Hair Follicle Drug Testing - Wilsonville, IL

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol usage. Hair captures biomarkers within the strands of growing hair, offering an extended history of alcohol and drug use. Samples taken near the scalp can yield a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, not easily tampered with, and simple to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. It's best to weigh the sample on a jeweler’s scale. If head hair is unavailable, an equivalent quantity of body hair can be used. When discussing head hair, it specifically refers to scalp hair. Body hair includes all other types such as facial and axillary hair, among others.

Process Overview

Four primary steps are involved in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a laboratory’s system. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data entry not covered by an electronic chain of custody system.

Screening swiftly checks for drug abuse. While Screening is a cost-effective approach to eliminate drug use in most samples, a positive result needs confirmation for legal admissibility. Samples showing presumptive positive results in Screening require further confirmation.

With presumptive positive samples in the Screening stage, additional hair is prepared for Extraction. At this stage, drugs are extracted from hair at much lower concentrations compared to techniques like urine or oral fluid analysis, making hair drug screening the most challenging method.

Confirming any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests that have a shorter timeframe.
• Hard to falsify: It is extremely challenging to cheat a hair drug test, ensuring more reliable results.
• Historical insight: Allows for a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to show recent use: Approximately 5-7 days are needed before drugs are detectable in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Even though termed "hair follicle tests", the test examines the hair strand rather than 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.
