Area of Science:

  • Hepatology
  • Virology
  • Medical Diagnostics

Background:

  • Hepatitis C Virus (HCV) infects nearly 60 million globally, causing liver cirrhosis and hepatocellular carcinoma.
  • High-burden populations (IDUs, LMICs) face diagnostic barriers due to slow, costly current methods.
  • HCV lacks a vaccine, and asymptomatic infection necessitates effective screening to prevent liver damage and transmission.

Purpose of the Study:

  • To review current commercial standards and novel improvements in Hepatitis C Virus diagnostics.
  • To outline a framework for developing a one-step diagnostic test for HCV.
  • To address the unmet needs in HCV diagnosis for high-risk and underserved populations.

Main Methods:

  • Review of current commercial Hepatitis C Virus diagnostic platforms.
  • Analysis of emerging diagnostic technologies including isothermal amplification and viral protein analytes.
  • Evaluation of streamlined, self-contained testing systems for reduced complexity.

Main Results:

  • Current HCV diagnostics are often slow and expensive, hindering timely treatment.
  • Novel approaches show promise for rapid, sensitive, and accessible Hepatitis C Virus detection.
  • Improvements focus on simplified workflows and reduced need for specialized laboratory infrastructure.

Conclusions:

  • Advancements in HCV diagnostics are crucial for global health equity.
  • Integration of novel techniques can lead to a more efficient, one-step diagnostic solution.
  • Future diagnostics must prioritize accessibility and affordability for populations most affected by Hepatitis C Virus.
