Hair Follicle Drug Testing - Peoria, IL

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains evidence of these substances in its fibers, providing a long-term record. When collected near the scalp, hair can offer an approximate 3-month detection period for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of around 200 hairs (comparable to a #2 pencil) near the scalp yields 100mg, an optimal sample for screening. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is advisable. We suggest using a jeweler’s scale for precision. If scalp hair is unavailable, a corresponding amount of body hair may be used. References to head hair pertain solely to scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug sample entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial step of integrating a sample into a lab's system. This stage includes ensuring the sample was correctly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and performing any pending data entry absent in an electronic chain of custody system.

Screening provides an initial, rapid assessment for drug presence. Although cost-effective for negating drug usage across most samples, a positive result must be verified for courtroom admissibility. Samples indicating a preliminary positive outcome require further confirmation.

If Screening indicates potential drug presence, more hair is drawn from the initial sample and readied for Extraction. This stage involves isolating drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening particularly complex.

Positive screening outcomes undergo confirmation through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, positive samples are cleansed as necessary. The comprehensive lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair tests identify drug usage for up to 90 days, surpassing the shorter windows of urine tests.
• Resistance to falsification: The difficulty in altering a hair test ensures more precise results.
• Provides long-term data: It reveals drug usage trends over time, rather than recent incidences alone.

Limitations:

• Inability to detect recent use: Detecting drugs in hair typically requires 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to alternate methods.
• Result variability: Factors such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests", these analyses actually examine the hair strands, not the follicles 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.
