Hair Follicle Drug Testing - Pauma Valley, CA

What it is, How it works

Hair testing is now regarded as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering an extensive historical record of alcohol and drug intake. Sampling hair near the scalp can reflect a detection timeframe of up to three months for drugs and alcohol. The process of collecting hair is straightforward, not easily tampered with, and convenient for shipping.

A 1.5-inch segment containing roughly 200 hairs (approximately the thickness of a #2 pencil) closest to the scalp provides around 100mg, deemed the optimal quantity for assessment and validation. For tests including EtG, add-ons, or exceeding 10 panels, a specimen weighing 150mg is advised. It is suggested to weigh the sample using a precision scale. In the absence of scalp hair, a corresponding amount of body hair can be utilized. The term head hair specifically pertains to scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory protocol for acquiring a drug test outcome comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the lab’s database, ensuring it was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry not included in an electronic chain of custody system.

Screening acts as a preliminary assessment for drugs of abuse. While it’s a cost-efficient approach to exclude drug presence in most samples, a confirmed screen is required for legal admissibility. Samples with indicative positives in Screening necessitate verification.

If Screening suggests a positive result, further hair is extracted from the original sample and prepared for Extraction. This stage involves retrieving drugs from hair at markedly lower concentrations than other methods (e.g., urine or oral fluids), making hair drug analysis the most intricate to execute.

Confirmation of a positive screening result utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleaned before confirmation. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can disclose drug consumption over 90 days, surpassing urine tests’ shorter timeframe.
• Hard to evade: The difficulty in falsifying hair drug tests results in more precise outcomes.
• Historical usage data: It reveals drug usage patterns over extended durations rather than just recent use.

Limitations:

• Inability to trace recent usage: Detection in hair takes roughly 5-7 days post-consumption.
• Expense: Hair drug evaluations usually incur higher costs compared to alternative testing methods.
• Result variances: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the evaluation actually focuses on the hair strand, not the subcutaneous hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Pauma Valley, CA, hair follicle testing is favored over traditional urine tests due to its superior detection accuracy and reliability.

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.
