Hair Follicle Drug Testing - Lancaster, WI

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term record of substance use by storing biomarkers within the strands as the hair grows. When a sample is cut near the scalp, it can provide up to a three-month detection range for substances. The collection process is straightforward, the samples are hard to tamper with, and they are easy to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (around the thickness of a #2 pencil), cut closest to the scalp, yields 100mg of hair—the optimal amount for both initial analysis and confirmation. For tests including EtG, additional analytes, or those exceeding ten panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for accurate weighing. In cases where scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair includes all other types, such as facial or axillary hair.

Process Overview

The drug test result processing in a laboratory includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the introduction of a sample into the laboratory's system. This step ensures the sample's proper sealing and transit and assigns a unique LAN (Laboratory Accessioning Number), while also completing any missing data not captured by an electronic chain of custody.

During Screening, a preliminary investigation for drug use is conducted. Although Screening offers an economical way to exclude drug use in most cases, any positive results obtained must be verified to be legally valid. Samples that test presumptively positive in this stage require further confirmation.

Positive results from Screening involve pulling additional hair from the original sample and preparing it for Extraction. In this phase, substances are isolated from the hair, though at a lower density than found in other testing methods, like urine or oral fluid, making hair drug testing particularly challenging.

Confirmation of positive Screening results is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives undergo washing before confirmation if necessary. The entire process, from Accessioning to Confirmation, is conducted under scrutiny following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair drug tests detect the presence of drugs for up to 90 days.
• Reduced chance of tampering: Cheating is notably difficult with hair drug tests, enhancing result reliability.
• Insightful historical data: These tests can reveal drug usage trends over time, beyond just recent consumption.

Limitations:

• Not ideal for recent detection: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs compared to other methods.
• Result variability: Factors like hair color and individual growth patterns can influence drug metabolite concentrations.

Note: Commonly called "hair follicle tests," the analysis focuses on the hair strand itself, not the follicle beneath the skin surface.

Why Hair Follicle Testing Beats Urine Testing

When it comes to choosing a drug test in Lancaster, WI, hair follicle testing eclipses urine testing due to its superior accuracy and reliability. Hair tests boast a longer detection window, capturing up to 90 days of drug use history, while urine tests fall short, particularly for extended usage timelines. This ensures employers receive a comprehensive view and make informed decisions.

Extended Detection Window

In Lancaster, WI, hair follicle testing offers a significant benefit with its extended detection window. Unlike traditional tests, hair analysis captures drug use over a longer period—up to 90 days.

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.
