Hair Follicle Drug Testing - Leon, IA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of substances by encasing biomarkers within its growing strands. When obtained close to the scalp, hair offers about a three-month period for detecting alcohol and other substances. Hair is effortless to collect, relatively resistant to tampering, and simple to transport.

A 1.5-inch section of approximately 200 hair strands (similar to the width of a #2 pencil) near the scalp provides 100mg, the ideal quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. We recommend utilizing a jeweler’s scale for weighing. Should scalp hair be unavailable, the same weight of body hair can be used. By head hair, we imply only scalp hair; body hair pertains to all other types (such as facial and axillary hair).

Process Overview

The lab processing steps for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is first entered into the lab system. This step ensures the sample is securely sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.

Screening conducts an initial assessment for drug presence. Although cost-efficient for eliminating drug usage in most cases, any positive screen must be validated for legal proceedings. Any samples indicating a presumptive positive in Screening require further confirmation.

If Screening suggests a positive result, additional hair is retrieved from the original sample for Extraction. During Extraction, drugs are separated from hair at a lower concentration level, making hair drug testing more challenging than other methods (such as urine or oral fluid testing).

Confirmation of any positive screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples with presumptive positive findings are cleansed before confirmation as needed. The complete lab procedure from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection span: Hair tests can identify drug use up to 90 days, unlike urine tests which are limited to shorter durations.
• Hard to manipulate: The accuracy of hair drug tests is enhanced by the difficulty in altering results.
• Chronological usage data: It shows drug use patterns over time, not just recent usage.

Limitations:

• Incapability to detect recent usage: It requires approximately 5-7 days for substances to appear in hair.
• Expense: Hair testing often incurs higher costs than other methods.
• Result disparities: Variables like hair color and personal growth rates can influence drug metabolite levels in hair.

Note: While commonly known as "hair follicle tests", the procedure examines the hair strand rather than the follicle below 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.
