Hair Follicle Drug Testing - Nenzel, NE

What it is, How it works

Hair testing is recognized as a potent method for detecting drug and alcohol consumption. Hair offers an extended chronological record of substance use by preserving biomarkers within the fibers of the growing hair strand. When cut close to the scalp, hair can signal substance use within an approximately 3-month detection period. It is effortless to collect, challenging to tamper with, and simple to transport.

Collecting a 1.5-inch sample of around 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for screening and validation. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen of 150mg is suggested. Utilizing a jeweler’s scale is advised for weighing the specimen. If scalp hair isn't an option, a comparable amount of body hair is applicable. When mentioning head hair, it pertains solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The principal steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is processed into the lab's system. It involves checking that the sample was properly sealed and shipped, designating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry absent from an electronic chain of custody system.

Screening constitutes an initial swift assessment for drugs of abuse. While Screening is a cost-efficient technique to negate drug use in most samples, any positive result requires confirmation to be court-admissible. Samples that indicate presumptive positivity in Screening necessitate secondary confirmation.

If Screening results in a presumptive positive, further hair is drawn from the original sample and readied for Extraction. This phase involves removing drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug use for up to 90 days, contrasting with urine tests that provide a shorter detection window.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, ensuring the results' precision.
• Provides historical data: It delivers a blueprint of drug use over time, not merely recent activity.

Limitations:

• Cannot detect recent use: It requires roughly 5-7 days for substances to become detectable in hair.
• Cost: Hair drug testing tends to be pricier compared to alternative drug testing methods.
• Variations in results: Factors like hair color and individual growth patterns can impact drug metabolite concentrations in hair.

Note: Despite often being termed as "hair follicle tests", the test examines the hair strand rather than 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.
