Hair Follicle Drug Testing - Merrionette Park, IL

What it is, How it works

Hair analyses have gained recognition as an effective means for identifying substance consumption. Hair fibers capture drug and alcohol indicators, providing a prolonged consumption history. When sampled near the scalp, hair tests can reveal up to a three-month usage period for various substances. Collection is straightforward, tampering is challenging, and transport is convenient.

Gathering a 1.5-inch segment of approximately 200 hair strands near the scalp yields around 100mg, optimal for testing and verification. Additional quantities, such as 150mg, are advised for extensive panels or EtG evaluations. Employ a jeweler’s scale for precise measurement. If scalp hair is unavailable, body hair of equivalent quantity can be utilized. "Head hair" refers solely to scalp locks, whereas "body hair" encompasses all other types (like facial or axillary).

Process Overview

The lab process for drug testing comprises four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase, incorporating the specimen into the lab's system. This step includes ensuring proper sealing and shipment of samples, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from electronic custody chains.

Screening entails an initial drug detection check. Although it's an economical method to exclude drug use in most samples, a positive result must be confirmed for legal acceptance. Presumptive positives in Screening necessitate follow-up confirmation.

A positive indication in Screening leads to additional hair extraction for further analysis. This step involves extracting drugs from hair at much lower levels compared to other methods (like urine or saliva), highlighting the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive Screening results. Samples flagged as presumptive positives undergo washing before confirmation as required. The lab process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 credentials.

Benefits of hair drug testing:

• Extended detection duration: Hair drug tests identify drug use up to 90 days, contrasting with shorter intervals in urine testing.
• Reduced manipulation risk: The accuracy of hair drug tests is bolstered by the difficulty in tampering.
• Patterns over time: It reflects a broader timeline of drug use, beyond just recent activity.

Drawbacks:

• Recent drug use detection is limited: Drugs take roughly 5-7 days to become detectable in hair.
• Higher expenses: Hair drug testing tends to be pricier than other testing methods.
• Result variations: Factors like hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Despite the term "hair follicle tests," the analysis targets the hair strand itself, not 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.

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.
