Hair Follicle Drug Testing - Eldridge, FL

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol usage. Hair offers an extensive timeline of substance intake by encapsulating biomarkers within the strands as they grow. When collected near the scalp, hair can indicate drug or alcohol presence for up to three months. It's easy to collect, not easy to tamper with, and simple to transport.

A sample of 1.5 inches in length, consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is optimal for analysis. For more detailed testing, such as with EtG, additional panels, or tests exceeding 10 panels, 150mg is advisable. It's best to weigh samples using a jeweler’s scale. If scalp hair isn't accessible, a comparable amount from the body may be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of test results consists of four core steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, samples are initially processed into the lab's system, including verification of proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry not available through electronic chains of custody.

Screening is a preliminary assessment aimed at detecting drug misuse. Although cost-effective for a majority of samples, a positive result in Screening needs confirmation for legal use. Samples that are initially presumptive positive require further confirmation.

For presumptive positives during Screening, additional hair is obtained from the initial sample for Extraction. At this stage, drugs are extracted at a much lower concentration than other methods (like urine or oral fluid), making hair drug testing a complex process.

Any positive Screening results must be confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are cleansed before confirmation as necessary. Every laboratory step from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use spanning up to 90 days, whereas urine tests cover a shorter duration.
• Cheating is minimal: This testing method is hard to compromise, ensuring accurate results.
• Shows usage pattern over time: Provides a history of drug consumption, unlike other methods that show only recent use.

Limitations:

• Recent use undetectable: Drugs only become detectable in hair after roughly 5-7 days.
• Expense: Hair drug testing tends to be costlier than alternative testing methods.
• Variability in outcomes: Factors like hair color and individual growth differences can influence metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", this refers to testing the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Eldridge, FL, hair follicle testing offers distinct advantages over traditional urine tests. Detection accuracy is a standout feature, delivering more reliable results.

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.
