Hair Follicle Drug Testing - Sun Prairie, MT

What it is, How it works

Hair testing stands out as a potent method for detecting drug and alcohol use. Hair captures a comprehensive history of drug intake by embedding biomarkers within the structure of the growing hair strand. When samples are taken close to the scalp, they offer an approximate 3-month window for spotting alcohol and drug presence. The process is straightforward, fairly tamper-resistant, and easy to transport.

A 1.5-inch sample of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp provides 100mg of hair, ideal for both screening and subsequent validation. For EtG, additional testing, and panels exceeding 10, a specimen of 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unattainable, an equivalent quantity of body hair may be collected. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into the laboratory’s system. This phase checks whether the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry that is not provided by an electronic chain of custody.

Screening is a preliminary check for substances of abuse. Although Screening economically helps rule out drug use in most samples, any positive findings require confirmation for legal admissibility. Samples with presumptive positive outcomes in Screening need further verification.

Should a sample show a presumptive positive in Screening, additional hair is retrieved from the original specimen and readied for Extraction. This step involves extracting drugs from the hair at much lower concentrations than in other methods like urine or saliva, emphasizing why hair drug screening poses significant challenges in execution.

Verification of any positive Screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before additional analysis if necessary. The complete laboratory sequence from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days prior, unlike urine tests with a more limited timeframe.
• Hard to manipulate: Attempts to undermine a hair drug test are notably difficult, ensuring more precise results.
• Reveals historical patterns: It provides insights into drug consumption trends over time, instead of just recent use.

Limitations:

• Cannot spot recent drug use: It typically takes around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Variations in results: Hair color and personal differences in hair growth may affect drug metabolite concentrations.

Note: Though often dubbed "hair follicle tests", these tests analyze the hair strand, not the follicle beneath 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.
