Hair Follicle Drug Testing - Berkley, IA

What it is, How it works

Recognized as a potent instrument in identifying drug and alcohol consumption, hair analysis captures a comprehensive history by encasing biomarkers within the developing hair strand's fibers. When hair is sourced near the scalp, it can reveal a usage span of nearly three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.

Collecting a 1.5-inch segment of approximately 200 hair strands (equivalent to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, supplemental tests, or analyses beyond 10 panels, 150mg of the specimen is advisable. It is suggested to measure the specimen's weight using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair might be sourced. Head hair references are specific to scalp hair alone. On the other hand, body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial integration into a lab's system. The process includes ensuring the sample’s appropriate sealing and dispatch, generating a random LAN (Laboratory Accessioning Number), and completing any extra data documentation absent in an electronic chain of custody setup.

Screening conducts a preliminary swift examination for drugs of abuse. Though Screening is a budget-friendly method to exclude drug intake from most samples, court eligibility requires a positive screen's confirmation. Samples indicated as presumptively positive during Screening necessitate a subsequent confirmation process.

For samples indicated as presumptively positive in Screening, additional hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are withdrawn from hair at a much lower concentration compared to other techniques (e.g., urine or oral fluid), explaining why hair drug screening is among the most challenging methods to accomplish.

Confirmation for any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive specimens are cleansed before confirmation as required. The entire progression from Accessioning to Confirmation is subjected to scrupulous review under the CAP (College of American Pathologists) Hair designation and acquiescence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug assessments can identify drug consumption up to 90 days, unlike urine assessments which offer a reduced detection span.
• Difficulty to cheat: The difficulty in manipulating a hair drug test contributes to heightened accuracy of results.
• Provides historical data: It reflects a timeline of drug use over time, rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Cost: Generally, hair drug tests entail a higher cost compared to other testing modalities.
• Variations in results: Aspects like hair color and individual nuances in hair growth can influence drug metabolite concentration in the hair.

Note: Commonly called "hair follicle tests", the examination pertains to analyzing the hair strand rather than the hair 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.
