Diagnosis of patients with suspected chronic hepatitis C infection

Area of Science:

• Hepatology
• Virology
• Infectious Diseases

Background:

• Hepatitis C virus (HCV) infection is primarily detected through risk-based screening.
• Transmission routes include blood transfusions, unsafe injections, and intravenous drug use.
• Current diagnostic strategies focus on identifying at-risk populations for targeted testing.

Purpose of the Study:

• To outline the optimal approach for detecting hepatitis C virus (HCV) infection.
• To detail the available virological markers for clinical management.
• To clarify the limitations of current diagnostic and monitoring tools.

Main Methods:

• Review of current screening protocols for HCV infection.
• Analysis of serologic assays (ELISA, immunoblot) for anti-HCV antibodies.
• Evaluation of virological assays for serum HCV RNA detection (qualitative and quantitative).

Main Results:

• Optimal HCV detection relies on screening individuals with identified risk factors.
• Serologic and virologic assays are effective for diagnosis and treatment monitoring.
• These tests do not provide information on disease severity or patient prognosis.

Conclusions:

• Risk-factor-based screening remains the primary strategy for HCV detection.
• Existing assays are crucial for diagnosis and monitoring but limited in prognostic assessment.
• Patient education on preventing disease spread is essential post-diagnosis.
