Hair Follicle Drug Testing - Saint David, IL

What it is, How it works

Hair analysis has gained prominence as an effective means to identify drug and alcohol consumption. It provides a long-term record by embedding biomarkers within the follicles of the growing strand. By obtaining samples adjacent to the scalp, it grants up to a 3-month detection span for substances. Collecting hair is straightforward, less prone to tampering, and convenient to transport.

A 1.5-inch segment comprising around 200 strands (roughly equivalent to the circumference of a #2 pencil) from near the scalp yields 100mg, optimal for evaluating and verification. For EtG, additional tests, and panels exceeding ten, the suggestion is 150mg. It's advisable to measure the sample using a jeweler’s scale. If scalp samples are unavailable, a comparable quantity of body hair is an alternative. Scalp references imply head hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test encompasses four vital phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about initiating sample processing within a lab's framework. This encompasses ensuring proper sealing and dispatch of the sample, allocating a random Laboratory Accessioning Number (LAN), and fulfilling any additional data entries that aren't covered by an electronic chain of custody system.

Screening offers an expeditious check for substance abuse. It’s a cost-efficient means to exclude drug use in most cases, but a positive requires verification for court admissibility. Samples flagged as presumptive positives necessitate secondary confirmation.

Upon a presumptive positive in Screening, additional hair is procured from the original set for Extraction, where drugs are extracted at significantly lower concentrations than other methods (like urine or oral fluid), explaining the intricate nature of hair drug assays.

Confirming any positive results occurs through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation if necessary. The complete procedure from Accessioning to Confirmation is critically evaluated under both the CAP's Hair categorization and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair assays can track drug usage for up to 90 days, surpassing urine tests with a shorter detection period.
• Resilience against evasion: Cheating a hair drug test is challenging, enhancing the reliability of results.
• Chronicles usage: It delineates a pattern of substance use over an extended time frame, unlike recent usage detection.

Limitations:

• Inability to spot recent consumption: Detectability in hair needs 5-7 days post-consumption.
• Expense: Hair assays usually cost more than other drug detection approaches.
• Result discrepancies: Variables like hair color and growth variances can modulate drug metabolite concentrations.

Note: Despite being termed "hair follicle tests", the examination targets the hair strand, not the underlying follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers an obvious edge over urine analysis when it comes to accuracy and reliability in Saint David, IL.
While traditional urine tests can detect recent use, hair testing reveals a more extended usage history, reflecting substance patterns over time. Companies benefit from unbiased and trustworthy results, improving their decision-making on potential hires.

Extended Detection Window

With a detection proficiency stretching up to 90 days, hair follicle testing in Saint David, IL, unveils an individual's substance use many weeks beyond that of urine tests.

• This extensive detection window provides companies a clearer understanding of an applicant's or employee's drug history.
• Employers obtain a more holistic view, contributing to better-informed decisions.

Tamper-Resistant Testing Method

One primary advantage of opting for hair follicle tests in Saint David, IL, is their remarkable resistance to tampering.

Unlike urine tests, which may be susceptible to adulteration or dilution, the integrity of hair samples makes them almost impossible to alter. This reliability provides unquestionable results, essential for entities requiring definitive substance use histories.

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.
