Hair Follicle Drug Testing - Frierson, LA

What it is, How it works

The assessment of hair as a method for identifying drug and alcohol consumption has gained recognition as an impactful solution. Hair retains a comprehensive record of alcohol and other substances by capturing biomarkers within its fibers as it grows. When sourced near the scalp, hair can offer a detection timeline of up to approximately three months for alcohol and drugs. This method of collection is straightforward, relatively resistant to tampering, and uncomplicated to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hairs (comparable to the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimum quantity for initial screening and subsequent verification. For EtG assessments, supplementary tests, and analyses beyond 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. Should scalp hair be inaccessible, equivalently measuring body hair may be used. When referring expressly to head hair, it implies scalp hair exclusively. Body hair encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory examination of drug test outcomes is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is processed into a lab’s system. It encompasses confirming the sample’s secure shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any further data recording absent from an electronic chain of custody framework.

Screening serves as an initial rapid evaluation for substances of abuse. While this step is an economical method to eliminate drug use in most samples, a positive screening result must be substantiated to be acceptable in legal settings. Any samples that yield a presumptive positive during Screening necessitate additional validation.

In cases where a sample denotes a presumptive positive at the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. At this stage, drugs are isolated from hair at notably lower concentrations than in other methodologies (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging methodology to execute.

Confirmation of any positive screening result is meticulously undertaken using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all samples presumed positive undergo a necessary washing. Every phase, from Accessioning to Confirmation, is meticulously evaluated in compliance with both the CAP (College of American Pathologists) Hair identification and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair tests can detect drug use for up to 90 days, whereas urine testing offers a shorter detection interval.
• Challenges in tampering: It is exceedingly challenging to alter a hair drug test, resulting in more reliable outcomes.
• Delivers historical insights: It conveys a drug use pattern over time, not merely recent usage.

Limitations:

• Cannot reveal recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair testing typically incurs higher costs compared to alternative drug testing strategies.
• Variability in results: Factors such as hair color and individual growth differences can influence drug metabolite concentration within hair.

Note: The term "hair follicle tests" is commonly used; however, the test actually 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. 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.
