Hair Follicle Drug Testing - Villa Pancho, TX

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It captures biomarkers within the hair strand fibers, offering an extended history of substance use. When gathered near the scalp, hair can reveal a detection window of up to roughly 3 months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to send.

A 1.5-inch portion of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal sample size for tests. For EtG, additional tests, or for panels exceeding 10, a sample of 150mg is suggested. Using a jeweler’s scale to measure the specimen is advised. If scalp hair is not an option, a comparable quantity of body hair can be collected. References to head hair indicate scalp hair solely. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into the laboratory system. This step checks that the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not included by an electronic chain of custody system.

Screening provides a preliminary check for illicit substances. While it offers an affordable way to dismiss drug use in most cases, a positive screening must be validated to be legally acceptable. Samples with a presumptive positive result in Screening need to undergo additional confirmation.

Should a sample yield a presumptive positive in Screening, extra hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are pulled from hair at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing a complex methodology to execute.

Confirmation of any positive screen is done using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo a wash before confirmation as required. The full lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and 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 shorter detection period.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Shows usage patterns: It indicates drug use patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs start becoming detectable in hair roughly 5-7 days post-consumption.
• Cost implications: Generally, hair drug tests are pricier than other drug testing techniques.
• Result variability: Variations like hair color and individual hair growth rates can impact drug metabolite concentrations in hair.

Note: Despite being called "hair follicle tests," the test analyzes the hair strand itself, not the follicle under 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.
