Hair Follicle Drug Testing - Grand Marsh, WI

What it is, How it works

The effectiveness of hair testing for identifying drug and alcohol consumption is widely acknowledged. By capturing biomarkers in the fibers of a growing strand, hair offers a prolonged history of alcohol and drug presence. When taken close to the scalp, these samples can cover a detection period of up to roughly three months for both alcohol and drugs. Hair is easy to collect, hard to tamper with, and convenient to transport.

A 1.5-inch segment involving around 200 strands of hair (roughly matching a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a sample of 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. Should scalp hair not be available, an equivalent portion of body hair can be used. Here, head hair refers solely to scalp hair, while body hair includes all other types (face, underarm, etc.).

Process Overview

The laboratory procedure for processing a drug test outcome involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial steps of integrating a sample into a lab's system. This covers confirming the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any further data not included in an electronic chain of custody system.

Screening offers a prompt evaluation for drugs of concern. Despite being a cost-effective option for negating drug use in most samples, a positive result necessitates confirmation to be valid in legal settings. Samples indicating a presumptive positive in Screening require subsequent verification.

In scenarios where a sample shows a presumptive positive during Screening, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are obtained from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo necessary washing before confirmation. The complete lab process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a limited detection period.
• Hard to manipulate: Cheating on a hair drug test is exceedingly difficult, ensuring more reliable results.
• Historical insight: It offers an overview of drug use patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Hair drug tests typically incur higher costs compared to other testing approaches.
• Variability in results: Elements such as hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", these tests examine the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Grand Marsh, WI, the former stands out due to its superior detection capabilities and accuracy. Hair testing detects a broader spectrum of substances with higher reliability, making it a preferred choice for employers and organizations seeking comprehensive testing solutions.

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.
