Hair Follicle Drug Testing - Van Horne, IA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the developing hair fibers, hair offers a comprehensive long-term account of drug usage. When obtained near the scalp, hair provides a detection timeframe of up to roughly three months for alcohol and other substances. The collection of hair is straightforward, relatively tamper-resistant, and simple to transport.

A sample from the scalp measuring 1.5 inches and containing roughly 200 hair strands (around the thickness of a #2 pencil) yields 100mg, which is the optimal quantity for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a sample weighing 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. If head hair isn't obtainable, a similar volume of body hair can be collected. References to head hair pertain exclusively to hair from the scalp. Body hair encompasses all other hair varieties (facial, underarm, etc.).

Process Overview

The laboratory process for drug test evaluation primarily includes the stages of Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about integrating the sample into the lab's system initially. This stage ensures the sample's seal and shipment integrity, assigns a Laboratory Accessioning Number (LAN), and fills in any required data not submitted through an electronic custody chain.

Screening acts as a preliminary scan for drug abuse indicators. While it efficiently discounts drug consumption in most cases, positive results from Screening necessitate Confirmation for legal acceptance. Presumptively positive samples in Screening demand further validation.

In cases of presumptive positivity in Screening, additional hair is taken from the sample and readied for Extraction. This phase involves extracting drugs from the hair at lower concentrations compared to other methods like urine or oral fluid, making hair drug screening notably complex.

Positive screening results go through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a cleansing before Confirmation as required. Every laboratory step from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair guidelines and follows ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection span: Hair assessments identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Test integrity: The challenge of falsifying hair tests results in higher accuracy.
• Usage patterns: It charts drug consumption over time instead of merely recent usage.

Limitations:

• Ineffective for recent use: Drugs become traceable in hair only after 5-7 days.
• Expense: Typically, hair tests are pricier than alternative drug testing methodologies.
• Result variability: Hair color differences and individual growth variations might influence metabolite concentration in hair.

Note: Despite being termed "hair follicle tests", these tests analyze the hair strand itself rather than the scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

Why Choose Hair Follicle Testing in Van Horne, IA?
For more dependable results, hair follicle testing surpasses traditional urine tests. The key advantage lies in superior detection accuracy and reliability.

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.
