Hair Follicle Drug Testing - Spearsville, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying alcohol and drug consumption. Hair offers a comprehensive timeline of substance use by capturing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can reflect alcohol and drug use for a period of up to about 3 months. Collecting hair is straightforward, with minimal risk of tampering, and convenient to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil's diameter), can yield 100mg, the optimum amount for testing and verification. For EtG, additional panels or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler's scale is recommended for weighing the sample. In cases where scalp hair is not available, an equal quantity of body hair can be used. References to head hair pertain specifically to scalp hair, whereas body hair encompasses all other types such as facial or axillary hair.

Process Overview

The drug testing procedure in the laboratory involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary incorporation of a sample into the lab's system. This step includes ensuring the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any requisite data input not handled by an electronic chain of custody system.

Screening provides an initial rapid assessment for substance abuse. Although Screening offers a budget-friendly approach to dismiss drug use in the majority of cases, positive findings require confirmation to be valid in legal settings. Samples yielding a suspected positive result during Screening must undergo further confirmation.

Should a sample appear presumptively positive during Screening, additional hair is retrieved from the original sample for Extraction. During Extraction, substances are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected positive are cleansed before confirmation, when necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized in accordance with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug analysis can trace drug use for up to 90 days, whereas urine tests have a shorter detection window.
• Difficulty to cheat: It is highly challenging to manipulate a hair drug test, resulting in more reliable outcomes.
• Provides historical data: It demonstrates a drug use pattern over time, instead of merely recent use.

Limitations:

• Cannot detect recent use: It requires around 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests typically cost more than other drug testing techniques.
• Variations in results: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests", the evaluation is conducted on the hair strand rather than the hair 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.
