Hair Follicle Drug Testing - Pownal, VT

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair serves as a historical record for alcohol and drug use by retaining biomarkers within the strands. When cut near the scalp, it can reveal drug and alcohol usage for over three months. The hair collection process is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch segment containing around 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg, the preferred quantity for analysis and confirmation. For tests involving EtG, additional screening, or more than 10 panels, 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair might be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other varieties (such as facial or axillary hair).

Process Overview

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

Accessioning entails the initial integration of a sample into a lab’s database. This step checks that the sample was properly sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent in an electronic chain of custody system.

Screening provides a preliminary evaluation for drugs of abuse. While Screening is a cost-efficient means to exclude drug consumption for most samples, a positive screen necessitates confirmation for legal validity. Samples with presumptive positive results in Screening demand further confirmation.

For samples labeled presumptive positive during Screening, additional hair is extracted from the original sample and set for Extraction. This phase involves retrieving drugs from hair at far lower concentrations than other forms (e.g., urine or saliva), thus, making hair drug testing particularly challenging.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo a wash before confirmation, if necessary. The complete laboratory process, starting with Accessioning and ending with Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair program and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use up to 90 days, in contrast to urine tests with a shorter window.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, leading to more reliable results.
• Offers historical insight: It reveals a pattern of drug use over time, not just recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to cost more than alternate testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence the drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Pownal, VT, hair follicle testing offers key advantages over traditional urine tests. The ability to detect substance use over extended periods ensures a more accurate overview.

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.
