Hair Follicle Drug Testing - Katalla, AK

What it is, How it works

Hair analysis has earned recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of substances by embedding biomarkers within the fibers of the growing hair. When sourced near the scalp, it provides a detection span of up to around three months for alcohol and drugs. Hair collection is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch segment comprising roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest the scalp can supply 100mg, the prime amount for both screening and confirmation. For EtG, additional testing, or tests exceeding 10 panels, 150mg is advisable. It's recommended to weigh the sample using a jewelry scale. If scalp hair is unavailable, a similar quantity of body hair may be gathered. References to head hair concern scalp strands alone, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The four primary phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab’s system. This process involves confirming that the sample was properly sealed and shipped, providing a random LAN (Laboratory Accessioning Number), and addressing any extra data entry that an electronic chain of custody system didn't cover.

Screening refers to an initial rapid evaluation for substance abuse. Although it’s a budget-friendly method to rule out drug use in the majority of cases, a positive screen requires confirmation for court validity. All samples flagged as presumptively positive during Screening necessitate a subsequent confirmation.

Should a specimen show a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are isolated from hair at a notably lower concentration than found in other approaches (e.g., urine or oral fluids), highlighting the complexity of hair drug screening as a methodology.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed pre-confirmation if necessary. The full lab procedure from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection: Hair drug tests detect drug intake up to 90 days, unlike urine tests with shorter detection windows.
• Harder to manipulate: Cheating a hair drug test is challenging, ensuring more reliable outcomes.
• Delivers historical insights: It showcases drug use patterns over time, not just recent consumption.

Drawbacks:

• Incapable of spotting recent consumption: It takes roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug testing typically costs more than other testing techniques.
• Outcome variability: Factors like hair color and personal differences in hair growth impact drug metabolite levels in hair.

Note: Commonly labeled "hair follicle tests," the test examines 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. 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.
