Hair Follicle Drug Testing - Sobieski, MN

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged account of substance use by locking biomarkers within the hair strand fibers. When gathered near the scalp, it yields roughly a 3-month timeframe for detecting alcohol and drugs. Collection is straightforward, alteration is somewhat challenging, and shipping is uncomplicated.

A 1.5-inch segment consisting of around 200 hair strands (similar to the girth of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or beyond 10 panels, 150mg of the sample is suggested. It’s advisable to weigh the sample with a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair is permissible for collection. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses any other hair type (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of introducing the sample into the laboratory’s system. This entails ensuring the sample was sealed and transported appropriately, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any extra data entry necessities absent from an electronic chain of custody system.

Screening administers an initial rapid assessment for drugs of abuse. While it's economical for eliminating drug use in most samples, a positive result in screening needs confirmation to stand in court. Any samples appearing presumptively positive in Screening necessitate further confirmation.

In instances where a sample indicates a presumptive positive during Screening, additional hair is taken from the original sample for Extraction. At this phase, drugs are extracted from hair at notably lower concentrations compared to other approaches (like urine or oral fluid), underscoring the complexity of performing hair drug screenings.

Confirmation of any positive screening results is accomplished utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumed positivity are washed before confirmation if required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use for up to 90 days, unlike urine tests with a shorter window.
• Challenging to deceive: Cheating a hair drug test is highly difficult, enhancing result accuracy.
• Historical insight: It outlines a pattern of drug consumption over time, beyond immediate use.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to register in hair.
• Expense: Hair drug tests tend to be costlier compared to alternative testing methodologies.
• Result variability: Factors, including hair color and individual hair growth variations, can influence the concentration of drug metabolites in hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand rather than the scalp’s hair follicle.

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.
