Hair Follicle Drug Testing - Shelbyville, IL

What it is, How it works

Hair assessments have emerged as an effective method for identifying drug and alcohol consumption. The strands act as a timeline by encapsulating biomarkers within the hair's structure. Hair, when collected near the scalp, offers a detection window of up to roughly 3 months for alcohol and substances. It's easy to gather, less prone to tampering, and straightforward to transport.

A 1.5-inch segment comprising around 200 hairs (akin to the width of a #2 pencil) closest to the scalp equates to 100mg, the ideal amount for analysis. For EtG, further assessments, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, an equivalent quantity of body hair may be used. By "head hair," we mean exclusively scalp hair. "Body hair" includes all non-scalp hair types (e.g., facial, underarm).

Process Overview

The procedure for processing a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a specimen within the lab’s infrastructure. It includes ensuring that the sample is properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing supplementary data entry not accounted for by an electronic chain of custody system.

Screening serves as an introductory assessment for substance abuse. While it is a cost-effective approach to eliminate drug use in most samples, a positive result necessitates validation for legal acceptance. Samples that show a presumptive positive result in Screening need verification.

In cases where a Screening stage indicates a presumptive positive, additional hair is retrieved from the original sample for Extraction. Here, substances are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Validation of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The entire lab workflow, from Accessioning to Confirmation, undergoes scrutiny per the CAP (College of American Pathologists) Hair designation and under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing identifies substance use up to 90 days, unlike urine tests with a shorter range.
• Hard to falsify: Cheating a hair test is challenging, enhancing result reliability.
• Provides usage history: Offers usage patterns over time rather than recent consumption.

Limitations:

• Delayed detection: Drugs become noticeable in hair around 5-7 days after usage.
• Expense: Hair drug assessments are typically pricier than other methods.
• Result variation: Elements like hair color and individual hair growth impact metabolite concentration.

Note: While commonly termed as "hair follicle tests," these evaluations analyze the hair shaft, not the scalp's follicle.

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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings.
