Hair Follicle Drug Testing - Clemons, IA

What it is, How it works

Hair testing is recognized as a highly effective method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of a growing hair strand, hair offers an extended history of substance use. When obtained near the scalp, it can reveal alcohol and drug usage over an approximate 3-month period. Hair sample collection is straightforward, is somewhat resistant to tampering, and can be easily transported.

A 1.5-inch section containing around 200 hair strands (roughly equivalent to the thickness of a #2 pencil) offers 100mg of hair, which is ideal for both screening and confirmation processes. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. It's best to use a jeweler's scale for weighing the specimen. If hair from the scalp isn't available, a similar amount of body hair can be collected. When referring to head hair, we specifically mean scalp hair. Conversely, body hair includes all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory drug test processing involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples are initially processed into the lab's system, verifying proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and executing any necessary data entry omitted by an electronic chain of custody system.

Screening consists of a preliminary examination for drug abuse. Although it's a cost-efficient method to eliminate most drug usage cases, confirmed results are required for legal scenarios. Thus, any samples preliminarily positive in Screening mandate secondary confirmation.

For samples testing positive initially in Screening, additional hair is extracted from the primary specimen for Extraction. Here, drugs are drawn from the hair at notably lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most formidable technique.

Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Preceding Confirmation, all presumptive positive samples are appropriately washed. The complete lab process, from Accessioning to Confirmation, is assessed per the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use up to 90 days, unlike urine evaluations with shorter detection periods.
• Hard to falsify: Tampering with a hair drug test is challenging, enhancing result accuracy.
• Chronological data provided: This method demonstrates a drug use pattern over time instead of mere recent consumption.

Drawbacks:

• Incapable of detecting recent use: Drugs require about 5-7 days to manifest in hair.
• Expense: Typically, hair drug tests incur higher costs compared to other testing techniques.
• Result variability: Variables like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Though frequently termed as "hair follicle tests," the analysis is performed on 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. 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.
