Hair Follicle Drug Testing - Neillsville, WI

What it is, How it works

Hair analysis has emerged as an efficacious method for identifying drug and alcohol consumption. Hair strands encapsulate long-term consumption biomarkers within their growing fibers. When sourced from the scalp, hair can extend a detection range to nearly 3 months for both alcohol and other substances. Hair samples are straightforward to collect, resistant to tampering, and simple to dispatch.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp provides 100mg, which is optimal for both initial screening and validation. For tests such as EtG and more extensive panels beyond 10 markers, a 150mg sample is advisable. We suggest using a jeweler's scale for weighing the sample. In cases where scalp hair isn't available, an equivalent volume of body hair can be used. "Head hair" specifically refers to hair on the scalp, while "body hair" encompasses all other types (e.g., facial, axillary, etc.).

Process Overview

There are four principal stages in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial processing within a lab's network. This step includes confirming that the sample was secured and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entries that weren’t managed by an electronic tracking system.

Screening conducts a preliminary and rapid inspection for drug traces. While effective for excluding drug use in most samples, any positive screening result necessitates confirmation for legal admissibility. Presumptive positive samples from Screening require subsequent confirmation.

When a sample tests presumptively positive at the Screening phase, additional hair is extracted from the initial set and prepped for Extraction. In this segment, trace drugs are isolated from the hair at lower concentrations compared to other methods (e.g., urine or oral fluids), underscoring why hair testing is a challenging process.

The Confirmation phase for any positive findings utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a cleansing procedure prior to Confirmation when needed. The entire lab procedure, from Accessioning through Confirmation, is scrutinized according to the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can identify drug consumption up to 90 days, unlike urine tests which offer a shorter detection duration.
• Lower likelihood of manipulation: Hair drug tests are challenging to compromise, increasing result reliability.
• Offers historical usage data: It can reveal a pattern of substance use over time, not solely recent use.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug assays generally incur higher costs compared to other testing approaches.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", the examination targets the hair strand itself and not the follicle beneath the scalp.

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.
