Hair Follicle Drug Testing - Hauser, OR

What it is, How it works

The utilization of hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair retains a comprehensive history of substance use by embedding biomarkers within the hair strand fibers as they grow. When taken near the scalp, hair can reveal drug and alcohol usage within roughly a 3-month timeframe. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches, comprising nearly 200 hair strands (comparable to a #2 pencil), collected nearest to the scalp yields 100mg of hair, ideal for both screening and confirming results. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler's scale. Should scalp hair be unavailable, an equivalent body hair amount may be used. When mentioning head hair, we specifically mean scalp hair; body hair refers to all other types (facial, axillary, etc.).

Process Overview

The core phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab's system. It entails verifying that the sample is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry omitted from an electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs of abuse. While Screening is a budget-friendly method to eliminate drug presence in most samples, any positive finding needs confirmation for legal admissibility. Samples that are presumptively positive in Screening require an additional confirmation step.

If a sample yields a presumptive positive in the Screening phase, further hair is extracted from the original sample for the Extraction phase. Here, hair undergoes drug extraction at a much-diluted concentration compared to other methods (e.g., urine or oral fluid), illustrating why hair drug screening is among the most challenging testing methodologies.

Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS or LC/MS/MS. All samples preliminarily positive are cleansed before confirmation if necessary. The complete lab procedure from Accessioning through Confirmation is overseen following the CAP (College of American Pathologists) Hair criteria and in alignment with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can find drug use up to 90 days back, unlike urine tests with shorter detection periods.
• Hard to falsify: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Offers trend analysis: It sheds light on drug use patterns over time, not just recent use.

Limitations:

• Incapable of spotting recent consumption: Drugs become detectable in hair around 5-7 days post-usage.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements such as hair color and individual hair growth differences can alter the drug metabolite concentration found in the hair.

Note: Although often dubbed "hair follicle tests", the examination actually analyzes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

How does hair follicle testing outshine urine tests in Hauser, OR? The superiority lies in its robust detection accuracy.

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
