Hair Follicle Drug Testing - Napoleonville, LA

What it is, How it works

Hair testing emerges as a robust means for uncovering drug and alcohol usage. Hair offers an extended history of substance consumption by ensnaring biomarkers within growing hair fibers. When hair is taken near the scalp, it can present up to an approximate three-month window of detection for various substances. The collection of hair is straightforward, relatively hard to tamper with, and convenient to dispatch.

A 1.5-inch segment comprising roughly 200 hair strands (around the same girth as a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the optimal sample for initial screening and verification. For EtG, additional testing, and/or tests exceeding 10 panels, a 150mg sample is advised. It is suggested to use a jeweler’s scale for measuring the sample weight. If scalp hair cannot be obtained, a similar quantity of body hair is acceptable. The term head hair specifically pertains to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four principal phases in the lab processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary handling of a sample into a lab's system. This phase ensures the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not handled by an electronic chain of custody protocol.

Screening acts as an initial rapid assessment for substance misuse. Although screening is a cost-efficient method to exclude drug use in most samples, a confirmed positive result is necessary for court admissibility. Any samples with a presumptive positive in Screening require subsequent confirmation.

Should a sample show a presumptive positive in Screening, additional hair is extracted from the initial sample and readied for Extraction. Within this phase, drugs are isolated from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), hence making hair drug screening the most challenging method to execute.

Any positive screening confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if needed. The full lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection timeframe: Hair drug tests can determine drug usage for up to 90 days, contrary to urine tests which possess a briefer detection span.
• Hard to manipulate: Manipulating a hair drug test is exceedingly challenging, thus results tend to be more precise.
• Supplies historical insight: It provides a record of drug use across time, not merely recent consumption.

Limitations:

• Unable to detect recent use: It takes about 5-7 days for substances to become noticeable in hair.
• Expense: Hair drug tests generally incur greater costs than other drug testing techniques.
• Outcome variance: Elements like hair color and individual variability in hair growth may influence the concentration of drug metabolites in the hair.

Note: Although frequently recognized as "hair follicle tests", the assessment itself examines the hair strand rather than the scalp’s hair 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.
