Hair Follicle Drug Testing - St. James, LA

What it is, How it works

Hair analysis is now recognized as a formidable method for detecting alcohol and drug usage. By capturing biomarkers within the fibers of growing hair strands, it offers a longer-term account of substance use. When cut near the scalp, hair can indicate alcohol and drug consumption for up to a 90-day period. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch segment of nearly 200 hairs (around the size of a #2 pencil) nearest to the scalp equals 100mg, the perfect amount for preliminary and confirmatory testing. For EtG, supplementary tests, and/or panels exceeding ten, 150mg is preferable. We advise using a jeweler’s scale for weighing. If scalp hair isn’t an option, an equivalent quantity of body hair can be taken. When we mention head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial or axillary hair).

Process Overview

The core procedures involved in the lab processing of drug tests are Accessioning, Screening, Extraction, and Confirmation.

Accessioning requires entering a sample into a lab’s management system, ensuring the sample was appropriately sealed and delivered, issuing a random LAN (Laboratory Accessioning Number), and adding any missing data not included in an electronic chain of custody.

Screening provides an initial expedient evaluation for drugs. Although Screening is a cost-effective means to dismiss drug presence in many samples, a conclusive result needs further verification to stand in court. Samples with a presumptive positive in Screening need additional confirmation.

In the event of a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly reduced concentrations than in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging procedure.

Confirmation for positive screens is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleaned if necessary before confirmation. The comprehensive lab procedure from Accessioning through to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can reveal drug usage for up to 90 days, unlike urine tests with shorter windows.
• High integrity: It's exceedingly challenging to falsify a hair drug test, yielding more reliable results.
• Historical pattern: It demonstrates drug usage tendencies over time, not just recent activity.

Limitations:

• Unable to detect immediate use: It typically takes 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests generally cost more than alternative testing approaches.
• Result variability: Elements like hair color and individual differences in hair growth may influence drug metabolite levels in hair.

Note: Despite often being called "hair follicle tests", these tests evaluate the hair strand and not 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.
