Hair Follicle Drug Testing - Calcasieu, LA

What it is, How it works

Hair evaluations have gained recognition as a critical means for detecting substance and alcohol consumption. Hair offers an extended record of alcohol and other substances by capturing biomarkers within the growing strand fibers. When cut close to the scalp, it can reveal a detection window of up to roughly 90 days for both alcohol and other substances. Hair sampling is straightforward, relatively tamper-proof, and convenient for shipping.

An optimal sample consists of a 1.5-inch section of roughly 200 hair strands (equivalent to a #2 pencil's girth) nearest the scalp, yielding 100mg—the preferred amount for screening and validation. For EtG enhancements or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for specimen weighing is recommended. If scalp hair is absent, a similar mass of body hair can be harvested. References to head hair are exclusively about scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The core stages in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into lab operations. This task includes confirming the seal and proper shipment of the sample, the issuance of a unique LAN (Laboratory Accessioning Number), and completing extra data entry not managed by an electronic chain of custody system.

Screening performs an initial rapid assessment for substance abuse. Despite being economical for excluding drug use in most samples, any positive screen needs confirmation to stand in legal settings. All presumptive positives in Screening necessitate subsequent verification.

Should a sample yield a positive result in Screening, further hair is appropriated from the original specimen and readied for Extraction. During this phase, substances are derived from hair at a considerably lower concentration than other methods (such as urine or saliva), explaining the complexity of hair drug screening procedures.

GC/MS, GC/MS/MS, or LC/MS/MS are utilized to affirm any positive screen results. Before confirmation, all presumptive positives undergo washing as required. The entire procedure from Accessioning through to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug utilization for up to 90 days, surpassing urine tests' shorter timeframe.
• Minimal risk of deception: Manipulating a hair drug test is challenging, ensuring more precise outcomes.
• Offers historical insight: It can delineate a drug usage pattern over a timeframe, not solely recent intake.

Limitations:

• Incapable of identifying recent consumption: It takes close to 5-7 days before substances are traceable in hair.
• Expense: Hair drug testing typically costs more than other methods.
• Results variability: Variables like hair pigmentation and individual hair growth differences can influence drug metabolite concentration.

Note: Referred to as "hair follicle tests", these tests inspect the hair strand itself, 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.
