Hair Follicle Drug Testing - Fountain Green, MD

What it is, How it works

Hair screening emerged as a vital method for detecting drug and alcohol utilization. Hair serves as a long-term repository for traces of alcohol and drugs by embedding biomarkers within the growing hair strand. When collected near the scalp, it offers a detection window for substances spanning up to roughly three months. The collection of hair is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch portion comprising approximately 200 hair strands (equivalent to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect sample for screening and verification. For EtG, additional assessments, or tests beyond 10 panels, a 150mg sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair cannot be procured, a similar portion of body hair might be used. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair categories (such as facial, axillary, etc.).

Process Overview

The laboratory processing pathway for a drug test outcome incorporates four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial entry of a sample into a lab’s system. This step confirms that the sample was adequately sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and finalizes any outstanding data processing omitted by an electronic custody tracking system.

Screening encompasses an initial rapid assessment for drugs of abuse. While Screening presents a cost-effective means to exclude drug usage in most samples, a positive outcome requires confirmation for legal admissibility. Samples showing a presumptive positive in Screening must undergo a secondary confirmation.

In cases where a sample returns a presumptive positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. During Extraction, drugs are isolated from hair at a notably lower concentration compared to other methods (like urine or oral fluid), hence hair drug screening is the most complex methodology to execute.

Verification of any positive Screening outcome is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show a presumptive positive are cleansed before confirmation as needed. The comprehensive laboratory procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug use over a span of up to 90 days, whereas urine tests possess a narrower detection window.
• Challenging to manipulate: Cheating on a hair drug test is notably difficult, enhancing result accuracy.
• Delivers historical insight: It reveals a pattern of drug consumption over an extended period, not merely recent use.

Limitations:

• Cannot detect recent use: There is a latency of approximately 5-7 days before drugs become discernible in hair.
• Expense: Hair drug evaluations tend to be costlier than other testing techniques.
• Result variability: Factors like hair color and individual hair growth variations can influence the concentration of metabolites in hair.

Note: Although frequently termed "hair follicle tests", the analysis focuses on 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.
