Point-of-Care Testing for Hepatitis Viruses: A Growing Need

Area of Science:

• Virology
• Public Health
• Diagnostic Technology

Background:

• Viral hepatitis remains a significant global health issue, causing millions of infections annually.
• Chronic infections with HBV, HCV, and HDV lead to severe liver complications and are often underdiagnosed.
• The World Health Organization aims to eliminate viral hepatitis by 2030, a goal hindered by current diagnostic limitations.

Purpose of the Study:

• To explore the potential of point-of-care (POC) testing for viral hepatitis diagnosis, monitoring, and surveillance.
• To highlight the need for simpler, faster, and less expensive diagnostic methods to meet elimination targets.
• To identify unmet needs and research gaps in POC viral hepatitis diagnostics.

Main Methods:

• Discussion of potential methods for POC testing of viral hepatitis markers (antibodies, antigens, nucleic acids).
• Review of existing POC formats and identification of areas requiring further development and validation.
• Exploration of applications for POC testing in clinical settings outside traditional laboratories.

Main Results:

• Existing POC tests for viral hepatitis markers are limited, necessitating further innovation.
• Novel technologies and additional markers are required for comprehensive POC viral hepatitis diagnostics.
• POC testing offers a promising avenue to improve diagnosis rates and facilitate hepatitis elimination efforts.

Conclusions:

• Point-of-care testing is a critical strategy to accelerate the achievement of global viral hepatitis elimination goals.
• Further development and validation of POC diagnostic tools are essential for widespread clinical adoption.
• Addressing unmet needs in POC technology will improve the diagnosis, monitoring, and surveillance of viral hepatitis infections.
