Update on hepatitis B and C virus diagnosis

Area of Science:

• Hepatology
• Virology
• Clinical Diagnostics

Background:

• Hepatitis B virus (HBV) and hepatitis C virus (HCV) cause significant global chronic liver disease.
• Transmission occurs via parenteral, sexual, and vertical routes.
• Effective diagnosis is key to reducing disease burden and monitoring treatment.

Purpose of the Study:

• To review current serological and molecular diagnostic methods for HBV and HCV.
• To highlight the importance of sensitive, rapid, inexpensive, and robust analytical techniques.
• To provide an overview for effective diagnosis and antiviral treatment monitoring.

Main Methods:

• Review of established serological tests for antigen and antibody detection.
• Examination of qualitative and quantitative molecular tests for confirmation and viral load.
• Analysis of methods for genotype and resistance mutant determination.

Main Results:

• Serological tests are primary tools for initial HBV and HCV diagnosis.
• Molecular tests are essential for confirming diagnosis, quantifying viral load, and guiding treatment.
• A combination of methods ensures comprehensive diagnostic and monitoring capabilities.

Conclusions:

• Accurate and timely diagnosis of HBV and HCV is vital for patient outcomes.
• Both serological and molecular methods play critical roles in the diagnostic pathway.
• Selection of appropriate analytical methods impacts treatment efficacy and disease management.
