Hair Follicle Drug Testing - Countryside, IL

What it is, How it works

With the advent of hair testing, the identification of drug and alcohol use has become increasingly effective. Hair strands encapsulate biomarkers within their fibers, offering an extended timeline of alcohol and drug consumption. By procuring hair samples from the region close to the scalp, a detection window of up to three months can be achieved for both alcohol and other substances. The ease of collecting hair samples, paired with their relative resistance to tampering and straightforward shipping, makes hair testing a viable option.

An ideal sample for assessment and validation consists of a 1.5-inch portion of approximately 200 hairs (approximating the girth of a #2 pencil), producing 100mg of material. For EtG enhancements or tests exceeding ten panels, a 150mg specimen is preferred. Utilizing a jewelry scale for precise measurement is advisable. In the absence of scalp hair, a comparable volume of body hair is an acceptable substitute. References to head hair are specific to scalp hair, whereas body hair includes all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for drug testing encompasses four core steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory's system, which involves confirming proper sealing and shipping of the sample, assigning a Laboratory Accessioning Number (LAN) at random, and completing any extra data input absent from an electronic chain of custody.

Screening serves as an initial rapid assessment for substances of abuse. Although Screening offers a cost-efficient method to exclude drug usage in most cases, any positive outcomes require confirmation to be legally valid. Samples that yield presumptive positive results during Screening necessitate further confirmation.

Upon a presumptive positive result at the Screening phase, additional hair is obtained from the original sample for the Extraction process. This stage involves extracting drugs at much lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of conducting hair drug screening.

Confirmation of any positive Screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo a washing process if required before confirmation. The complete laboratory workflow, from Accessioning to Confirmation, is scrutinized under the guidelines of the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug use for up to 90 days, whereas urine tests offer shorter detection spans.
• Enhanced accuracy: The difficulty in cheating a hair drug test contributes to more reliable results.
• Chronological use pattern: This method reveals drug consumption trends over time, not limited to recent intake.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair around 5-7 days post-consumption.
• Higher cost: Hair drug tests tend to be more costly compared to alternative testing approaches.
• Outcome variability: Elements such as natural hair color and individual hair growth rates can influence drug metabolite levels in hair samples.

Note: Although commonly referred to as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the skin.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
