Hair Follicle Drug Testing - Monmouth, IL

What it is, How it works

Analyzing hair has become recognized as an effective method for identifying alcohol and drug consumption. Hair captures a long-term record of substances by embedding biomarkers within the strands as they grow. When taken near the scalp, it offers a detection range of up to roughly three months for alcohol and drugs. The procedure of collecting hair is straightforward, relatively tamper-proof, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 hairs (similar in thickness to a #2 pencil) nearest to the scalp, provides 100mg, which is optimal for both initial tests and confirmatory analysis. For EtG, additional assays, and/or tests exceeding 10 panels, a recommendation of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't present, an equivalent quantity of body hair can be collected. The term "head hair" strictly refers to scalp hair. Body hair comprises all other hair forms (like facial and axillary).

Process Overview

In a laboratory setting, four core steps form the drug testing process: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary phase where a sample is integrated into the laboratory's system. This stage involves ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not handled by an electronic chain of custody.

Screening carries out a preliminary evaluation for substances of abuse. While Screening offers a budget-friendly option for excluding drug presence in most cases, any positive findings from this stage need to be confirmed for legal acceptability. Presumptively positive samples in Screening necessitate further confirmation.

For samples that are presumptively positive during Screening, additional hair is extracted from the original sample and set up for Extraction. Here, drugs are separated from the hair at a lower concentration compared to other methods (such as urine or oral fluid), explaining why hair drug analysis is among the most challenging processes.

Confirmation of positive Screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all preliminary positive samples undergo a washing step as needed. The complete laboratory procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption for up to 90 days, unlike urine tests with a shorter detection scope.
• High integrity: Cheating on a hair drug test is exceedingly difficult, thus enhancing result reliability.
• Historical record: It reflects drug usage patterns over time, not merely recent use.

Limitations:

• Lacks immediacy: It takes roughly 5-7 days for drugs to appear detectable in hair.
• Expense: Hair drug tests usually incur higher costs relative to alternative drug testing methods.
• Result variability: Differences in hair attributes like color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Although commonly referred to as "hair follicle tests", the exam actually assesses the hair shaft rather than the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing provides distinct advantages over urine tests, especially for those needing drug testing in Monmouth, IL. The detection window is substantially longer, allowing for accurate screenings over an extended period. This capability results in a superior detection accuracy, ensuring employers and other stakeholders gain a reliable assessment compared to traditional methods.

Extended Detection Window

The extended detection window of hair follicle testing, up to 90 days, offers an in-depth view of an individual's substance use history. By capturing a wider timeframe, employers can gain insights into long-term behavior, ensuring better decision-making for maintaining company policies on substance use.

Tamper-Resistant Testing Method

In Monmouth, IL, hair follicle testing asserts itself as a tamper-resistant method, largely eliminating the risk of sample manipulation. Unlike other methods, this testing process ensures sample integrity, helping stakeholders trust the outcomes and make informed decisions based on untampered evidence.

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.
