Hair Follicle Drug Testing - Leroy, WI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands provide a prolonged timeline of alcohol and drug intake by embedding biomarkers within the hair's developing strands. When gathered near the scalp, hair may reflect up to a 3-month period of detection for alcohol and drugs. Hair collection is straightforward, challenging to alter, and easily transportable.

A sample of 200 hair strands, approximately 1.5 inches long (similar in size to a #2 pencil), nearest to the scalp will yield 100mg of hair, suitable for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advised. Use a jeweler’s scale to weigh the sample. If scalp hair is not accessible, an equivalent quantity of body hair can be used. When mentioning head hair, we refer solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug test laboratory process encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing within a laboratory’s system, including verifying proper sample sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional entries required beyond those in an electronic chain of custody system.

Screening provides a preliminary rapid check for substance abuse. Though cost-efficient for eliminating drug usage in most samples, a positive result in Screening must be confirmed to stand in legal settings. Presumptive positive results in Screening mandate additional confirmation.

Should a sample test as presumptively positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction stage. This stage involves extracting drugs from hair at substantially lower concentrations in comparison to other methods (e.g., urine or oral fluid), making hair drug screening a particularly challenging method to execute.

Confirmed positive results from screening undergo further analysis through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are washed before confirmation if necessary. Each step from Accessioning to Confirmation is reviewed in accordance with both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection time: Hair drug testing can identify drug usage for up to 90 days, unlike urine tests, which feature a more limited timeframe of detection.
• Challenging to tamper with: The potential to deceive a hair drug test is minimal, thus ensuring more reliable results.
• History of usage: It reveals a pattern of drug consumption over an extended period, not limited to recent intake.

Limitations:

• Cannot measure recent consumption: It generally takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Variability in outcomes: Results can be influenced by hair color and individual differences in hair growth, impacting metabolite concentrations in hair.

Note: Commonly misnomered as "hair follicle tests", the analysis actually examines hair strands rather than scalp-embedded follicles.

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.
