Hair Follicle Drug Testing - Copalis Beach, WA

What it is, How it works

Hair testing is increasingly recognized as a potent means for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug markers by embedding them within the strands as they grow. When cut near the scalp, hair samples can indicate drug and alcohol presence over a span of up to three months. Hair collection is straightforward, somewhat challenging to tamper with, and convenient for shipping.

A 1.5-inch section of approximately 200 hair strands (roughly similar to a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred amount for both screening and confirmation. For EtG, add-ons, and tests requiring more than 10 panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not accessible, a comparable quantity of body hair can be used. Mention of head hair specifically denotes scalp hair. Body hair encompasses all other hair categories (such as facial and axillary hair).

Process Overview

Lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with the sample being entered into the lab’s system. This process includes ensuring the sample’s seal and shipment are intact, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.

Screening provides an initial swift assessment for drug presence. While this process is cost-efficient for dismissing drug use in most samples, positive results from Screening must be validated to ensure legal admissibility. Presumptive positive samples identified during Screening necessitate further confirmation.

On receiving presumptive positive results during Screening, additional hair is extracted from the primary sample for Extraction. During this phase, drugs are drawn from the hair at noticeably lower concentrations compared to other methods (like urine or oral fluid), highlighting why hair drug screening is considered the most intricate technique to administer.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used for confirming positive screening outcomes. All samples preliminarily positive are cleansed before confirmation on an as-needed basis. The complete laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter detection durations.
• Hard to tamper with: Cheating a hair drug test is extremely challenging, ensuring more precise results.
• Reveals past patterns: Displays a history of drug use over time rather than only recent consumption.

Limitations:

• Recent use not detectable: Drugs take roughly 5-7 days to manifest in hair strands.
• Expense: Hair drug testing tends to be costlier compared to other testing approaches.
• Result variability: Variations in hair color and individual hair growth can influence drug metabolite concentrations in hair.

Note: While commonly called "hair follicle tests", the analysis focuses on the hair strand itself, 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. 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.
