Hair Follicle Drug Testing - Sam Rayburn, TX

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. It offers a comprehensive overview of alcohol and drug intake by capturing markers within the developing hair strand's fibers. When gathered from near the scalp, hair can provide an approximate 3-month timeframe for detecting alcohol and substances. The collection of hair is straightforward, moderately challenging to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (akin to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal quantity for testing and confirmation. For EtG, additional tests, or any that exceed 10 panels, 150mg is advised. It’s suggested to measure the sample using a jeweler’s scale. If scalp hair isn’t accessible, a similar quantity of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The key stages in processing a drug test result in the laboratory consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab’s system, which includes checking that it was sealed and delivered correctly, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any unprovided data entry not available through an electronic chain of custody system.

Screening involves a rapid assessment to detect drug abuse. Although it's a cost-efficient approach to rule out drug use for most samples, a positive screen must be verified for it to be court-admissible. All samples preliminarily positive in Screening need additional confirmation.

If Screening suggests a sample is positive, more hair is extracted from the initial batch for Extraction. This step involves isolating drugs from hair at much lower concentrations than other methods such as urine or oral fluid, contributing to hair drug testing's reputation as the most challenging method.

Positive Screening results undergo Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptively positive samples are washed as needed. Each stage from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests that have a shorter timeframe.
• Hard to deceive: Cheating a hair drug test is exceptionally difficult, enhancing result precision.
• Offers historical insight: It can reveal patterns of drug use over time rather than just new use.

Limitations:

• Cannot detect recent use: Drugs require approximately 5-7 days to be traceable in hair.
• Expense: Hair drug tests are usually pricier than other screening methods.
• Result differences: Elements such as hair color and individual growth variations can influence drug metabolite levels in hair.

Note: Despite being called "hair follicle tests", the analysis evaluates 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. 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.
