Hair Follicle Drug Testing - Coahoma, TX

What it is, How it works

The assessment of hair has become recognized as a robust instrument for identifying drug and alcohol consumption. Hair captures a longitudinal record of alcohol and other substance usage by embedding biomarkers within the strands' fibers as they grow. When sourced near the scalp, hair can showcase a detection timeline reaching nearly three months for both alcohol and other drugs. Gathering hair is straightforward, fairly resilient to tampering, and convenient for transport.

A 1.5-inch segment, consisting of about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, the perfect amount for both screening and confirmation. For EtG, additional analyses, or tests surpassing ten panels, a 150mg sample is preferred. We advise utilizing a jeweler’s scale to weigh the specimen. Should scalp hair not be present, a proportional quantity of body hair might be taken. 'Head hair' strictly implies scalp hair. 'Body hair' encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The procedural sequence in laboratory evaluation of drug testing results includes four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample in a lab's framework. This phase involves ensuring the sample was correctly sealed and transported, granting a random LAN (Laboratory Accessioning Number), and performing further data entry absent from an electronic chain of custody form.

Screening refers to an initial rapid assessment of substance misuse. Although Screening is a cost-efficient strategy to exclude drug use for most samples, positive screenings necessitate verification for court acceptance. Any samples that are positively suggested during Screening mandate subsequent confirmation.

Upon suggesting positivity in the Screening phase, additional hair from the original sample is utilized for Extraction preparation. This stage involves drug retrieval from the hair at notably lower concentrations than other methods (such as urine or oral fluid), explaining the complexity associated with hair drug screening.

Confirming any positive screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive undergo washing before confirmation if necessary. The complete lab procedure, spanning from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair categorization and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can trace drug use over a 90-day period, unlike urine testing, which has a narrower detection span.
• Cheating resistance: Cheating on a hair drug test is extremely challenging, ensuring higher accuracy in results.
• Historical insight: It provides a historical perspective on drug consumption trends, beyond just recent intake.

Limitations:

• Recent use undetectability: A period of roughly 5-7 days is needed for drugs to become traceable in hair.
• Expense: Hair drug testing tends to have higher costs compared to alternative drug testing approaches.
• Result variability: Influences like hair color and personal variations in hair growth rates can impact drug metabolite concentration in hair.

Note: Though commonly referenced as "hair follicle tests", the analysis targets the hair strand, 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.
