Interpretation of HCV Test Results
These results confirm active chronic hepatitis C virus infection with high viral load requiring treatment evaluation. 1
What These Results Mean
Your test results indicate the following:
- Reactive HCV antibody: You have antibodies to hepatitis C virus, indicating exposure to HCV at some point 1
- Detectable HCV RNA at 4,110,000 IU/mL (log10 6.614): This confirms active, ongoing viral replication and current HCV infection 1
- High viral load: Your viral load of 4.1 million IU/mL represents a high baseline viral burden 2
Clinical Significance
You have chronic hepatitis C infection that requires medical management. 1 The combination of positive antibody with detectable HCV RNA at this level definitively establishes active infection rather than past cleared infection or false-positive antibody result. 3, 4
Understanding the Viral Load
- Modern quantitative HCV RNA assays using real-time PCR have a detection limit of 12-15 IU/mL and can measure up to 7-8 log IU/mL with 98-99% diagnostic specificity 1
- Your log10 value of 6.614 (equivalent to 4,110,000 IU/mL) indicates substantial viral replication 1
- Important caveat: HCV RNA levels do not correlate with severity of liver inflammation or fibrosis, so this high number does not necessarily mean more advanced liver disease 1
Next Steps Required
Immediate Actions
- HCV genotype testing must be performed before treatment to determine optimal therapeutic regimen 1
- Liver function assessment including ALT, AST, and assessment of fibrosis stage (via elastography or biopsy) 1
- Baseline laboratory evaluation for treatment planning 1
Treatment Considerations
- You are a candidate for direct-acting antiviral therapy regardless of viral load 1
- The same laboratory should be used for all monitoring during and after treatment, as different laboratories can vary in viral quantification results 1
- Treatment response will be monitored using the same quantitative HCV RNA assay 1
Common Pitfalls to Avoid
- Do not assume high viral load means worse prognosis: Viral load does not predict disease severity or treatment response in the direct-acting antiviral era 1
- Do not delay genotyping: This is essential for treatment selection and cannot be skipped 1
- You are infectious: Standard precautions apply, and you should not donate blood, organs, or tissue 3
- Antibodies persist indefinitely: Even after successful treatment, your HCV antibody will remain positive, so HCV RNA testing will be needed to confirm cure 1
Reinfection Risk
Anti-HCV antibodies are not neutralizing antibodies and do not provide protective immunity—you can be reinfected if exposed again after successful treatment 1, 3
