Hair Follicle Drug Testing - Corinth, MS

What it is, How it works

Hair testing has emerged as an effective approach for identifying drug and alcohol consumption. Hair retains long-term evidence of alcohol and drug intake by embedding biomarkers within the strands as they grow. When harvested near the scalp, hair can indicate alcohol and drug exposure over roughly a three-month period. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.

A 1.5-inch segment consisting of about 200 hair strands (resembling a #2 pencil's girth) close to the scalp yields 100mg of hair, which is the preferred sample size for analysis and validation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. We suggest utilizing a jeweler’s scale for assessing the specimen weight. If scalp hair is inaccessible, body hair of equivalent volume can be utilized. We specify scalp hair when mentioning head hair, while body hair covers other types (such as facial or axillary).

Process Overview

The primary phases in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially integrating a sample into a lab’s system. This step covers validating the sample's seal and shipment, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data entry outside of an electronic chain of custody system.

Screening acts as a preliminary rapid evaluation for common illicit drugs. While it provides a cost-efficient method to exclude drug presence in most samples, a positive result must undergo confirmation to be legally binding. Samples with presumptive positives in Screening require additional confirmation.

For samples with a presumptive positive finding during Screening, further hair is extracted from the original sample for the Extraction stage. In this stage, drugs are isolated from hair at considerably reduced levels compared to other techniques (e.g., urine or oral fluid), making hair drug testing exceedingly challenging.

Confirmation follows any initial positive screening result using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 compliance.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use up to 90 days, outperforming urine tests with shorter detection spans.
• Hard to manipulate: Hair drug tests are challenging to evade, leading to more precise results.
• Delivers retrospective data: It provides a pattern of drug consumption over time, rather than just recent usage.

Limitations:

• Incapable of identifying recent use: It requires 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing often incurs higher costs compared to alternative methods.
• Inconsistent outcomes: Differences such as hair color and personal hair growth rates can impact drug metabolite levels in the hair.

Note: Although commonly termed as "hair follicle tests", this examination evaluates the hair strand rather than 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.
