Hair Follicle Drug Testing - Danville, VT

What it is, How it works

Viewed as an effective resource, hair analysis aids in identifying drug and alcohol consumption. The hair captures a detailed timeline of substance use by embedding biomarkers within the hair's growing fibers. When taken near the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

Collecting a 1.5-inch length, approximately 200 strands of hair close to the scalp (roughly the thickness of a #2 pencil), yields 100mg of hair, ideal for both screening and test confirmation. For testing such as EtG, add-ons, and where tests exceed ten panels, 150mg of the sample is suggested. We advise using a jeweler’s scale for weighing. If scalp hair is non-existent, a comparable amount of body hair is collectable. When mentioning head hair, it strictly refers to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory drug testing process involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial laboratory system processing. This step ensures the sample is duly sealed and dispatched, assigns a unique Laboratory Accessioning Number (LAN), and finalizes any extra data input not covered by an electronic chain of custody.

Screening executes an initial, rapid drug abuse check. While cost-efficient for reaffirming non-usage in most samples, positive screenings necessitate confirmation for court admissibility. Any samples showing presumptive positives in Screening require subsequent verification.

A presumptive positive outcome in the Screening necessitates drawing additional hair from the primary sample for Extraction. This phase involves extracting drugs at a significantly diminished concentration relative to other methods like urine or oral fluid, underscoring the complexity of performing hair drug testing.

Positive screening confirmations utilize GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before needed confirmations. The complete laboratory workflow from Accessioning through Confirmation aligns with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests identify usage up to 90 days, beyond the shorter detection span of urine tests.
• Challenging to manipulate: The difficulty of cheating a hair drug test enhances result accuracy.
• Historical usage insight: It uncovers a timeline of drug use beyond recent consumption.

Limitations:

• Lacks recent usage detection: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests often incur greater costs than alternative testing methods.
• Result variability: Variations like hair color and individual growth rates can influence metabolite concentrations.

Note: Often termed "hair follicle tests", the procedure analyzes the hair itself, not the scalp’s hair follicle.

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.
