drug use spanning up to 90 days, unlike urine tests which have a shorter detection window.
• Difficulty to cheat: The difficulty in circumventing a hair drug test enhances test accuracy.
• Provides historical data: It reflects a pattern of drug usage over time, rather than just recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Cost: Hair drug assessments tend to be pricier compared to other testing methods.
• Variations in results: Aspects such as hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" is frequently used but the test examines the hair strand and not 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.
