Hair Follicle Drug Testing - Elkin, NC

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol usage. Hair retains a detailed record of alcohol and drugs by embedding biomarkers within the hair strand as it grows. When taken near the scalp, hair can reveal substance use for around a three-month duration. This method is straightforward to collect, relatively tamper-resistant, and simple to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, considered the optimal amount for both screening and confirmation. For EtG, additional tests, and tests over 10 panels, a 150mg sample is suggested. It is advisable to measure the sample using a jeweler’s scale. In situations where scalp hair is not obtainable, a similar quantity of body hair is an acceptable alternative. "Head hair" pertains specifically to scalp hair, whereas "body hair" encompasses all other types such as facial and axillary hair.

Process Overview

The laboratory processing of drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial phase of entering a specimen into the lab system. This step ensures that the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data input not captured by an electronic chain of custody.

Screening offers a preliminary and efficient method to check for drug abuse. While a positive Screening outcome is useful, it must be verified to be legally admissible, necessitating a confirmation for any presumptive positives identified in Screening.

In the event a sample shows a presumptive positive result during Screening, additional hair is extracted from the original sample for preparation in the Extraction phase. In Extraction, drugs are removed from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging technique to administer.

To confirm any positive results from screening, GC/MS, GC/MS/MS, or LC/MS/MS methods are used. All samples that are tentatively positive undergo washing before confirmation as required. The comprehensive laboratory workflow from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation specifications.

Advantages of hair drug testing:

• Significant timeframe for detection: Hair tests can identify drug use spanning 90 days, offering a longer window than urine tests.
• Hard to manipulate: The difficulty in tampering with a hair test results in higher accuracy.
• Reflects usage trends: It provides insight into drug usage over time rather than solely recent use.

Limitations:

• Inability to detect recent usage: Drugs become evident in hair only after roughly 5-7 days.
• Expense: Hair testing generally incurs higher costs than other drug testing approaches.
• Result variability: Hair color and individual hair growth differences can influence metabolite concentrations found in hair.

Note: Despite being commonly referred to as "hair follicle tests", the analysis is carried out on 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. 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
