Hair Follicle Drug Testing - Randolph Afb, TX

What it is, How it works

Hair analysis has emerged as a powerful means for uncovering drug and alcohol consumption. It provides an extensive historical record of alcohol and drug usage by capturing biomarkers within the strands of growing hair. When sourced close to the scalp, hair samples can offer a detection window extending up to 3 months for alcohol and drugs. The collection process is straightforward, the likelihood of adulteration is low, and shipping is convenient.

A 1.5-inch segment of around 200 hair strands (approximately equivalent to a #2 pencil’s thickness) near the scalp produces 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, or evaluations beyond 10 panels, a sample weighing 150mg is advised. It is recommended to use a jeweler’s scale for accurate specimen measurement. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types of hair (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result can be summarized in four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab's system. It involves verifying that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening entails a preliminary swift check for drugs of abuse. Although a cost-efficient measure to dismiss drug usage in most cases, any positive screening must be corroborated to be legally admissible. Samples with presumptive positive results in Screening require secondary confirmation.

When a sample registers as presumptively positive during Screening, further hair is extracted from the initial sample for Extraction. Here, drugs are extracted at reduced concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug analysis is particularly challenging.

Confirmation is achieved via GC/MS, GC/MS/MS, or LC/MS/MS for any results that are screened positive. All presumptive positive samples undergo washing before confirmation as deemed necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug assessments detect drug consumption for up to 90 days, unlike urine tests that have a shorter detection window.
• Challenge to manipulate: It is exceedingly difficult to counterfeit results in a hair drug assessment, enhancing accuracy.
• Captures historical usage: This testing can display a pattern of drug use over time, beyond recent consumption.

Limitations:

• Inability to detect recent use: A 5-7 day period is generally required before drugs become detectable in hair.
• Expense: Hair drug assessments typically cost more than other drug testing methods.
• Result fluctuations: Hair color and individual growth rates can affect drug metabolite concentrations in hair.

Note: Although occasionally termed as "hair follicle tests", the actual examination assesses the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
