Hair Follicle Drug Testing - Rossiter, PA

What it is, How it works

Hair analysis has emerged as a significant method for uncovering drug and alcohol use. Hair retains biomarkers within its fibers, reflecting long-term usage of substances like alcohol. When clipped near the scalp, it offers a detection timeframe of up to 3 months for alcohol and drugs. Collecting hair is straightforward, hard to tamper, and simple to transport.

An ideal amount for testing is a 1.5-inch lock of around 200 hairs (similar to a #2 pencil), equating to 100mg, perfect for screening and validation. For EtG, extended panels, or tests beyond 10 panels, 150mg is advised. We suggest weighing the hair using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be substituted. In our context, "head hair" refers explicitly to scalp hair, while "body hair" encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory drug test analysis comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is integrated into a laboratory’s system. This process involves ensuring the sample is correctly sealed and transported, assigning it a LAN (Laboratory Accessioning Number), and completing additional data entry if not already in place via an electronic chain of custody.

Screening serves as an initial testing phase to detect drug misuse. Although Screening offers a cost-effective approach to dismiss drug use for many samples, a positive result must be validated for judicial purposes. Any samples showing a preliminary positive in Screening require further confirmation.

Upon a presumptive positive Screening result, more hair is separated from the original sample and readied for Extraction. Here, drug compounds are extracted from hair at lower concentrations compared to other methods (e.g., urine or saliva), making hair drug analysis particularly complex.

Validation of any positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS technology. All preliminarily positive specimens undergo washing before confirmation when necessary. Every stage from Accessioning to Confirmation is rigorously evaluated under the CAP (College of American Pathologists) Hair category and certified to ISO / IEC 17025 standards.

Merits of hair drug analysis:

• Extended detection period: Hair tests can trace drug use for up to 90 days versus a shorter span for urine tests.
• Resistance to manipulation: The difficulty in cheating a hair test enhances result reliability.
• Historical usage insights: It reveals a consumption pattern over time, not restricted to recent usage.

Drawbacks:

• Inability to detect recent intake: Typically, 5-7 days are required before drugs become traceable in hair.
• Expense: Generally, hair tests are costlier than alternative drug testing approaches.
• Result variability: Drug metabolite concentrations can vary due to hair color and individual hair growth differences.

Note: Despite the common phrase "hair follicle tests," the analysis targets the hair strands, not the follicles 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.
