Hair Follicle Drug Testing - Le Moyen, LA

What it is, How it works

Hair assessments are recognized as a potent method for detecting drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug presence by embedding biomarkers within the fibers of the developing hair shaft. When retrieved near the scalp, it offers nearly a three-month detection timeframe for alcohol and drugs. The process of collecting samples is straightforward, somewhat resistant to tampering, and convenient to transport.

A segment of hair measuring 1.5 inches, approximately 200 strands (comparable to the thickness of a #2 pencil), closest to the scalp yields 100mg, which is the optimal amount for analysis and validation. For EtG, additional scopes, and/or evaluations surpassing 10 panels, 150mg of the material is advisable. It is suggested to weigh the material using a jeweler’s scale. Should scalp hair be lacking, an equivalent portion of body hair can be utilized. References to head hair imply scalp hair alone, while body hair pertains to all other hair categories (like facial or axillary).

Process Overview

The sequence of laboratory processes in assessing a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a specimen into a lab’s system. This process ensures the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any supplementary data input absent from an electronic chain of custody system.

Screening consists of a preliminary swift assessment for substance abuse. Despite Screening being a cost-efficient method for excluding drug use in most specimens, a positive finding must be confirmed for legal admissibility. Specimens presuming positive in Screening necessitate further confirmation.

If a specimen indicates a presumptive positive in Screening, additional hair is extracted from the original sample for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to alternative methods (e.g., urine or saliva), explaining why hair drug evaluations are the most challenging techniques to execute.

Validation of any positive result during screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumption-positive specimens are cleansed prior to validation as needed. The full laboratory protocol from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug use up to 90 days, unlike urine evaluations that have a briefer detection period.
• Challenging to evade: It is notably challenging to deceive a hair drug evaluation, enhancing result precision.
• Yields past usage data: It reveals a drug usage pattern over time, beyond mere recent consumption.

Limitations:

• Incapable of detecting recent consumption: Approximately 5-7 days are required for drugs to become apparent in hair.
• Expense: Hair drug evaluations are typically more costly than other testing methods.
• Variation in results: Elements like hair color and personal differences in hair growth may impact metabolite concentration in hair.

Note: Frequently termed as "hair follicle evaluations", the analysis is conducted on the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Le Moyen, LA

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.
