Hair Follicle Drug Testing - Williamson, AZ

What it is, How it works

The use of hair testing has emerged as an effective means of identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by holding biomarkers within the strands of hair as they grow. When taken near the scalp, hair samples can offer a detection timeframe of up to roughly 90 days for alcohol and other substances. Collection of hair is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch section consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp can yield 100mg of hair, which is the ideal quantity for testing and validation purposes. For EtG, additional markers, and/or screenings beyond 10 panels, a 150mg sample is advisable. We suggest measuring the sample using a jeweler’s scale. Should scalp hair be absent, an equivalent portion of body hair may be utilized. References to head hair specifically denote scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The overarching process for lab handling of a drug test outcome includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially integrated into the lab's framework. This phase entails confirming that the sample was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry that wasn't covered by an electronic chain of custody protocol.

The Screening phase involves a preliminary quick assessment for substances of abuse. While screening is economical for eliminating drug use in the majority of samples, a positive screen requires confirmation for legal admissibility. Any specimens that show a preliminary positive result during Screening need a secondary validation.

When a sample displays a presumptively positive result during the Screening phase, further hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are withdrawn from hair at a significantly lower concentration in contrast to other methods (e.g., urine or oral fluid), explaining why hair drug analysis is among the most challenging methods to execute.

Validation of any positive results from screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive outcome are cleansed before validation as required. The entirety of the lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use spanning up to 90 days, as opposed to urinary tests with a shorter detection span.
• Hard to manipulate: A hair drug test is challenging to deceive, rendering the findings more precise.
• Historical use patterns: It can demonstrate a timeline of drug usage over durations, not merely recent activity.

Limitations:

• Incapable of recent detection: Drugs require roughly 5-7 days before becoming traceable in hair.
• Expense: Hair drug evaluations typically cost more than other drug testing techniques.
• Result variability: Variables like hair color and individual growth differences can alter metabolite concentrations in the hair.

Note: Despite the common reference to "hair follicle tests," the actual analysis focuses on the hair strand, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Williamson, AZ, hair follicle testing offers distinct advantages over traditional urine tests. Its superior detection accuracy captures drug use history more reliably. Compared to urine tests, which have a limited detection window, hair testing can retrospectively show substance use patterns, assisting in making informed decisions.

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.
