Hair Follicle Drug Testing - Jonesville, LA

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol use. Hair strands serve as a long-term repository for alcohol and drug biomarkers, encased within the fibers of the growing hair. When hair samples are collected near the scalp, they offer a detection range extending up to nearly 90 days for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg, the preferred quantity for analyses and confirmation. For tests inclusive of EtG, additional elements, or more than 10 panels, 150mg of the sample is advised. It's recommended to use a jeweler’s scale for precise weighing. In cases where scalp hair is not accessible, a comparable quantity of body hair can serve as a substitute. References to head hair pertain exclusively to scalp hair. Body hair encompasses all non-scalp hair types (such as facial, and axillary).

Process Overview

Laboratory drug test processing is comprised of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the lab's system. This step entails confirming proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody.

Screening provides an initial quick check for substances of misuse. While cost-efficient for excluding drug presence in most cases, positive results during Screening require confirmation to hold in legal contexts. Presumptive positives identified in Screening necessitate further verification.

For samples with presumptive positives in Screening, additional hair is sourced from the original sample for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or saliva), making hair drug screening a more complex method to execute.

Confirmation of positive screens is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings are cleaned before confirmation if necessary. The complete lab process from Accessioning to Confirmation is reviewed following the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests trace drug use over a 90-day period, unlike urine tests with a limited window.
• Hard to bypass: Cheating a hair drug test is extremely challenging, enhancing result reliability.
• Shows historical usage: It reveals patterns of drug consumption over time, not merely recent use.

Limitations:

• Cannot trace immediate usage: Drug presence in hair takes roughly 5-7 days to become detectable.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth can influence drug metabolite levels in hair.

Note: Although often referred to as "hair follicle tests", the testing examines the strand itself, not the hair follicle below 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.
