Hair Follicle Drug Testing - Templeville, MD

What it is, How it works

Hair testing is increasingly regarded as a significant method for identifying drug and alcohol consumption. It captures biomarkers within the fibers of the developing hair strand, offering a prolonged record of substance use. When sourced near the scalp, hair can indicate drug and alcohol use within an approximate three-month framework. The process of hair collection is straightforward, challenging to manipulate, and simple to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil in width) nearest to the scalp provides 100mg, which is an optimal quantity for testing and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a suggested amount of 150mg is needed. It's advisable to gauge the specimen using a jeweler’s scale. If scalp hair is absent, a comparable amount of body hair may be gathered. The term head hair pertains specifically to scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

There are four primary steps in processing drug test samples in a lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial integration of a sample into the laboratory's framework. This step verifies sample integrity upon sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not facilitated through an electronic chain of custody system.

Screening executes a preliminary review for substances. This method is economical for negating drugs in most samples; however, a preliminary positive necessitates confirmation for legal acceptance. Any specimens indicating a presumptive positive from Screening need a secondary validation.

When a specimen shows a presumptive positive at Screening, additional hair is extracted from the original sample and readied for Extraction. During this phase, the concentration of drugs is retrieved from hair at levels lower than alternative methods, such as urine or saliva, thus rendering hair drug testing as the most intricate methodology.

GC/MS, GC/MS/MS or LC/MS/MS techniques confirm any positive Screening outcomes. Every presumptive positive subset is cleaned before Confirmation as necessary. The full laboratory protocol, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation measures.

Advantages of hair drug testing:

• Lengthy detection timeframe: Hair drug assessments can disclose drug use up to 90 days, whereas urine tests offer a briefer detection period.
• Minimal chances of deception: The complexity of cheating on a hair drug test results in more credible outcomes.
• Historical insight: It unveils a pattern of substance use over time, rather than just indicating recent intake.

Limitations:

• Incapable of spotting recent consumption: Drugs take around 5-7 days to manifest in hair.
• Expense: Hair drug screenings generally incur greater costs than other drug testing techniques.
• Result variability: Elements like hair color and personal hair growth diversity might impact drug metabolite concentrations in the hair.

Note: Although commonly called "hair follicle tests," the examination pertains to the hair itself, excluding the follicle at the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing the benefits of hair follicle tests against traditional urine tests in Templeville, MD, the former outshines in detection accuracy and reliability.

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.
