Hair Follicle Drug Testing - Greenville, NY

What it is, How it works

Regarded as a potent mechanism for identifying drug and alcohol consumption, hair analysis offers an extended historical account by capturing biomarkers within the hair strand's fibers. By obtaining hair close to the scalp, there's a roughly 3-month detection range for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and uncomplicated to transport.

A sample measuring 1.5 inches, approximately 200 hair strands (akin to the thickness of a #2 pencil), closest to the scalp yields 100mg of hair, optimal for both screening and validation. For EtG, additional tests, or those exceeding 10 panels, a specimen of 150mg is preferable. Utilizing a jeweler’s scale for specimen weighing is advised. Should scalp hair be unavailable, an equivalent amount of body hair is acceptable. Head hair pertains exclusively to scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The drug test laboratory procedure encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the preliminary phase wherein a sample is introduced into the laboratory’s system, ensuring it was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data input absent from an electronic chain of custody system.

Screening serves as an initial rapid assessment for substance abuse. Though cost-effective in excluding drug use in most samples, a positive screen must undergo confirmation to be judicially admissible. Presumptive positive samples from Screening require further corroboration.

If Screening indicates a presumptive positive, more hair from the original specimen undergoes preparation for Extraction. Here, drug extraction occurs at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to necessary confirmation. The entire lab sequence from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection timeline: Capable of indicating drug use for up to 90 days, surpassing the shorter timeline of urine tests.
• Resistant to deceit: Hair drug tests are extremely challenging to manipulate, enhancing result accuracy.
• Yields historical insights: It portrays a timeline of drug use patterns over time, beyond immediate consumption.

Constraints:

• Lacks detection of recent consumption: Drugs typically become traceable in hair after 5-7 days.
• Expense: Hair drug testing generally incurs higher costs relative to alternative methods.
• Result variability: Differences such as hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", these assessments evaluate the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Greenville, NY, far surpasses traditional urine tests by offering superior benefits. While both tests detect substance use, hair testing exhibits higher detection accuracy and is less susceptible to tampering. Hair testing's ability to reveal drug use over a more extended period gives it an edge over urine tests, offering a conclusive insight into an individual's history.

Extended Detection Window

The extended detection window is a prime advantage of hair follicle testing in Greenville, NY. Unlike other methods, it uncovers drug use up to 90 days prior. This broad detection period proves invaluable for employers seeking to understand an applicant's substance history, offering a more comprehensive overview beyond immediate past uses.

Tamper-Resistant Testing Method

Reducing possibilities of sample alteration, hair follicle testing in Greenville, NY, stands out for its tamper-resistant nature. This advantage ensures that results remain credible and true to the sample's integrity, giving stakeholders confidence in the reliability of their findings without concerns over potential manipulation.

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.
