Summary
A new automated diagnostic system offers rapid and accurate Hepatitis C virus (HCV) detection at the point-of-care. This cost-effective molecular test uses a microfluidic chip for efficient screening, aiding global HCV elimination efforts.
Area of Science:
- Virology
- Molecular Diagnostics
- Biotechnology
Background:
- Hepatitis C virus (HCV) affects approximately 3% of the global population, necessitating enhanced screening for the World Health Organization's (WHO) 2030 elimination goal.
- Current standard HCV testing methods are often time-consuming, costly, and difficult to implement in remote or underserved regions.
- There is a critical need for a cost-effective, rapid, and accurate point-of-care (POC) diagnostic test to manage HCV and reduce its public health and economic impact.
Purpose of the Study:
- To develop and present a fully automated reverse-transcription loop-mediated isothermal amplification (RT-LAMP)-based molecular diagnostic system for rapid Hepatitis C virus (HCV) detection.
- To create a cost-effective, sensitive, and specific diagnostic solution suitable for point-of-care applications, particularly in resource-limited settings.
Main Methods:
- A novel automated diagnostic setup was designed, integrating a disposable microfluidic chip, a compact surface heater, and a reusable magnetic actuation platform.
- The microfluidic chip automates plasma sample processing and utilizes SYBR green dye for naked-eye detection of amplified Hepatitis C virus (HCV) genetic material.
- The system's performance was evaluated using human plasma samples spiked with known concentrations of HCV virions.
Main Results:
- The automated RT-LAMP system achieved a limit of detection as low as 500 virions/mL for Hepatitis C virus (HCV).
- The entire viral detection process, from sample to result, was completed within 45 minutes.
- The microfluidic chip demonstrated high sensitivity and specificity in detecting Hepatitis C virus (HCV) in human plasma samples.
Conclusions:
- The developed automated microfluidic chip-based RT-LAMP assay provides a rapid, sensitive, and specific method for Hepatitis C virus (HCV) detection.
- This inexpensive, disposable, and self-driven diagnostic system represents a significant advancement for point-of-care (POC) Hepatitis C virus (HCV) screening.
- The system has the potential to facilitate widespread HCV testing and contribute to the global goal of HCV elimination by 2030.
