Hair Follicle Drug Testing - Lake City, PA

What it is, How it works

Regarded as a formidable means to uncover drug and alcohol consumption, hair analysis offers an extended historical view by capturing biomarkers within the strands' growing fibers. When hair is gathered near the scalp, it enables a detection period of up to three months for substances like alcohol. It's straightforward to obtain, not easy to tamper with, and convenient to send.

By taking a 1.5-inch section of around 200 hairs (comparable to the girth of a #2 pencil) nearest the scalp, you'll attain 100mg of hair, ideal for both screening and confirmation. For EtG alterations and exams exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing is suggested. If no scalp hair is present, equivalent body hair is suitable for testing. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

In lab analysis of a drug test outcome, four primary phases exist: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a specimen into a lab’s processing sequence. This involves verifying that the specimen was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic chain of custody mechanism.

Screening entails a rapid evaluation for substance abuse presence. Though a thrifty approach to eliminate drug use in most cases, any positive findings mandate verification for legal acceptance. Samples producing positive signals in Screening require a follow-up confirmation.

Upon a positive indication at Screening, additional hair is extracted from the primary sample to prepare for Extraction. Here, substances are isolated from hair at concentrations significantly lower compared to other methods (such as urine or saliva), underscoring the complexity of hair drug analysis.

Confirmation of initial positive findings is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with positive preliminary results undergo washing preceding confirmation as necessary. From Accessioning to Confirmation, the entire lab procedure is scrutinized in line with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection span: Hair drug assessments can trace substance usage for up to 90 days, whereas urine tests offer a shorter timeframe.
• Tricky to falsify: Hair drug tests are challenging to manipulate, making the results more credible.
• Presents usage patterns: It reflects drug usage over time, not just recent activity.

Drawbacks:

• Cannot detect immediate use: It requires about 5-7 days for substances to register in hair.
• Expense: Typically, hair drug tests are costlier compared to alternative testing methods.
• Result variability: Elements such as hair hue and individual growth differences can influence drug metabolite levels in hair.

Note: Despite being colloquially termed "hair follicle tests", the examination targets the hair strand itself, not the sub-scalp 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.
