Hair Follicle Drug Testing - Monroe, OR

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a long-term record of substances by embedding markers within the strands of hair as it grows. When hair is taken directly from the scalp, it offers an alcohol and drugs detection period of up to around 3 months. Collection is straightforward, it’s relatively hard to tamper with, and shipping is uncomplicated.

A 1.5-inch segment of around 200 hairs (comparable to a #2 pencil width) nearest to the scalp will yield approximately 100mg, which is optimal for both screening and confirmation purposes. For EtG, additional tests, or tests over 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weight is advised. If scalp hair can't be obtained, a similar quantity of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses other types such as facial or axillary hair.

Process Overview

The four fundamental stages in the lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the lab’s system. This process checks that the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody system.

Screening provides an initial rapid test for drugs of abuse. Although Screening offers a cost-efficient approach to exclude drug usage in most samples, confirmed evidence is necessary for legal proceedings. Samples showing presumptive positives in Screening require secondary confirmation.

For samples with presumptive positives at the Screening phase, additional hair is taken from the initial sample for Extraction preparation. Here, drugs are removed from hair at much lower concentrations than in other testing forms (e.g., urine or oral fluid), making hair drug screening the most challenging method to implement.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive undergo washing before confirmation as needed. The full laboratory process, from Accessioning to Confirmation, is reviewed under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing can identify drug usage for as long as 90 days, unlike urine tests with shorter detection spans.
• Challenging to falsify: Hair drug tests are notably hard to cheat, thus yielding more dependable results.
• Historical usage data: Offers insights into drug usage patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs generally become detectable in hair after about 5-7 days.
• Expense: Hair drug testing costs are typically higher compared to other drug testing forms.
• Result variability: Elements such as hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: While often named as "hair follicle tests", the procedure analyzes the hair strand, not the follicle underneath the scalp.

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.
