Hair Follicle Drug Testing - Woodruff, SC

What it is, How it works

Utilizing hair testing has emerged as an effective approach for uncovering drug and alcohol consumption. By capturing biomarkers within the strands of hair, it offers an extended timeline of alcohol and drug history. A sample taken near the scalp can reveal substance usage for a timeframe extending up to about three months. The collection process is straightforward, with minimal risk of sample tampering, and it is simple to transport.

Gathering a 1.5-inch section with roughly 200 hair strands (approximating a #2 pencil's size) nearest to the scalp yields 100mg, an optimal quantity for both screening and confirmation. For EtG, additional tests, or panels exceeding ten, a larger sample of 150mg is advised. We suggest using a jeweler’s scale for precise specimen measurement. In cases where scalp hair is not accessible, equivalent quantities of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Conversely, body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The drug testing laboratory undertakes four essential stages in processing results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample’s initial integration into the lab system. This step includes ensuring the sample’s proper sealing and shipping, providing it with a random LAN (Laboratory Accessioning Number), and completing any missing information not supplied by an electronic chain of custody system.

Screening then conducts a swift preliminary examination for substances of abuse. While this cost-effective step helps exclude drug presence in most samples, a positive Screening result demands verification to be legally acceptable. Presumptive positive samples, therefore, necessitate further confirmation.

For samples yielding presumptive positive results during Screening, additional hair from the original sample undergoes preparation for Extraction. In this phase, drug extraction from hair occurs at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), underlining the complexity of hair drug testing procedures.

Verification of any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples with presumptive positive results are washed accordingly. The complete laboratory undergoes a thorough review process from Accessioning to Confirmation, adhering to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests with shorter detection periods, hair drug tests can track drug usage for as long as 90 days.
• Challenging to deceive: Hair drug tests are notably resistant to manipulation, ensuring increased result accuracy.
• Insight into usage trends: They offer insight into patterns of drug usage over time, beyond recent usage alone.

Limitations:

• Inability to detect recent usage: Drugs typically require 5-7 days post-use to become traceable in hair samples.
• Higher costs: Hair drug tests tend to be pricier compared to alternative methods.
• Result variability: Factors such as hair color and individual variations in hair growth can impact drug metabolite concentrations in hair samples.

Note: Commonly termed as "hair follicle tests", these primarily analyze the hair strand itself—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.
