Hair Follicle Drug Testing - Harcuvar, AZ

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying the consumption of drugs and alcohol. Hair strands retain biomarkers within their fibers over time, providing a prolonged account of drug and alcohol usage. When hair gathered close to the scalp is used, it can reveal substance consumption within approximately a 3-month period. The collection process for hair is straightforward, it's relatively tamper-resistant, and it's simple to transport.

A hair sample of 1.5 inches containing around 200 hairs (similar in size to a #2 pencil) near the scalp provides an optimal 100mg sample for both screening and confirmation. For enhanced testing such as EtG additions and/or tests beyond the 10-panel level, a 150mg sample is advised. For precise measurement, we suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an alternative can be an equivalent amount of body hair. When mentioning head hair, we are referring specifically to scalp hair. Body hair includes other types such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial procedure where a sample is entered into the lab’s system. This step ensures the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not managed by an electronic custody system.

Screening conducts an initial rapid test for drug presence. While cost-efficient and effective at ruling out drug usage in most cases, a positive screening requires a follow-up for court admissibility. Any presumptive positive results in Screening necessitate further confirmation.

For samples that show presumptive positives during Screening, additional hair is taken from the primary sample for Extraction. This stage involves removing drugs from the hair at concentrations lower than those required in other methodologies (such as urine or oral fluid tests), which underscores the complexity of performing hair drug testing.

Positive screening confirmation is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo washing prior to confirmation if necessary. From Accessioning to Confirmation, the entire laboratory process aligns with the CAP (College of American Pathologists) Hair standards and maintains compliance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug usage up to 90 days, unlike urine tests with shorter timelines.
• Challenging to falsify: The difficulty of cheating a hair test enhances the accuracy of its results.
• Tracks historical patterns: It can show longitudinal drug usage patterns, not just recent consumption.

Limitations:

• Incapable of recent detection: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Hair color and unique growth rates can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the procedure analyzes the hair strand and not the roots 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.
