Hair Follicle Drug Testing - Labadieville, LA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair can record long-term usage of alcohol and other substances by embedding biomarkers within the growing hair strand's fibers. When obtained near the scalp, hair can offer up to a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (about the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For tests like EtG, add-ons, or those with more than 10 panels, a specimen of 150mg is advised. Our recommendation is to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equal quantity of body hair can be collected. Reference to head hair implies only scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug test result in a laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial assimilation of a sample into a lab’s system. This includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for substances of abuse. Although Screening is a cost-effective means to exclude drug usage in most samples, a positive screening result must be verified for legal admissibility. Samples presumed positive in Screening need further confirmation.

For samples presumed positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are isolated from hair at a much lower concentration than in other techniques (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.

Verification of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positives undergo washing before confirmation if necessary. The end-to-end lab processing from Accessioning to Confirmation is regulated under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage up to 90 days, in contrast to urine tests which have a shorter detection period.
• Hard to falsify: The difficulty in cheating a hair drug test makes the outcomes more reliable.
• Delivers historical insights: It provides a chronic pattern of drug use, rather than just recent consumption.

Limitations:

• Inability to ascertain recent use: Detection of substances in hair takes around 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the procedure examines the hair strand, not 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.
