Hair Follicle Drug Testing - Minnewaukan, ND

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair serves as a historical record for alcohol and other substances by embedding biomarkers within the strands of hair as they grow. When harvested near the scalp, hair can reveal a detection window of up to about three months for alcohol and other substances. This method is straightforward to collect, challenging to tamper with, and convenient to transport.

An optimal sample for screening and confirmation consists of a 1.5-inch section of roughly 200 hair strands (approximating the width of a #2 pencil) nearest to the scalp, totaling 100mg of hair. For EtG, additional tests, or examinations exceeding 10 panels, 150mg of the sample is advised. It is recommended to measure the specimen using a jeweler’s scale. If head hair cannot be retrieved, a comparable amount of body hair is permissible. When discussing head hair, only scalp hair is addressed. Body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing phase of a sample in a lab’s system. This step verifies the appropriate sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes additional data input that the electronic chain of custody system may not provide.

Screening executes a swift preliminary check for drug misuse. While cost-efficient for excluding drug use in most samples, a positive screen necessitates confirmation for courtroom eligibility. Any samples with presumptive positive results in Screening mandate secondary confirmation.

For samples with presumptive positives in the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. During Extraction, substances are isolated from hair at significantly lower concentrations compared to other methods such as urine or oral fluid, rendering hair drug screening one of the most complex methodologies.

Positive screening confirmation is achieved via GC/MS, GC/MS/MS, or LC/MS/MS processes. Presumptive positive samples undergo washing before confirmation as required. The comprehensive laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can indicate substance use for up to 90 days, as opposed to urine tests with much shorter detection timelines.
• Hard to manipulate: Cheating a hair drug test presents high difficulty, enhancing result precision.
• Tracks usage trends: It provides insights into the substance use pattern over time, instead of just recent consumption.

Limitations:

• Incapable of detecting recent consumption: Drugs typically require 5-7 days to become evident in hair.
• Price: Hair drug tests tend to be more costly than alternative drug testing approaches.
• Result disparities: Attributes such as hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis involves 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. 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.
