Hair Follicle Drug Testing - Dalton, GA

What it is, How it works

Hair analysis is increasingly recognized as a strong method for uncovering drug and alcohol consumption. It captures long-term substance use data by embedding biomarkers within the hair strand's fibers as it grows. When hair is harvested near the scalp, it can reveal information about drug and alcohol consumption for up to about 90 days. Hair has the advantages of being easy to collect, somewhat resistant to tampering, and straightforward to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp provides 100mg, the perfect amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. Using a jeweler’s scale to weigh the sample is advised. In cases where scalp hair isn't present, a similar quantity of body hair can be obtained. Note that head hair strictly refers to scalp hair alone. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results is primarily comprised of four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into the lab's system, ensuring the sample was sealed and shipped correctly, shouldering a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not managed by an electronic chain of custody system.

Screening acts as a preliminary inspection for drugs of abuse. While it is an economical approach for excluding drug usage in the majority of samples, a positive screen needs verification to be court-valid. Presumptively positive Screening samples necessitate subsequent confirmation.

Should a sample test positive at the Screening step, additional hair is extracted from the original specimen in preparation for Extraction. During Extraction, substances are extracted from hair at a reduced concentration versus other practices (e.g., urine or oral fluid), making hair drug screening a highly challenging practice.

Confirmation of any initial positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if needed. The entire laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair recognition and the ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair assessments can determine drug use up to 90 days, significantly longer than urine tests.
• Challenge to deceive: The difficulty in circumventing a hair drug test ensures greater result accuracy.
• Historical consumption patterns: It reveals a history of drug use over time, rather than simply recent use.

Limitations:

• Recent usage detection: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair assessments tend to cost more compared to other drug testing techniques.
• Result inconsistency: Hair drug metabolite levels can vary due to individual hair growth and color differences.

Note: Although commonly known as "hair follicle tests", these analyses focus on the hair strand above the scalp rather than the follicle itself.

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.
