Hair Follicle Drug Testing - Ashton, MD

What it is, How it works

Hair analysis is now recognized as a robust method for identifying drug and alcohol usage. Hair traps the biomarkers within the strands, offering a comprehensive history of substance intake. Hair collected near the scalp can reveal drug and alcohol use for up to three months. It is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches with approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair—the optimal amount for initial and confirmatory analysis. For EtG, additional tests, or panels beyond 10, 150mg of hair is suggested. Using a jeweler's scale to weigh the sample is advisable. Should scalp hair be inaccessible, a similar mass of body hair can be utilized. We use "head hair" to denote scalp hair specifically, while "body hair" encompasses any other type (such as facial or axillary).

Process Overview

The laboratory drug testing process includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is logged into the lab's system. This step ensures the sample was properly sealed and sent, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from the electronic chain of custody.

Screening is the preliminary check for substances of abuse. Although Screening efficiently and economically rules out drug use in most samples, a positive result requires further confirmation for legal validity. Samples that test positively during Screening must undergo confirmatory testing.

When a sample tests positive in Screening, more hair is extracted from the original specimen for the Extraction phase. In this step, drugs are isolated from hair at a lower concentration compared to other methods like urine or oral fluids, accounting for the complexity of hair drug analysis.

Confirmation of positive Screening results is carried out through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to Confirmation, all presumptive positive samples are washed if necessary. The entire lab process, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and complies with ISO/IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine tests that offer a shorter span.
• Hard to deceive: Cheating in hair drug tests is highly unlikely, increasing the credibility of the results.
• Offers historical insight: It illustrates drug usage patterns over time, not just recent consumption.

Challenges:

• Cannot show recent usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing options.
• Result variability: Elements such as hair color and personal hair growth differences may impact drug metabolite levels.

Note: While commonly termed "hair follicle tests," these tests actually evaluate the hair strand itself, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing excels over urine testing in Ashton, MD, due to superior detection periods and reliability. While a urine test identifies recent use, hair testing extends the window up to 90 days, making it advantageous in providing a broader perspective on substance use patterns.

Extended Detection Window

In Ashton, MD, hair follicle testing offers an extended detection window up to 90 days, surpassing the capabilities of other methods. This comprehensive timeframe allows employers to better assess an individual's substance use history, facilitating informed decision-making.

Tamper-Resistant Testing Method

Hair follicle testing in Ashton, MD, significantly diminishes the chance of tampering with test samples. Unlike other testing methods, altering hair samples is nearly impossible, ensuring dependable results that reflect true behavior, providing greater confidence in the testing process.

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.
