Hair Follicle Drug Testing - Mount Vernon, IL

What it is, How it works

Recognized for its effectiveness, hair testing serves as an advanced method for identifying drug and alcohol consumption. Hair captures a comprehensive record of drug and alcohol use by ensnaring biomarkers within its growing strands. When obtained near the scalp, hair can provide an approximate 3-month detection timeline for alcohol and drugs. Hair collection is straightforward, moderately tamper-resistant, and easily transportable.

Acquiring a 1.5-inch section of around 200 hair strands (roughly equivalent to a #2 pencil's thickness) nearest the scalp yields 100mg of hair, the optimal sample size for both screening and confirming. For EtG, extended tests, and/or those exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale for precise weighing. Should scalp hair be inaccessible, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test involves four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning integrates a sample into a laboratory system initially. This step ensures that the sample is correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and inputs any supplementary data not captured electronically in the chain of custody.

Screening provides a preliminary rapid assessment for potential drug abuse. Although Screening is an economical approach to eliminate drug use in many samples, a positive outcome requires confirmation to be valid in legal contexts. All samples that yield a positive presumption in Screening necessitate subsequent confirmation.

For any sample flagged as presumptively positive during Screening, additional hair is gathered from the initial sample for Extraction. This phase isolates drugs from hair at substantially lower concentrations than alternative methods (e.g., urine or oral fluid), rendering hair drug screening a notably challenging methodology.

Confirmation for any positive result post-Screening is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation, as required. The entire laboratory process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) guidelines and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a more limited detection span.
• Resistant to cheating: Cheating a hair drug test is very challenging, leading to more reliable results.
• Tracks historical usage: Offers an overview of drug habits over time, beyond just recent consumption.

Limitations:

• Incapable of identifying recent usage: Drugs require about 5-7 days to be traceable in hair.
• Expense: Hair drug tests are typically pricier compared to other drug testing techniques.
• Result variations: Elements such as hair color and individual hair growth rates can influence the drug metabolite concentration in hair.

Clarification: Although frequently called "hair follicle tests," the analysis focuses on the hair strand instead of 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.
