Hair Follicle Drug Testing - Benton, IL

What it is, How it works

Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of hair as it grows. When gathered near the scalp, it provides a detection timeframe of up to 3 months for alcohol and other substances. Collecting hair is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch sample from around 200 hair strands (roughly the diameter of a #2 pencil) close to the scalp yields 100mg of hair, which is the optimal amount for both screening and verification processes. For EtG, additional tests, and/or testing more than 10 panels, it is advisable to use 150mg of the sample. Using a jeweler's scale for weighing the specimen is suggested. If scalp hair isn't available, a similar quantity of body hair can be utilized. References to head hair specifically mean scalp hair. Body hair pertains to other types (such as facial, axillary, etc.).

Process Overview

The primary stages involved in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a sample within a lab’s system. This task includes confirming the sample was correctly sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and supplementing any further data entry absent from an electronic chain of custody system.

Screening involves an initial cursory assessment for drug abuse. This step is a cost-efficient method to exclude drug use in most samples, but any positive indication requires verification to hold up in legal settings. Samples that show a presumptive positive result in Screening need subsequent confirmation.

If a presumptive positive is noted in the Screening step, more hair is taken from the initial sample and readied for Extraction. During this step, drugs are obtained from hair in much smaller concentrations than alternative methods (urine or oral fluid, for example), making hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo a wash prior to confirmation if necessary. The complete lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug consumption for up to 90 days, whereas urine testing has a more limited detection range.
• Challenging to manipulate: It is extremely challenging to alter a hair drug test, thus ensuring greater accuracy in results.
• Offers historical insights: It highlights drug usage patterns over time, not solely recent usage.

Limitations:

• Not effective for immediate use detection: It typically takes 5-7 days for substances to become detectable in hair.
• Expense: Generally, hair drug testing is pricier than alternate drug testing methods.
• Outcome variation: Elements like hair color and individual hair growth differences can impact the drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", the analysis actually involves the hair strand and not the follicle below 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.
