Hair Follicle Drug Testing - Harney, OR

What it is, How it works

Hair analysis is recognized as an influential method for identifying drug and alcohol consumption. Hair retains a historical record of substances by embedding biomarkers within its fibers. When collected near the scalp, hair offers a detection window of approximately three months for alcohol and drugs. Hair samples are straightforward to gather, relatively tamper-resistant, and simple to transport.

A 1.5-inch portion of about 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, optimal for tests and verification. For EtG, extra tests, and panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale to measure the specimen is recommended. If head hair is lacking, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The drug testing procedure in the lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into the laboratory system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any data gaps not covered by an electronic chain of custody system.

Screening performs a preliminary evaluation for substance abuse. Although screening is a cost-efficient technique to exclude drug use for most samples, any positive results must undergo confirmation for legal acceptance. Samples that preliminarily show positivity in screening require further verification.

Should a sample be tentatively positive during Screening, additional hair from the original collection is utilized for Extraction. This phase extracts drugs from the hair at lower concentrations compared to other samples (e.g., urine or oral fluid), making hair drug testing the most intricate method to execute.

Positive screening findings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicated as positive are cleaned as part of the confirmation. The laboratory workflow from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair classification and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair substance tests can identify drug usage for up to 90 days, beyond the shorter window of urine tests.
• Reduced likelihood of tampering: It is challenging to manipulate a hair drug test, leading to more reliable outcomes.
• Chronological information: Provides insight into drug habits over time, capturing more than just recent consumption.

Limitations:

• Inability to spot recent consumption: Drugs become detectable in hair about 5-7 days after use.
• Expense: Hair drug tests typically have higher costs than other testing methods.
• Result variability: Factors like hair color and individual hair growth traits can impact drug metabolite levels within hair.

Note: "Hair follicle tests" commonly refer to this type of exam; however, it 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.
