Hair Follicle Drug Testing - Toro, LA

What it is, How it works

Hair analysis has become recognized as an effective instrument for identifying substance and alcohol consumption. A hair strand captures a historical record of alcohol and drug use by embedding biomarkers within its fibers. When obtained near the scalp, hair offers nearly a 90-day window to detect alcohol and drugs. Collecting hair is straightforward, tampering is relatively challenging, and transportation is convenient.

An ideal specimen consists of a 1.5-inch sample, approximately 200 strands, akin to a #2 pencil's diameter. This yields 100mg of hair, optimal for initial screening and subsequent confirmation. For tests involving EtG, additional panels beyond 10 require at least 150mg. Using a jeweler's scale for accuracy is advisable. If scalp hair is not accessible, equivalent body hair can be used. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses other types (e.g., facial or axillary).

Process Overview

The four pivotal phases in processing a laboratory drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the sample's introduction into the lab's system, ensuring it was sealed and dispatched correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any data entry absent from an electronic custody chain.

Screening provides a preliminary assessment for substance abuse. Though cost-efficient for dismissing drug presence in most samples, a positive screening necessitates confirmation for legal admissibility. Samples preliminarily positive in Screening mandate a follow-up confirmation.

With a potential positive from Screening, additional hair is taken from the sample and prepared for Extraction. Here, substances are extracted at significantly lower concentrations than other methods (like urine or oral fluids), highlighting hair screening's complexity.

Confirmation of any positive screens relies on GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suggesting a positive impact undergo washing before confirmation. The entire process from Accessioning through Confirmation is scrutinized under 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 track drug use up to 90 days, unlike urine tests with shorter detection spans.
• Resistance to manipulation: Cheating a hair drug test is challenging, thereby increasing result reliability.
• History provision: It discloses drug use patterns over time, beyond recent activity.

Limitations:

• Inability to reflect recent consumption: It requires around 5-7 days for drugs to appear in hair tests.
• Expense: Hair tests tend to be pricier than other drug testing techniques.
• Result variability: Hair color and growth differences can influence metabolite concentration.

Note: Commonly termed "hair follicle tests", this method examines the hair shaft rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Toro, LA, the former offers marked advantages.

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.
