Hair Follicle Drug Testing - Mcgonigle, OH

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive record of substance use by encasing biomarkers within the fibers of the growing hair shaft. When gathered near the scalp, hair offers up to an approximately 3-month window for detecting alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch segment containing around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a specimen weight of 150mg is advisable. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be collected. The term head hair exclusively refers to scalp hair. In contrast, body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for processing a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's system. This step involves ensuring the sample was securely sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry not covered by an electronic chain of custody system.

Screening performs a preliminary assessment for drugs of abuse. While cost-efficient for eliminating drug use in most samples, a positive screen requires further confirmation to be court-admissible. Samples that are presumptively positive in Screening necessitate additional confirmation.

Upon a presumptive positive result in the Screening phase, extra hair is extracted from the primary specimen and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Confirmation of positively screened results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. Every phase from Accessioning to Confirmation aims for stringent compliance under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests detect drug usage for up to 90 days, unlike the shorter window of urine tests.
• High resistance to tampering: Cheating a hair drug test is exceedingly challenging, enhancing result integrity.
• Chronological data: It reveals a usage pattern over time, rather than recent usage alone.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair roughly 5-7 days after consumption.
• Expense: Hair drug tests are usually costlier than other drug testing methods.
• Result variability: Factors like hair color and individual growth differences can alter drug metabolite concentration in hair.

Note: The commonly used term "hair follicle tests" is inaccurate; the analysis targets 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.
