Hair Follicle Drug Testing - Belle, MO

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of substance use by capturing biomarkers within its fibers as it grows. When collected near the scalp, hair can reveal drug and alcohol use history for as long as three months. It is easy to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch piece of hair approximately equivalent to the thickness of a #2 pencil, taken close to the scalp, weighs around 100mg, which is ideal for both screening and confirmation tests. For EtG, additional tests, or panels beyond 10, a 150mg sample is advised. It's best to measure the specimen's weight with a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be used. By scalp hair, we refer exclusively to head hair. Other types of hair (facial, armpit, etc.) are considered body hair.

Process Overview

Four primary steps define the laboratory process for a drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially entered into the laboratory system, which involves confirming that the sample is properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and performing any additional manual data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drug abuse. Although screening efficiently eliminates drug use in most samples, any positive result needs confirmation to be legally admissible. Samples that test presumptively positive during Screening require further confirmation.

In the case of a presumptive positive during Screening, more hair is taken from the initial sample for Extraction. Here, drugs are separated from hair at concentrations much lower than other methods, such as urine or oral fluid testing, making hair drug screening the most challenging method to conduct.

Confirmation of positive screening results involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation, if needed. The entire procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair tests can reveal drug use for up to three months, unlike urine tests with shorter detection windows.
• Difficult to falsify: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Chronological usage data: It offers insights into a long-term drug use pattern rather than recent consumption only.

Limitations:

• Cannot detect recent intake: Drugs become traceable in hair within five to seven days.
• Expense: Hair drug testing often costs more compared to other methods.
• Result variability: Drug metabolite concentration in hair can be influenced by hair color and individual growth rates.

Note: Often called "hair follicle tests," these tests actually analyze the hair strand rather than the follicle located under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Belle, MO, hair follicle drug testing is superior to traditional urine tests. With improved detection accuracy and reliability, hair testing gives a more comprehensive picture of substance use. While urine tests can detect recent drug use, hair tests offer a clearer, longer-term view, making them a better alternative for thorough assessments.

Extended Detection Window

Hair follicle testing in Belle, MO stands out due to its extended detection window. Unlike other methods, it captures drug use for up to 90 days, offering employers a comprehensive insight into an individual's substance history. This long-term detection capability is invaluable for employers seeking a detailed understanding of employees' habits.

Tamper-Resistant Testing Method

In Belle, MO, the tamper-resistant nature of hair follicle tests makes them an excellent choice. By significantly reducing sample adulteration risks, these tests yield reliable and verified outcomes. This integrity in results ensures authenticity and builds trust in the testing method.

Convenient Nationwide Locations

Belle, MO offers convenient access to testing facilities nationwide, making it simple for individuals to complete necessary screenings. These widespread locations enable quick, hassle-free access, providing a seamless testing experience that fits any schedule.

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.
