Hair Follicle Drug Testing - Mechanicsville, MD

What it is, How it works

Recognized as a robust method for identifying drug and alcohol consumption, hair testing uses advancing hair strands to capture biomarkers, offering an extended overview of substance usage. Collection near the scalp allows hair to reveal up to a three-month detection period for alcohol and other drugs. Its collection is straightforward, alterations are challenging, and it is easily shippable.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp delivers 100mg, the optimal amount for both screening and verification. For tests such as EtG, additions, or those surpassing 10 panels, 150mg is advisable. It's recommended to assess the sample weight using a jeweler’s scale. In the absence of scalp hair, a corresponding quantity of body hair can be gathered. "Head hair" strictly signifies scalp hair, while "body hair" encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory examination of a drug test sample encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a specimen undergoes initial handling in a lab’s system. This process includes confirming that it was sealed and dispatched correctly, generating a random Laboratory Accessioning Number (LAN), and completing any additional data input absent in an electronic record of custody system.

Screening consists of a preliminary assessment for illicit substances. While Screening is a cost-efficient approach to exclude drug usage for most specimens, any positive result necessitates confirmation to hold in legal situations. Samples showing a preliminary positive result in Screening undergo further confirmation.

In instances of a presumptively positive Screening, additional hair is extracted from the primary sample for Extraction. In this phase, substances are retrieved from hair at significantly reduced concentration levels than with other approaches (such as urine or oral fluid), highlighting the challenges of executing hair drug screening.

Confirming any positive Screening result involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every sample with a presumptive positive result is cleansed ahead of confirmation as required. The entire progression from Accessioning to Confirmation is scrutinized in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use for up to 90 days, unlike urine tests which offer a smaller detection window.
• Difficulty in manipulation: Cheating a hair drug test is extremely challenging, enhancing the accuracy of results.
• Delivers historical insights: It showcases a drug use pattern over time, rather than only recent usage.

Limitations:

• Unable to determine recent use: It typically takes 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests generally involve higher costs relative to other drug testing techniques.
• Outcome variability: Drug metabolite levels in the hair can vary due to factors such as hair color and individual growth differences.

Note: The term "hair follicle tests" commonly addresses tests of the hair strand, 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.

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
