Hair Follicle Drug Testing - Peru, MA

What it is, How it works

The evaluation of hair has emerged as a robust method for identifying the usage of drugs and alcohol. Hair captures a historical record of substance consumption by securing biomarkers within its strands as they grow. When gathered near the scalp, hair offers insight into approximately a 3-month window of substance use. The collection process is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of around 200 strands of hair (comparable in thickness to a #2 pencil) situated nearest to the scalp yields 100mg, the optimal quantity for both screening and confirmation. For EtG, additional tests, and evaluations surpassing 10 panels, 150mg of hair is advised. It's best to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair pertain solely to scalp hair. Conversely, body hair encompasses all other categories (such as facial, axillary, etc.).

Process Overview

The core steps in laboratory analysis for drug testing results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial integration of a sample into a laboratory's protocol. This step ensures the sample's packaging integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any manual data entry absent from an electronic chain of custody system.

Screening involves a preliminary examination for substances of abuse. While it’s an economical approach for most samples, a positive indication necessitates confirmation to be admissible in legal proceedings. Samples with presumptive positive results in Screening must undergo secondary confirmation.

For samples flagged as presumptive positives during the Screening phase, additional hair is prepped for Extraction. The extraction concentrates on drugs at a lower concentration than found in other methods (like urine or saliva), emphasizing the complexity of performing hair drug tests.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed as needed prior to confirmation. The complete laboratory procedure from Accessioning through Confirmation is audited under the CAP (College of American Pathologists) Hair standards, along with accreditation under ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations reveal substance use up to 90 days, which is longer than urine tests.
• Challenging to falsify: Hair drug testing proves difficult to manipulate, enhancing result accuracy.
• Provides historical insight: It maps drug consumption patterns over a span, unlike tests focused on recent use.

Limitations:

• Unable to detect recent consumption: Approximately 5-7 days are needed before substances are traceable in hair.
• Expense: Hair testing tends to be pricier compared to other testing methods.
• Variability in outcomes: Hair color and growth rate variability can influence drug metabolite concentrations.

Note: Commonly called "hair follicle tests", these analyses actually assess the hair strand, not the follicle beneath the skin.

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.
