Hair Follicle Drug Testing - Walla Walla East, WA

What it is, How it works

Hair testing has gained recognition as an effective mechanism for identifying drug and alcohol consumption. This method captures a comprehensive timeline of alcohol and other drugs by embedding biomarkers in the fibers of the hair shaft as it grows. When obtained near the scalp, hair samples can offer a detection range of up to about 3 months for substances like alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch segment comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg, which is considered the optimal quantity for testing and confirmation. For EtG, add-on tests, and/or panels exceeding 10, a 150mg sample is preferable. Using a jeweler’s scale, we suggest validating the specimen's weight. If head hair is inaccessible, an equivalent volume of body hair can be used. "Head hair" specifically pertains to scalp hair, while "body hair" encompasses all other variants (such as facial and axillary hair).

Process Overview

The drug test outcome in the lab is processed through four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample enters a lab's system. This step includes confirming that the sample was adequately sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and performing any extra data input absent from an electronic chain of custody framework.

Screening serves as an initial, rapid evaluation for drug presence. Although Screening is a cost-effective method to dismiss drug usage in most cases, any positive findings require confirmation for legal admissibility. Samples that are initially deemed positive in Screening necessitate further validation.

In instances where Screening indicates a presumptive positive, extra hair is extracted from the original specimen for Extraction preparation. At this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screenings.

To confirm any positive Screenings, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Presumptive positive samples are cleansed before verification as needed. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use dating back up to 90 days, unlike urine tests that have a more limited timeframe.
• High resistance to tampering: Manipulating a hair drug test is quite challenging, enhancing result accuracy.
• Chronic usage pattern: This testing provides insights into long-term drug use trends rather than just recent consumption.

Limitations:

• Inability to detect recent ingestion: It takes about 5-7 days for substances to become traceable in hair.
• Expense considerations: Hair drug testing generally incurs higher costs compared to alternative testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth rates can influence drug metabolite levels in hair.

Note: Despite the moniker "hair follicle tests", the examination is conducted on 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.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
