Hair Follicle Drug Testing - Thompsons, TX

What it is, How it works

In the realm of drug and alcohol detection, hair testing has emerged as a formidable asset. The fibers of growing hair strands capture biomarkers, offering a historical account of substance use. When sampled near the scalp, it can unveil a drug and alcohol detection window of roughly three months. Collecting hair is straightforward, challenging to tamper with, and facilitates easy shipping.

A hair sample measuring 1.5 inches, consisting of approximately 200 strands (akin to the size of a #2 pencil), yields 100mg of hair, which is the prime quantity for both screening and confirmation. For tests involving EtG, add-ons, and/or more than 10 panels, a specimen weighing 150mg is advisable. We advocate using a jeweler’s scale for specimen weighing. Should scalp hair be unattainable, a comparable amount of body hair can be gathered. To clarify, head hair exclusively refers to scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Summary

The laboratory procedures for processing a drug test result involve four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial integration of a sample into a lab's system. This entails ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody system.

Screening constitutes an initial rapid assessment for substance abuse. While Screening efficiently excludes drug use in most samples cost-effectively, a confirmed result is necessary for court admissibility. Samples that are tentatively positive during Screening mandate subsequent confirmation.

When a sample indicates potential positivity during the Screening phase, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), underpinning hair drug screening's reputation as a challenging methodology.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive results observed during screening. All samples presumably positive necessitate a cleansing process before confirmation. The complete lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection timeline: Hair drug tests can recognize drug intake for up to 90 days, unlike urine tests which have a briefer detection period.
• Hard to deceive: Cheating on a hair drug test is exceptionally challenging, enhancing result credibility.
• Shows historical trends: It illustrates patterns of drug consumption over time, not merely recent use.

Drawbacks:

• Incapable of recognizing recent consumption: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Elements like hair color and individual disparities in hair growth can influence drug metabolite concentrations in hair.

Word of caution: Despite being labeled 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.
