Hair Follicle Drug Testing - Montpelier, LA

What it is, How it works

Hair testing is increasingly recognized as an effective means of identifying alcohol and drug use. Hair offers a comprehensive history of substance use by capturing biomarkers within its growing strands. When fetched near the scalp, hair can offer nearly a three-month time frame for detecting drugs and alcohol. Collecting hair is straightforward, relatively tough to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample for initial and confirmatory testing. For tests such as EtG or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, an equivalent quantity of body hair may be used. When referring to head hair, we mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four core steps in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial sample processing within a laboratory's framework. This process involves validating that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system may not cover.

Screening includes a preliminary, swift evaluation for drugs of abuse. Though Screening is a cost-efficient method to eliminate drug usage for most samples, a positive screen requires confirmation to be valid in legal contexts. Any samples preliminarily positive in Screening require subsequent confirmation.

If a sample is preliminarily positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. This stage involves extracting drugs from the hair at much lower concentrations than other methods (like urine or oral fluid), underscoring why hair drug screening presents the most challenge to execute.

Confirmation for any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo washing before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards for accreditation.

Benefits of hair drug testing:

• Extended detection window: Hair drug testing can detect drug employment for up to 90 days, unlike urine tests that offer a shorter detection span.
• Resistance to tampering: Cheating a hair drug test is exceedingly challenging, thus enhancing result accuracy.
• Delivers historical insight: It can reveal a user’s drug use pattern over time, not just immediate usage.

Challenges:

• Incapable of detecting recent usage: It typically takes 5-7 days for drugs to become detectable in hair strands.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result discrepancies: Variables such as hair color and individual differences in hair growth can influence the concentration of drug metabolites within hair.

Note: While frequently identified as "hair follicle tests", the test actually assesses the hair strand instead of 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.
