Hair Follicle Drug Testing - Thomasboro, IL

What it is, How it works

Hair analysis has emerged as an influential method for identifying drug and alcohol consumption. The fibers of the growing hair strand encapsulate biomarkers, rendering a prolonged history of substance use. When the hair is cut near the scalp, it can reveal up to around a 90-day detection period for substances. Hair is easy to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (resembling the thickness of a #2 pencil) nearest the scalp yields 100mg, which is the preferred sample for both screening and confirmation. For EtG tests, additional screenings, or tests beyond 10 panels, 150mg of hair is advisable. It's suggested to use a jeweler’s scale for measuring the sample. If scalp hair is inaccessible, a comparable quantity of body hair may be gathered. When addressing head hair, it specifically pertains to scalp hair. Body hair includes all alternative hair forms (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab-based processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a laboratory's database. This procedure ensures the sample's seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent in an electronic chain of custody framework.

Screening performs a preliminary rapid assessment for substance abuse indicators. Although cost-efficient, a positive screen warrants confirmation for legal admissibility. Samples yielding presumptive positives during Screening necessitate further confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. This step involves isolating drugs from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most intricate methodologies to execute.

Confirmation of positive results from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed before confirmation if required. The entire lab procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screening can identify drug consumption for as long as 3 months, unlike urine tests that offer a shorter detection period.
• Increased difficulty for manipulation: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Presents historical patterns: Offers an overview of substance use trends over time, not just recent instances.

Limitations:

• Inability to detect recent usage: Drugs only become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug screenings generally incur higher costs compared to other drug testing approaches.
• Result discrepancies: Variables like hair color and individual hair growth differences can affect drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the analysis examines the hair strand itself rather than 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.
