Hair Follicle Drug Testing - Wynnburg, TN

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of substance use by locking in biomarkers within its strands as they grow. When collected near the scalp, hair samples can reflect drug and alcohol intake within an approximate three-month timeframe. Collecting hair is straightforward, difficult to tamper with, and easy to transport.

To conduct screening and confirmation, a 1.5-inch segment consisting of around 200 hair strands (similar in size to a #2 pencil) from near the scalp is required to obtain 100mg of hair, which is ideal. For EtG, additional tests, and/or panels exceeding ten, 150mg of the sample is preferred. Utilizing a jeweler’s scale to weigh the sample is advisable. In the absence of scalp hair, equivalent body hair can be collected. When 'head hair' is mentioned, it pertains solely to scalp hair, whereas 'body hair' refers to other types such as facial or axillary hair.

Process Overview

The laboratory process for drug testing consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a laboratory's system. This step ensures the sample was correctly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and finishes any extra data entry not available through an electronic chain of custody.

Screening provides a preliminary assessment for substance abuse. Although Screening is cost-efficient for eliminating drug use in most samples, confirmation of a positive screen is essential for legal admissibility. Any specimens indicating potential positivity during Screening necessitate subsequent verification.

For samples flagged as potentially positive in Screening, additional hair from the initial batch is prepared for Extraction. In Extraction, drugs are derived from hair at much lower concentrations than in other forms like urine or saliva, contributing to the complexity of hair drug testing.

Post-screening, positive results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples presumed positive are washed before confirmation, if necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation as well as according to ISO / IEC 17025 standards.

Benefits of hair drug tests:

• Extended detection timeframe: Hair drug testing can identify substance use for up to 90 days, unlike urine testing, which has a shorter window of detection.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, ensuring more credible results.
• Historical insight: It reveals a consistent pattern of drug consumption over time, not just recent use.

Constraints:

• Inability to detect recent intake: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug testing typically incurs higher costs than other testing approaches.
• Result variability: Elements such as hair color and individual growth differences can influence drug metabolite levels in the hair.

Note: While commonly called "hair follicle tests," the procedure examines the hair strand rather than 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.
