Hair Follicle Drug Testing - Echo, LA

What it is, How it works

Evaluating substance use through hair analysis is recognized as a formidable method for identifying drug and alcohol consumption. Hair captures long-term traces of substances by embedding biomarkers within the strands during growth. When taken from a location near the roots, hair can indicate drug or alcohol use over an estimated three-month period. Hair sampling is straightforward to gather, relatively hard to falsify, and simple to dispatch.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil) in proximity to the scalp yields 100mg of hair, marking it as the preferred amount for both screening and validation. For EtG, add-on tests, or screenings exceeding 10 panels, a sample of 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. The term head hair refers specifically to scalp hair exclusively. In contrast, body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for determining a drug test outcome comprises four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the inaugural step of introducing a specimen into the lab's framework. It ensures the sample was securely sealed and correctly sent, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional information entry beyond what is available from an electronic control system.

Screening carries out a preliminary rapid analysis for drugs of abuse. Although it is an economical approach to dismiss drug consumption in most cases, a positive screening must be validated to be legally credible. Samples that presumptively test positive during Screening necessitate secondary verification.

Upon a presumptive positive result during Screening, more hair is extracted from the original sample and gets ready for Extraction. Here, substances are removed from hair at significantly reduced concentrations compared to urine or oral fluid, making hair analysis the most challenging methodology to execute.

Validation of any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before necessary confirmation. The full lab protocol from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair endorsement and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection span: Hair drug evaluations reveal substance use up to 90 days, whereas urine tests offer a briefer detection time frame.
• Cheat-proof: Manipulating hair drug test outcomes is exceedingly hard, enhancing accuracy.
• Yoields historical insights: This test displays drug usage trends over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent usage: It takes roughly 5-7 days before drugs are traceable in hair.
• Price: Hair drug examinations tend to be pricier relative to alternative drug testing methods.
• Results variation: Aspects like hair pigmentation and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Commonly dubbed as "hair follicle tests", this test scrutinizes the strand and 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.
