Hair Follicle Drug Testing - Humboldt, IL

What it is, How it works

Hair testing is highly regarded as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged history of substances by encapsulating biomarkers in the fibers of the hair as it grows. A sample taken near the scalp can indicate alcohol and other drugs use for roughly a 3-month period. Hair collection is straightforward, tough to tamper with, and convenient to transport.

A 1.5-inch section of about 200 hair strands (approximately the width of a #2 pencil) located nearest the scalp is necessary for acquiring 100mg of hair, which is ideal for screening and verification. For EtG, additional tests, and/or other panels beyond 10, a sampling of 150mg is recommended. We advise using a jeweler’s scale for weighing. If scalp hair is unavailable, an equal quantity of body hair can be substituted. Head hair denotes scalp hair solely, while body hair includes all other hair varieties (facial, axillary, etc.).

Process Overview

There are four primary steps in processing a lab drug test result, which are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a sample into the lab's system. It ensures the sample was sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data input not included via an electronic chain of custody.

Screening is a preliminary quick test for substances of abuse. While it is a cost-efficient method to eliminate drug usage for the majority of samples, a positive screen must be verified for legal admissibility. Any samples with presumptive positives require a confirmatory test.

When a sample tests presumptively positive in Screening, extra hair is extracted from the original sample and processed for Extraction. Here, substances are extracted from the hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.

Confirmation of any positive screen is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives are washed if necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can trace drug use for as long as 90 days, unlike urine tests which offer shorter time frames.
• Difficult to falsify: It is notably hard to falsify a hair drug test, resulting in more accurate outcomes.
• Chronicles historical use: Offers a timeline of drug use over an extended period, not merely recent consumption.

Limitations:

• Inability to detect recent use: Approximately 5-7 days are required for drugs to be discernible in hair.
• Expense: Generally, hair drug tests are pricier than other testing techniques.
• Variability in results: Elements like hair color and unique hair growth differences can influence the levels of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the test analyzes the hair strand, 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.
