Hair Follicle Drug Testing - Arroyo Gardens, TX

What it is, How it works

Hair testing is increasingly regarded as a highly effective method for identifying drug and alcohol consumption. It provides a comprehensive historical profile of substances like alcohol, by capturing biomarkers within the hair strands as they grow. When sampled near the scalp, hair can reveal a drug or alcohol use timeline spanning up to 3 months. The collection process is straightforward, resistant to tampering, and easy to transport.

A 1.5-inch segment containing roughly 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp offers 100mg, which is an optimal amount for both screening and verification processes. In cases involving EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. We advise the use of a jeweler’s scale for precise measurement. If scalp hair is unavailable, a comparable quantity of body hair can be utilized. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The drug testing in laboratories unfolds over four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a laboratory's workflow. This step involves ensuring the sample's seal and shipping integrity, allocating a unique LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entries not already recorded through an electronic chain of custody system.

Screening entails a rapid preliminary assessment for drugs of abuse. Though Screening efficiently rules out drug usage in most samples, a positive result necessitates confirmation for legal admissibility. Samples yielding a presumptive positive result during Screening require further validation.

For samples registering a presumptive positive in Screening, additional hair from the initially collected sample is prepared for Extraction. This phase isolates drugs from hair, albeit at lower concentrations compared to urine or oral fluid testing, underscoring the complexity of hair drug screening.

Positive screening results undergo Confirmation using tools like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as required. The full laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug consumption up to 90 days back, unlike urine tests with narrower detection periods.
• Hard to manipulate: Cheating a hair drug test is exceedingly challenging, ensuring greater result accuracy.
• Chronological data: It can depict a substance use trajectory over time rather than solely detecting recent use.

Limitations:

• Incapable of detecting recent usage: It typically takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug assessments generally demand higher costs than other testing approaches.
• Result variability: Differences such as hair color and individual growth rates may impact drug metabolite concentrations within hair.

Note: While commonly called "hair follicle tests", the analysis focuses on the hair strand itself, excluding 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.
