Hair Follicle Drug Testing - Oliver, IL

What it is, How it works

Recognized as a potent method, hair testing is valuable for uncovering drug and alcohol consumption. By encasing biomarkers in the fibrous structure of hair strands as they grow, hair offers a comprehensive timeline of substance use. When sampled near the scalp, the hair can reveal a detection timeline for drugs and alcohol of up to three months. It's easy to collect, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches, consisting of about 200 hair strands, approximately the thickness of a #2 pencil, near the scalp will yield 100mg of hair, which is ideal for testing. For EtG, additional screens, and extensive tests surpassing 10 panels, a 150mg specimen is advised. Utilizing a jeweler's scale is recommended for accurate measurement. If scalp hair is unavailable, equivalent body hair can be used. Reference to head hair implies scalp hair only, while body hair includes all other hair varieties (facial, axillary, etc.).

Process Overview

The main stages in processing laboratory results for drug tests include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where samples are processed into the lab's system. This involves ensuring the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and filling out any additional data not covered by an electronic chain of custody system.

Screening is a preliminary examination to detect drug misuse. While this is an economical approach to eliminate drug use in most samples, any positive findings in Screening must be verified to be valid legally. Presumptive positive samples in Screening necessitate a follow-up confirmation.

For samples testing positive during Screening, additional hair is sourced from the initial specimen for Extraction. This stage isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or saliva), which is why hair drug screening is the most challenging technique to execute.

Confirming a positive Screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as required. The full process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with a shorter window.
• Hard to deceive: Cheating a hair drug test is extremely tough, enhancing result accuracy.
• Delivers historical insight: It illustrates drug usage patterns over time, not solely recent consumption.

Limitations:

• Inability to detect recent use: Drugs require roughly 5-7 days to be traceable in hair.
• Expense: Hair drug tests are usually pricier than alternative drug testing techniques.
• Result variations: Drug metabolite levels in hair can vary based on hair color and individual hair growth differences.

Note: Commonly known as "hair follicle tests", these tests actually analyze the hair strand, 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.
