Hair Follicle Drug Testing - Alton, IL

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol usage. Hair captures a long-term record of drugs and alcohol by preserving biomarkers within the strands as they grow. When cut near the scalp, hair can reveal drug and alcohol consumption within a roughly 3-month timeframe. Hair is straightforward to gather, less prone to tampering, and simple to transport.

A sample of 1.5 inches consisting of 200 hair strands (approximating a #2 pencil) nearest to the scalp provides 100mg, which is ideal for both screening and confirmation. For EtG testing, adding more panels beyond 10 panels suggests collecting 150mg. It's advisable to measure the sample with a jeweler’s scale. If scalp hair isn't present, an equivalent amount of body hair can be used. When referencing head hair, we mean scalp hair only. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory process for drug testing results includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab’s workflow, which checks that the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any lacking data not covered by an electronic custody system.

Screening provides an initial basic assessment for drug use. It's a cost-effective strategy to eliminate the use of drugs in most cases, but positive screens must be confirmed for legal relevance. Presumptive positives in Screening necessitate secondary confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the original sample and prepped for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening among the toughest to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening results. All samples presumed positive undergo pre-confirmation washing if necessary. The end-to-end lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug use spanning up to 90 days, unlike the shorter span of urine tests.
• Difficult to deceive: Attempting to deceive a hair drug test is considerably hard, lending to more credible results.
• Reflects historical usage: It reflects drug consumption patterns over time, not just recent usage.

Limitations:

• Cannot spot recent use: Drugs need about 5-7 days post-consumption to register in hair.
• Expense: Hair drug tests usually cost more than alternative testing strategies.
• Result variability: Hair color and individual growth rates can influence drug metabolite levels in hair.

Note: While colloquially termed "hair follicle tests", the test examines the hair strand and not the follicle underneath 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.
