Hair Follicle Drug Testing - Sherwood, MD

What it is, How it works

Recognized as an effective method, hair testing is utilized for detecting the presence of drugs and alcohol. The hair captures a lasting record of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair samples can reveal substance intake for up to three months. The collection process is straightforward, resistant to tampering, and convenient for shipping.

A 1.5-inch section containing approximately 200 hairs (similar to the thickness of a #2 pencil) from close to the scalp yields 100mg of hair, the recommended amount for initial testing and verification. For EtG, additional testing, and tests beyond 10 panels, 150mg is suggested. Utilizing a jeweler’s scale to weigh the sample is advised. In the absence of scalp hair, an equivalent quantity of body hair can be used. The term head hair solely refers to scalp hair, while body hair encompasses all other types such as facial and underarm hair.

Process Overview

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

Accessioning involves recording the sample in the lab’s system initially. This step includes confirming the sample's integrity and proper shipping, assigning a unique LAN (Laboratory Accessioning Number), and performing any necessary manual data entry not covered by an electronic chain of custody.

Screening involves an initial assessment for drug presence. While cost-effective and efficient for most samples, a positive screen requires confirmation for legal validity. Samples that show a presumptive positive result in the Screening require a follow-up confirmation.

When a sample tests presumptively positive at the Screening stage, more hair is extracted from the original collection for further analysis. Here, hair is subjected to Extraction, where substances are isolated at lower concentrations than other methods (such as urine or saliva testing), making it the most challenging method to implement.

To validate any positive results from Screening, methods like GC/MS, GC/MS/MS, or LC/MS/MS are utilized for Confirmation. Samples that are presumptive positive undergo necessary washing before confirmation. The entire process, from Accessioning to Confirmation, is assessed in compliance with CAP (College of American Pathologists) Hair accreditation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drugs for up to 90 days, surpassing the shorter detection period of urine tests.
• Effective accuracy: Due to its robustness, cheating a hair test is notably challenging, leading to more reliable results.
• Chronological substance use data: Hair testing offers insights into patterns of drug use over time, beyond recent intake.

Limitations:

• Inability to detect recent usage: Drugs take roughly 5-7 days to become traceable in hair strands.
• Expense: Hair drug testing tends to be pricier than alternative methods.
• Result variability: Drug metabolite concentrations can be influenced by factors like hair color and individual growth rates.

Note: Though often called "hair follicle tests", the analysis focuses on the strand above the scalp, not the follicle beneath it.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
