Hair Follicle Drug Testing - Panaca, NV

What it is, How it works

Hair analysis has emerged as a robust approach for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug presence by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair offers a detection range that extends up to roughly 90 days for both alcohol and drugs. It’s straightforward to collect, relatively challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (approximating the girth of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal size for both screening and confirmation. For EtG, supplementary tests, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. We propose weighing the sample using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair may be gathered. When denoting head hair, we exclusively mean scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test outcome encompass four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial step of cataloging a sample in a lab’s database. This procedure confirms that the sample has been properly sealed and dispatched, assigns it an arbitrary LAN (Laboratory Accessioning Number), and fulfills any supplementary data input not catered for by an electronic chain of custody system.

Screening constitutes a preliminary inspection for illicit substances. Although Screening is a cost-efficient technique for excluding drug consumption in the majority of samples, confirmation is required for a positive result to be legally defensible. Samples that show a presumptive positive in Screening necessitate further confirmation.

Upon a presumptive positive in the Screening phase, more hair is taken from the original specimen and readied for Extraction. Within this phase, drug residues are derived from hair at a much diminished concentration relative to other methods (e.g., urine or oral fluid), hence hair drug testing is recognized as particularly challenging.

Any positive screening result is verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positive undergo washing before confirmation if necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug screenings can trace drug use up to 90 days, contrary to urine screenings that have a shorter detection span.
• Difficulty in manipulation: Cheating a hair drug screening is extremely difficult, enhancing result accuracy.
• Offers historical data: It can unveil a pattern of drug usage over time, beyond recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs become noticeable in hair only after about 5-7 days.
• Cost implications: Hair drug screenings tend to be pricier compared to alternative drug testing techniques.
• Result variations: Elements like hair color and personalized differences in hair growth can influence drug metabolite concentrations within the hair.

Note: Although often termed "hair follicle tests", the assessment targets 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.
