Hair Follicle Drug Testing - Tanglewilde, WA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands can trap biomarkers over time, providing a comprehensive record of drug usage. When collected from near the scalp, hair can indicate drug and alcohol presence for about three months. The collection process is straightforward, the risk of sample tampering is lower, and transportation is convenient.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable in width to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for drug screening and confirmation. For EtG, additional tests, or when testing beyond 10 panels, 150mg is suggested. It's advisable to weigh the sample with a jeweler’s scale. In cases where scalp hair is not available, similar quantities of body hair are acceptable. References to head hair imply scalp hair exclusively, whereas body hair includes all other types (e.g., facial, axillary, etc.).

Process Overview

Drug test results are processed through four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the integration of a sample into the lab system. This process verifies proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry omitted by an electronic chain of custody system.

Screening involves a rapid check for drug presence. While Screening is an economical method for eliminating drug usage in most cases, a positive screening result must be confirmed to be legally valid. All samples with a presumptive positive require further confirmation.

Should a sample show a preliminary positive in Screening, additional hair from the initial sample is prepared for Extraction. At this point, drugs are separated out from hair at a lower concentration than seen with other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.

Any positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo washing before confirmation as required. From start through to Confirmation, the lab procedure is examined under both the CAP (College of American Pathologists) Hair designation and is also accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use over up to 90 days, unlike urine tests which have a shorter detection window.
• Difficult to tamper with: Cheating a hair drug test is challenging, enhancing the accuracy of results.
• Reveals usage patterns: Allows for identifying drug use trends over time, not just current use.

Limitations:

• Not suited for recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests generally cost more than other testing approaches.
• Variable results: Variations such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Despite often being termed as "hair follicle tests", the analysis is performed 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.
