Hair Follicle Drug Testing - Canton, NC

What it is, How it works

Hair testing has become recognized as an effective means for uncovering drug and alcohol usage. Hair strands retain historical data of alcohol and drugs by embedding biomarkers within the strand fibers. When collected proximal to the scalp, hair can yield approximately a 3-month detection period for drugs and alcohol. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (equivalent to the diameter of a #2 pencil) near the scalp provides 100mg, the optimal quantity for screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, an equivalent amount of bodily hair may be used. References to head hair apply solely to scalp hair. Body hair encompasses all other hair variants (facial, axillary, etc.).

Process Overview

The principal steps in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the preliminary integration of a sample into the laboratory framework. This step ensures the sample was rightly sealed and dispatched, assigns a randomly generated LAN (Laboratory Accessioning Number), and completes additional data entry absent in an electronic chain of custody system.

Screening executes an initial rapid evaluation for drug abuse. Despite being an economical method for excluding drug use in most samples, a positive result from Screening necessitates confirmation to be legally admissible. Samples presumed positive in Screening must receive secondary validation.

Should a Screening result indicate a presumptive positive, further hair from the initial sample is utilized for Extraction. This phase extracts drugs from hair at markedly lower concentrations compared to alternate methods (e.g., urine or oral fluid), rendering hair drug screening particularly challenging.

Positive results from screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Necessary presumptive positive samples undergo washing prior to confirmation. The complete laboratory path from Accessioning to Confirmation is scrutinized both under CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can indicate drug consumption for up to 90 days, while urine tests have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is notably difficult, thereby enhancing result accuracy.
• Delivers historical insight: It offers a timeline of drug usage over time, beyond recent consumption.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to become detectable within hair.
• Expense: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variation: Influences like hair color and growth rate may alter drug metabolite concentrations in hair.

Note: Often termed as "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Canton, NC, hair follicle testing proves superior due to its enhanced detection accuracy and reliability. Unlike urine tests, hair tests offer a broader detection window, capturing months of substance history.

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.
