Hair Follicle Drug Testing - Port Angeles East, WA

What it is, How it works

Hair testing is recognized as a robust method to identify drug and alcohol consumption. Hair captures a historical record of these substances by enclosing biomarkers within the strands' fibers. When harvested near the scalp, hair offers a roughly 3-month detection period for alcohol and drugs. It's straightforward to collect, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches with about 200 hair strands (comparable to a #2 pencil's size) near the scalp yields 100mg of hair, perfect for screening and confirmation processes. For EtG, enhancements, and/or tests exceeding 10 panels, 150mg is advised. Using a jeweler's scale to weigh the sample is suggested. Should scalp hair be unavailable, equivalent amounts of body hair can be used. References to head hair specifically mean scalp hair only. Body hair includes other types (like facial, axillary, etc.).

Process Overview

The four core steps in analyzing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample is first processed within the lab's system. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data entry absent in an electronic chain of custody process.

Screening provides an initial rapid assessment for drug abuse. While it's a cost-efficient method to eliminate drug use in most samples, any positive Screening results need confirmation to be valid legally. Samples that test presumptively positive during Screening require additional confirmation.

For presumptively positive samples in the Screening phase, additional hair is retrieved from the initial sample for Extraction. Here, drugs are taken from hair at much lower concentrations than seen in other methods (like urine or oral fluid), making hair drug testing the most challenging to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used to confirm any positive screenings. Presumptively positive samples undergo washing before confirmation, if necessary. The lab procedure from Accessioning to Confirmation follows both CAP (College of American Pathologists) guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests trace drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, ensuring more precise results.
• Provides historical data: It shows a usage pattern over time, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs require approximately 5-7 days to appear in hair.
• Cost: Hair drug testing is typically costlier than other testing methods.
• Variations in results: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although termed "hair follicle tests," the analysis focuses on the hair strand, not the follicle below 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
