Hair Follicle Drug Testing - Gillett, WI

What it is, How it works

Hair analysis is now acknowledged as an effective method for detecting alcohol and drug usage. Hair serves as a chronic marker for substance intake by preserving biomarkers within the strands as they grow. When cut close to the scalp, a hair sample can offer a drug and alcohol detection span of nearly three months. Collection is straightforward, tampering is challenging, and transportation is hassle-free.

A sample measuring 1.5 inches comprised of around 200 strands (equivalent to the thickness of a #2 pencil) collected near the scalp provides 100mg, which is optimal for testing and validation. For screenings such as EtG, additional panels exceeding ten, a 150mg sample is advisable. We suggest checking the specimen weight with a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair might be utilized. When we mention head hair, this pertains solely to scalp hair. Body hair encompasses all other types like facial and underarm hair.

Process Overview

The drug testing process in a lab comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial intake of a sample into the lab's protocol, ensuring correct sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data in the absence of an electronic chain of custody system.

Screening provides a preliminary assessment for substance abuse. While it is a cost-efficient method to exclude drug use in most cases, any positive result from Screening must be verified for legal acceptance. Presumptively positive samples require subsequent verification.

Should a Screening test yield a presumptive positive, additional hair is extracted from the sample for the Extraction phase. Here, drugs are isolated at concentrations far lower compared to other methods such as urine or oral fluid, highlighting the complexity of hair analysis.

Verification of any positive result from Screening is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. Samples that are deemed presumptively positive go through a cleansing process before verification as necessary. From Accessioning to Confirmation, the entire procedure is overseen under both the CAP (College of American Pathologists) Hair guidelines and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection range: Hair testing can trace drug usage for as long as 90 days, unlike urine tests which have a shorter range.
• Hard to deceive: Counterfeiting a hair drug test is notably difficult, hence producing more reliable results.
• Reflects usage history: It reveals a history of substance intake across a timeframe, not merely recent usage.

Limitations:

• Inability to detect recent intake: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variability: Variables like hair color and individual hair growth patterns can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand and not the sub-scalp follicle.

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.
