Hair Follicle Drug Testing - Carlisle, LA

What it is, How it works

The application of hair testing has increasingly been recognized as an effective method for detecting drug and alcohol consumption. Hair can chronicle long-term alcohol and drug use by capturing biomarkers within the fibers of the hair as it grows. When samples are taken near the scalp, hair can reveal drug and alcohol usage over roughly a 3-month period. Collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A hair sample measuring 1.5 inches in length consisting of around 200 strands (approximately matching the thickness of a #2 pencil) collected closest to the scalp provides 100mg of hair, which is the optimal weight for both screening and confirmation. For tests involving EtG, add-ons, and/or panels exceeding 10, a specimen weighing 150mg is advisable. It's suggested to use a jeweler’s scale for accurate weighing. If scalp hair is not available, an equivalent amount of body hair can be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial hair, axillary hair, etc.).

Process Overview

The laboratory drug test processing includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning requires the preliminary input of a test sample into a laboratory system. This stage ensures that the sample is properly sealed and shipped, assigns it a random LAN (Laboratory Accessioning Number), and completes additional data entry absent from the electronic chain of custody system.

Screening involves a preliminary evaluation to check for drugs of misusage. Although Screening offers a financially-efficient strategy to dismiss drug use in most samples, any positive result from the screen needs verification before it is court-admissible. Samples with presumptive positive results from Screening necessitate further confirmation.

Upon a presumptive positive outcome in the Screening phase, additional hair is sourced from the initial sample and prepped for Extraction. In this procedure, drug levels are drawn from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging methodology.

Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS or LC/MS/MS. Samples identified as presumptively positive undergo a wash before confirmation where needed. The entire lab processing workflow, from Accessioning to Confirmation, is governed by the CAP (College of American Pathologists) Hair classification and aligns with ISO / IEC 17025 standard requirements.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests permit drug detection over a span of up to 90 days, in contrast to urine tests with shorter detection periods.
• Resistance to manipulation: The difficulty of manipulating a hair drug test enhances the precision of results.
• Gives historical context: It offers an insight into drug usage trends across a duration, not confined to recent use only.

Limitations:

• Inability to catch recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variability: Variations like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Despite common references to "hair follicle tests", the analysis focuses on the hair shaft rather than the follicle beneath the scalp.

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.
