Hair Follicle Drug Testing - Lincoln Park, GA

What it is, How it works

Hair analysis has emerged as an effective methodology for identifying substance and alcohol consumption. Hair retains long-term consumption markers within the fibers of the hair strand as it grows. When taken from near the scalp, hair can indicate use of alcohol and drugs up to a roughly 3-month duration. The collection of hair is straightforward, challenging to tamper with, and simple to transport.

A segment measuring 1.5 inches consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, an optimal quantity for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a sample of 150mg is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. In cases where scalp hair is not present, a similar measure of body hair can be collected. "Head hair" specifically refers to hair from the scalp, while "body hair" includes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory drug testing result process involves four major stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially integrated into a lab’s system. This encompasses ensuring the sample's seal and shipment were correct, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent in an electronic chain of custody.

Screening executes a preliminary and swift analysis for substances of abuse. Although it’s a budget-friendly way to exclude drug usage for most samples, a positive outcome in Screening requires verification to hold up in legal settings. Every sample showing a presumptive positive in Screening mandates further confirmation.

Should a sample display presumptive positivity during Screening, additional hair is extracted from the original sample to undergo Extraction. In this process, substances are isolated from the hair at concentrations lower than those found in other methods (e.g., urine or oral fluid), rendering hair analysis the most challenging method to execute.

Confirmation of any positive screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing as necessary before confirmation. The comprehensive laboratory procedure from Accessioning through Confirmation is assessed under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug consumption for a period reaching 90 days, unlike urine tests with shorter detection spans.
• Cheating is challenging: The difficulty in cheating hair drug tests results in higher accuracy.
• Displays historical usage: It can show a pattern of substance use over time, not merely recent usage.

Limitations:

• Cannot identify recent intake: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically more costly than other testing methodologies.
• Result variability: Elements such as hair color and individual growth differences can impact the level of drug metabolites in hair.

Note: Despite often being called "hair follicle tests", the examination 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.
