Hair Follicle Drug Testing - Mendota, MN

What it is, How it works

Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair accumulates biomarkers within its strands as it grows, offering a comprehensive timeline of substance use. When cut near the scalp, hair can reveal drug and alcohol intake over a span that may reach three months. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.

Acquiring a 1.5-inch section of roughly 200 hairs (comparable to the circumference of a #2 pencil) from the scalp provides about 100 mg, the optimal quantity for both screening and verification. For EtG, additional tests, and/or panels beyond 10, a 150 mg amount is advised. Using a jeweler’s scale for weighing is suggested. If scalp hair isn’t an option, equivalent body hair may be substituted. "Head hair" specifically means scalp hair, while "body hair" includes all other types (such as facial or axillary).

Process Overview

The processing in the lab for drug test results is comprised of four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is first logged into the lab system. This step ensures the sample is properly sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not handled by an electronic chain of custody.

Screening initiates a preliminary check for drug abuse. While Screening is an economical approach for excluding drug consumption in most samples, positive findings necessitate confirmation for legal acceptability. Any samples that screen positive nonetheless require a follow-up verification.

For samples showing positivity in Screening, additional hair is extracted from the original sample for the Extraction phase. Drugs are isolated from hair at far lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most complex technique to execute.

Positive screening outcomes are corroborated using GC/MS, GC/MS/MS, or LC/MS/MS. All potential positives undergo washing prior to confirmation if necessary. A review of the entire process from Accessioning to Confirmation is conducted under 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 register drug use for as long as 90 days, unlike urine tests which have a shorter time frame.
• Hard to manipulate: Hair drug tests are very challenging to falsify, enhancing result reliability.
• Supplies usage history: This method can reveal a timeline of drug use, beyond just current consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug tests are typically costlier than other testing techniques.
• Result variability: Hair characteristics like color and personal growth rate can influence drug metabolite concentrations in hair.

Note: Though often known as "hair follicle tests," this test examines the strand rather than the follicle under 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.
