Hair Follicle Drug Testing - Carlin, NV

What it is, How it works

Hair analysis has emerged as an effective approach for identifying substance and alcohol use. Hair offers a comprehensive timeline of substance exposure by encapsulating biomarkers within its growing strands. When collected near the scalp, hair can reveal up to a 90-day detection window for alcohol and other drugs. Hair is easy to obtain, somewhat resistant to tampering, and simple to transport.

An ideal sample for screening and verification consists of a 1.5-inch section of around 200 hair strands (approximately the width of a #2 pencil) taken nearest to the scalp, providing 100mg of hair. For EtG, extra tests, and/or assessments beyond 10 panels, a 150mg specimen is suggested. We advise weighing the sample on a jeweler's scale. If scalp hair is unavailable, a similar quantity of body hair can be gathered. Reference to head hair indicates only scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The four essential phases in the laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's system. This process involves confirming that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not provided by an electronic chain of custody system.

Screening is a preliminary analysis for substances of abuse. Although Screening is a cost-efficient method for excluding drug use in most samples, a positive screen requires confirmation to be valid in court. Any samples that test presumptively positive in Screening necessitate further confirmation.

If a sample tests positive initially in the Screening phase, additional hair is extracted from the original specimen for Extraction preparation. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), delineating why hair drug screening is the most intricate methodology to execute.

Any positive screening outcome undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation as required. The entire laboratory workflow, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection duration: Hair drug tests can discern drug use for up to 90 days, whereas urine tests have a briefer detection period.
• Hard to falsify: It is challenging to manipulate a hair drug test, which enhances result accuracy.
• Yields historical data: It can reveal a drug use pattern over time, not limited to recent consumption.

Limitations:

• Inability to identify recent usage: It takes approximately 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing techniques.
• Result variability: Elements such as hair color and individual growth variations can influence drug metabolite concentrations in hair.

Note: Often labeled as "hair follicle tests," the analysis focuses on hair strands rather than 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.
