Hair Follicle Drug Testing - Isla Vista, CA

What it is, How it works

Hair analysis is recognized as a significant method for identifying drug and alcohol consumption. The fibers in growing hair strands encapsulate biomarkers, offering an extended timeline of substance use. When sourced near the scalp, hair can reveal substance exposure up to a 3-month period for alcohol and other substances. Collecting hair is straightforward, relatively tamper-resistant, and easily transportable.

A 1.5-inch hair segment consisting of roughly 200 strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for testing and validation. For EtG, supplementary testing, and/or analyses surpassing 10 panels, it's advisable to procure 150mg of the sample. We suggest measuring the sample using a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be taken. When discussing head hair, we mean only scalp hair. Body hair pertains to any other hair types (beard, underarm, etc.).

Process Overview

The core phases in the lab procedure of drug result processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial input of a sample into a lab's system. This step ensures the sample was correctly sealed and sent, allocates a random LAN (Laboratory Accessioning Number), and finishes any necessary data input missing from an electronic custody trail.

Screening entails a swift preliminary test for illicit substances. While Screening economically excludes drug use in most samples, a positive screen demands verification for court acceptance. Samples showing presumptive positives in Screening necessitate further confirmation.

When a sample shows presumptive positivity during Screening, additional hair from the initial sample is utilized for Extraction. At this stage, drugs are isolated from hair at notably lower levels than seen in other techniques (e.g., urine or oral fluids), rendering hair drug screening a highly challenging practice.

Confirmation of a positive screen is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are washed before verification as required. The complete lab sequence from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection span: Hair drug evaluations can identify drug use up to 90 days, contrasting with urine evaluations which offer a shorter detection period.
• Hard to deceive: Cheating a hair drug assessment is challenging, enhancing result reliability.
• Offers historical insights: It reveals a substance usage trend over a timeframe, not only recent use.

Limitations:

• Cannot spot recent intake: It requires roughly 5-7 days for substances to appear in hair.
• Expense: Hair drug assessments tend to be pricier than other testing methods.
• Result inconsistencies: Elements such as hair pigment and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the examination involves 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.
