Hair Follicle Drug Testing - Keweenaw Bay, MI

What it is, How it works

Hair analysis has emerged as a strong method for detecting substance and alcohol usage. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers within the structure of the growing hair fiber. When sampled near the scalp, hair offers up to roughly a 90-day detection period for alcohol and drugs. It is easy to gather, difficult to tamper with, and convenient to transport.

Gathering a 1.5-inch segment of around 200 hair strands (roughly the size of a #2 pencil) close to the scalp yields about 100mg of hair, which is the perfect sample size for testing and confirming results. For EtG, extended tests, or panels beyond 10, a sample weighing 150mg is suggested. It is advised to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be taken. In using the term head hair, we refer specifically to scalp hair. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The key stages in laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample upon entering a laboratory's ecosystem. This step confirms that the sample was properly sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry if an electronic chain of custody system is not in use.

Screening offers a swift preliminary review for substances of abuse. Although Screening economically dismisses drug usage in most samples, a positive screening requires validation to hold up in legal cases. Samples returning a presumptive positive from Screening need further confirmation.

If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepared for the Extraction stage. Here, substances are isolated from hair at a significantly lower concentration compared to other methods (like urine or saliva). This attribute makes hair drug testing highly complex.

Any Screening positives undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All provisional positive specimens are cleansed before confirmation if necessary. The entire analytical process from Accessioning to Confirmation is conducted under both CAP (College of American Pathologists) Hair criteria and in adherence to ISO / IEC 17025 certifications.

Advantages of hair drug testing:

• Extended detection range: Hair tests can uncover drug usage for up to 90 days, unlike urine tests, which have a more limited detection timeline.
• Hard to falsify: Cheating a hair drug test is very challenging, enhancing result precision.
• Reveals usage history: It can unveil a pattern of drug usage over months rather than only recent activity.

Limitations:

• Cannot spot recent use: About 5-7 days are necessary for drugs to become noticeable in hair.
• Expense: Hair drug evaluations tend to be more costly than alternative methods.
• Inconsistencies in results: Variabilities like hair hue and personal growth differences can alter metabolite concentration in hair.

Note: Despite often being termed "hair follicle tests," the evaluation targets the hair shaft rather than the follicle beneath the skin.

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.
