Hair Follicle Drug Testing - Pine Grove, LA

What it is, How it works

Hair analysis is now regarded as an effective method for uncovering drug and alcohol consumption. Hair retains a historical record of substances, as biomarkers become embedded within the strands as they grow. A sample cut near the scalp can provide insights into a period covering roughly three months for both alcohol and drugs. Its collection is straightforward, tampering is challenging, and shipping is a breeze.

A proper test sample consists of a 1.5-inch snippet of around 200 strands, approximating the width of a #2 pencil, taken nearest to the scalp, providing 100mg of hair, ideal for both screening and verification. For more comprehensive tests, such as for EtG or those exceeding 10 panels, a sample weighing 150mg is recommended. It's advisable to use a jeweler’s scale for weighing. If scalp hair isn't accessible, an equivalent portion of body hair may be used. "Head hair" strictly refers to scalp hair, while "body hair" encompasses all other types, like facial or underarm hair.

Process Overview

There are four key stages in processing a lab drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating a sample into a lab's workflow, ensuring it's securely sealed and sent correctly, linking it to a unique LAN (Laboratory Accessioning Number), and filling in any extra information not captured by the digital custody system.

Screening serves as a preliminary check for substance abuse. It’s a budget-friendly technique for dismissing usage in most samples, but a positive finding here must be confirmed for legal acceptance. Any samples testing positive at this stage will need confirmatory testing.

For specimens anticipating a positive result during Screening, additional hair from the primary sample is required for Extraction. Here, drugs are drawn out from hair at a significantly lower concentration compared to other methods such as urine or saliva tests, hence making hair testing one of the more complex techniques.

Confirmation of positive screenings utilises GC/MS, GC/MS/MS or LC/MS/MS methods. Prior to confirmation, all samples presumed positive undergo washing as necessary. Every step from Accessioning to Confirmation is examined in line with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair tests track drugs used up to 90 days back, while urine tests offer a shorter window.
• Hard to tamper: Manipulating results of a hair drug test poses a significant challenge, enhancing accuracy.
• Chronological usage data: Provides a timeline of substance use, not limited to recent activity.

Limitations:

• Recent usage undetectable: It typically takes 5-7 days post-consumption for drugs to appear in hair.
• Expense: Generally, hair tests cost more than other testing methods.
• Result variability: Factors such as hair pigmentation and growth rates influence the metabolite levels in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the strand rather than the follicle itself.

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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
