Hair Follicle Drug Testing - Ligonier, IN

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying substance use. By embedding biomarkers within the developing hair fibers, hair offers a prolonged record of substance consumption. When gathered near the scalp, hair provides roughly a 3-month period for detecting substances. It's straightforward to gather, challenging to tamper with, and convenient for transport.

A 1.5-inch section with approximately 200 hair strands (approximating the size of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for analysis and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale to measure the specimen. Should scalp hair be unavailable, a comparable quantity of body hair may be used. "Head hair" applies solely to scalp hair, whereas "body hair" encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The core stages in processing a drug test result within a lab encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is incorporated into the laboratory’s system, ensuring the sample's seal and correct shipping, assigning a random LAN (Laboratory Accessioning Number), and performing necessary supplementary data entry absent from an electronic chain of custody system.

Screening provides an initial drug abuse assessment. Though economical for mostly ruling out drug presence, any positive findings require confirmation for court admissibility. Screening’s presumptive positives necessitate a secondary validation.

In instances of presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction process. This phase extracts drugs from hair at significantly lower concentrations than methods like urine or oral fluid, establishing hair drug testing as the most challenging technique.

Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The Accessioning to Confirmation process is thoroughly reviewed in accordance with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is exceedingly challenging, enhancing result accuracy.
• Captures usage history: It traces drug consumption patterns over time, not solely recent usage.

Limitations:

• Delayed detection of recent use: It takes around 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug testing is typically pricier than alternate testing methods.
• Result variability: Variables like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: While dubbed "hair follicle tests", the analysis evaluates the hair strand, not the follicle beneath 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.
