Hair Follicle Drug Testing - Apple Grove, VA

What it is, How it works

Hair testing is now recognized as a robust method for detecting substance use. Hair captures a comprehensive record of alcohol and drug consumption by embedding biomarkers within the growing hair strands. When collected near the scalp, it offers up to a 90-day window for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A hair sample of 1.5 inches, about the width of a #2 pencil, should consist of approximately 200 strands, providing 100mg of hair, ideal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg is advisable. We advise using a jeweler’s scale for measuring the specimen. Should scalp hair be insufficient, an equivalent amount of body hair may be used. Reference to head hair pertains exclusively to scalp hair, while body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

There are four key steps in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a lab’s system. This step involves checking if the sample is sealed and shipped appropriately, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not provided by an electronic chain of custody.

Screening is a preliminary check for drugs of abuse. Although it is a cost-effective method to dismiss drug usage in most cases, a positive result in Screening must be confirmed to be valid in legal settings. Presumptive positive samples in Screening require further confirmation.

Should a sample return a presumptively positive result in Screening, additional hair is taken from the original specimen for Extraction. In this phase, drugs are isolated from hair at much lower concentrations compared to methodologies like urine or oral fluid testing, making hair drug screening a more complex process.

Positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The full lab process from Accessioning to Confirmation is subjected to review under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests offer a 90-day detection period, unlike urine tests with shorter durations.
• Difficult to deceive: Hair drug tests are challenging to manipulate, enhancing accuracy.
• Offers historical insight: It provides a timeline of drug use over months, rather than only recent consumption.

Limitations:

• Unable to detect recent usage: Drugs take 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Frequently termed "hair follicle tests", this test examines hair strands, not the follicles 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.
