Hair Follicle Drug Testing - Readsville, MO

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the developing strand. By collecting hair near the scalp, it can reveal up to an approximately 3-month window for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and can be shipped with ease.

A 1.5-inch portion consisting of around 200 strands (akin to the girth of a #2 pencil) next to the scalp yields 100mg, an ideal sample size for screening and confirmation purposes. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the specimen is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent volume of body hair can be taken. In the context of head hair, it denotes scalp hair exclusively. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory’s framework. This comprises verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not supported by an electronic chain of custody system.

Screening entails an initial expedited assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug use in the majority of samples, a positive finding requires confirmation to be admissible in court. Any preliminarily positive samples in Screening necessitate secondary confirmation.

Should a sample be preliminarily positive during the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. At this stage, drugs are isolated from hair at markedly lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug Screening the most complex methodology to execute.

Confirmation of any positive result in Screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples are cleansed prior to confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to urine tests, which have a shorter detection timeline.
• Hard to falsify: Cheating a hair drug test is highly challenging, leading to more precise results.
• Offers historical insight: It furnishes a usage pattern over time, rather than merely recent consumption.

Limitations:

• Inability to detect recent usage: Detection of drugs in hair typically requires 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Elements like hair color and individual growth rates can affect drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the examination focuses on the hair strand, not the follicle under 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.
