Hair Follicle Drug Testing - Terlingua, TX

What it is, How it works

Hair testing is now regarded as a potent approach for recognizing drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the growing hair. Gathering hair close to the scalp offers nearly a 3-month timeframe for drug and alcohol detection. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch strand sample containing about 200 hairs (around the dimension of a #2 pencil) nearest the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, additional tests, or assessments beyond 10 panels, a 150mg specimen is advised. It's recommended to weigh the sample using a jeweler’s scale. If hair on the scalp isn't present, a corresponding amount of body hair can be gathered. When discussing head hair, it refers solely to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The four core phases in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entering of a sample into a lab’s system. This entails ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not offered by an electronic chain of custody system.

Screening comprises an initial brief inspection for drugs of abuse. Although Screening is a cost-efficient method to exclude drug consumption in most samples, a positive screen requires confirmation to be valid in court. Any samples that test presumptively positive in Screening necessitate secondary confirmation.

When a sample tests presumptively positive during the Screening phase, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are withdrawn from hair at lower concentrations than in other techniques (e.g., urine or oral fluid), making hair drug screening a challenging procedure to execute.

Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is reassessed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can recognize drug usage for up to 90 days, whereas urine tests have a briefer detection window.
• Hard to manipulate: Manipulating a hair drug test is extremely difficult, resulting in more precise outcomes.
• Yields historical insight: It can depict a trend of drug use over time, rather than just recent activity.

Limitations:

• Incapable of detecting recent use: It takes roughly 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug tests are typically pricier compared to other drug testing techniques.
• Result variations: Elements like hair color and individual differences in hair growth can influence the levels of drug metabolites in hair.

Note: Often identified as "hair follicle tests", the evaluation focuses on the hair strand and 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. 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.
