Hair Follicle Drug Testing - Winona Lake, IN

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The fibers of a growing hair strand can trap biomarkers, offering a long-term record of substance use. When obtained near the scalp, hair provides a detection window of up to approximately three months for substances like alcohol. Collection is straightforward, tampering is somewhat challenging, and shipping is uncomplicated.

A sample of 1.5 inches consisting of about 200 hair strands, roughly the size of a #2 pencil, taken closest to the scalp, equates to 100mg of hair, which is the optimal sample amount for both screening and confirming results. For testing such as EtG, additional substances, or tests exceeding 10 panels, 150mg of hair is advised. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair is not available, a similar amount of body hair can be utilized. "Head hair" specifically refers to scalp hair only, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process revolves around four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into the lab's system. It entails confirming that the sample is sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any further data entry not available through an electronic chain of custody mechanism.

Screening encompasses a preliminary, swift check for illicit substances. While Screening serves as an economical method for dismissing drug use in most cases, any positive result necessitates confirmation for legal admissibility. Any samples that yield a presumptive positive during Screening require secondary confirmation.

When a Screening stage sample shows a presumptive positive, additional hair is sourced from the initial sample for the Extraction phase. In this stage, drug detection is performed at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug screening the most challenging to conduct.

Confirmation of any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are appropriately washed before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, undergoes review 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 testing can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Tampering difficulty: Cheating a hair drug test is notably hard, enhancing result reliability.
• Historical usage data: It provides insight into patterns of substance use over extended periods, not just recent use.

Limitations:

• Inability to identify recent use: Approximately 5-7 days are required for substances to become detectable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to other testing alternatives.
• Result variability: Attributes such as hair color and personal variations in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly termed "hair follicle tests," the procedure actually examines the hair strand 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.
