Hair Follicle Drug Testing - Troy, AL

What it is, How it works

Hair analysis is now recognized as a significant method to uncover drug and alcohol consumption. Hair provides an extended timeline of alcohol and drug usage by encasing biomarkers within the strands as they grow. When trimmed near the scalp, hair can deliver up to a 3-month insight into alcohol and drug presence. Collecting hair is straightforward, tough to tamper with, and easy to send.

A 1.5-inch portion consisting of roughly 200 hair strands (similar to a #2 pencil’s thickness) closest to the scalp yields 100mg of hair, which is optimal for both screening and validation tests. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of hair is advocated. We suggest utilizing a jeweler’s scale to measure the sample. If scalp hair is not an option, a similar quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The lab processing for a drug test result follows four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the stage where a sample is first logged into the laboratory’s system. This process includes confirming that the sample was securely sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody setup.

Screening serves as a preliminary swift assessment for potential drug misuse. While cost-efficient, Screening demands a follow-up confirmation for court acceptance if a positive result arises. Samples hinting at positivity during Screening necessitate further confirmation.

Should a sample indicate positivity in the Screening phase, further hair is taken from the original sample for Extraction. This phase involves extracting substances from hair at much lower intensities compared to other methods like urine or oral fluid, a reason why hair drug analysis is notably challenging.

Confirmation of a positive screen result is executed via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples anticipated positive are cleansed ahead of confirmation when required. From Accessioning to Confirmation, the laboratory operations are scrutinized in accordance with both CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 requirements.

Hair drug testing benefits:

• Extended detection period: Hair tests can witness drug use over a span of up to 90 days, unlike urine tests which have a shorter examination period.
• Challenging to falsify: The accuracy of hair drug tests is heightened due to the difficulty in tampering with results.
• Illustrates historical usage: Hair tests unveil patterns of drug use over time, rather than only recent activities.

Drawbacks:

• Inability to detect recent use: Drugs typically appear in hair after 5-7 days.
• Expense: Hair tests are often costlier than alternative drug testing techniques.
• Result variability: Variables like hair color and individual growth rates can influence drug metabolite concentrative levels in hair.

Note: Although commonly labeled as "hair follicle tests", the examination actually evaluates the hair strand and not the scalp-based follicle.

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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
