Hair Follicle Drug Testing - Eagar, AZ

What it is, How it works

Hair analysis is now regarded as a robust method for identifying drug and alcohol consumption. By embedding markers in the fibers of the hair shaft, hair can reveal prolonged usage of alcohol and other substances. When cut close to the scalp, it can offer up to a three-month detection period for these substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A hair segment of 1.5 inches, comprising roughly 200 strands (comparable to a #2 pencil), closest to the scalp typically yields 100mg, making it the perfect sample for both screening and confirmation. For EtG, additional tests, or analyses beyond 10 panels, a 150mg sample is advised. It's suggested to weigh the hair on a jeweler’s scale. In cases where scalp hair is unavailable, a comparable quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (including facial and axillary).

Process Overview

The lab processing of drug test results is divided into four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial intake of a sample into the lab’s system. This step includes confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data recording absent from an electronic custody system.

Screening entails a preliminary evaluation for drugs of abuse. Though Screening is an economical approach to exclude drug use in most samples, a screen showing a positive result needs to be verified for court admissibility. Any samples with presumptive positive results in Screening require subsequent confirmation.

If a presumptive positive arises during the Screening phase, additional hair is extracted from the original sample and processed for Extraction. During this phase, drugs are withdrawn from hair at markedly lower concentrations compared to other methods (like urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation as necessary. The entire lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests, which have a shorter detection span.
• Challenging to deceive: It's exceedingly difficult to falsify a hair drug test, which enhances the accuracy of results.
• Offers historical insight: It can illustrate a drug use pattern over a time frame, rather than just recent consumption.

Limitations:

• Unable to identify recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more compared to other drug testing techniques.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Although frequently called "hair follicle tests", the analysis targets 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. 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.
