Hair Follicle Drug Testing - Legend Lake, WI

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair archives a prolonged timeline of substance intake by embedding biomarkers in the structure of the advancing hair strand. When harvested near the scalp, hair can reveal a detection window of up to roughly three months for alcohol and other drugs. Hair is straightforward to gather, less vulnerable to tampering, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (similar in diameter to a #2 pencil) nearest to the scalp yields 100mg, which is the ideal sample size for testing and verification. For EtG, additional analyses, or tests beyond 10 panels, it’s advisable to use 150mg of the sample. We recommend using a jeweler’s scale for weighing. If scalp hair is not present, an equivalent quantity of body hair may be taken. Terms such as head hair refer solely to scalp hair, whereas body hair encompasses all other types like facial or axillary hair.

Process Overview

The procedure for laboratory processing of a drug test result entails four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning forms the initial phase of incorporating a sample into the lab's system. The activities here include confirming that the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody platform.

Screening offers a preliminary assessment for substance abuse. While it provides a budget-friendly mode to discount drug usage for most samples, any positive findings in Screening must be substantiated to be court-admissible. Samples flagged as presumptive positives in Screening need further corroboration.

When a sample exhibits presumptive positivity in the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this process, drugs are isolated from hair at much lower concentrations than in alternate methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging techniques to implement.

Verification of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleansed before confirmation if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug consumption for up to 90 days, whereas urine assessments have a briefer detection timeframe.
• Hard to manipulate: It is notably challenging to deceive a hair drug test, which enhances the credibility of results.
• Delivers historical context: It can offer a timeline of drug usage, not limited to recent intake.

Limitations:

• Cannot spot recent consumption: Approximately 5-7 days are needed before drugs become traceable in hair.
• Expense: Hair drug tests typically incur higher costs than other modalities of drug testing.
• Differences in results: Elements such as hair color and individual hair growth rates can influence the drug metabolite levels in hair.

Note: Despite often being called "hair follicle tests", the examination focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The advantages of hair follicle testing over traditional urine tests in Legend Lake, WI, are significant. Unlike urine tests that detect recent drug use, hair tests provide a comprehensive overview reaching up to 90 days. This superior detection period means hair tests are more reliable and less susceptible to tampering, making them a preferred choice for employers enforcing strict drug policies.

Extended Detection Window

The extended detection window of hair follicle testing in Legend Lake, WI, is a key benefit for many employers. By analyzing hair samples, they can uncover drug use histories up to three months back, offering comprehensive insights. This allows for better-informed decisions regarding current or potential employees, ensuring a safer work environment.

Tamper-Resistant Testing Method

Hair follicle testing in Legend Lake, WI, provides a tamper-resistant method to check for substance use. Due to the nature of the sample collection process and the biological composition of hair, the risk of adulteration is greatly reduced. This results in more reliable and credible outcomes, reaffirming the trust in this method.

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.
