From the Guidelines
Yes, this patient requires treatment for Hepatitis C due to the presence of active infection as indicated by a high HCV RNA level of 1310 IU/mL (log10 of 3.117) and a positive HCV antibody test with a signal-to-cutoff ratio >11.0. The laboratory results confirm chronic HCV infection, which necessitates antiviral therapy unless there are contraindications such as a short life expectancy that cannot be improved with treatment 1.
Key Considerations for Treatment
- The current standard of care for chronic HCV infection involves direct-acting antiviral (DAA) regimens, which are typically administered for 8-12 weeks depending on the specific genotype, presence of cirrhosis, and treatment history.
- Common first-line regimens include glecaprevir/pibrentasvir (G/P) for 8 weeks or sofosbuvir/velpatasvir (SOF/VEL) for 12 weeks in most patients without cirrhosis, as outlined in the 2017 AASLD/IDSA guidelines 1.
- Before initiating treatment, additional testing should be performed, including:
- HCV genotyping to determine the most appropriate treatment regimen.
- Assessment for liver fibrosis/cirrhosis to evaluate the extent of liver damage.
- Hepatitis B status to rule out co-infection.
- Baseline laboratory tests to monitor for potential side effects and treatment response.
Expected Outcomes of Treatment
- Treatment of HCV is highly effective, with cure rates exceeding 95% using modern DAA regimens 1.
- Successful treatment prevents progression to cirrhosis, liver cancer, and liver failure, significantly improving morbidity, mortality, and quality of life for patients with chronic HCV infection.
- The choice of treatment regimen should be individualized based on patient-specific factors, including HCV genotype, presence of cirrhosis, and prior treatment experience, to maximize the likelihood of achieving a sustained virologic response (SVR) 1.

The FDA drug label does not answer the question.
From the Research
Hepatitis C Treatment
The provided test results indicate a Hepatitis C virus (HCV) infection with the following details:
- HCV Ab: >11.0
- HCV Quantitation: 1310 IU/mL
- HCV log10: 3.117 log10 IU/mL
Treatment Requirements
Based on the studies, treatment of HCV infection is recommended to reduce all-cause mortality and liver-associated complications 2. The goal of therapy is to achieve sustained virological response (SVR), which is defined as undetectable plasma HCV RNA 12 or 24 weeks after therapy completion 3.
Treatment Options
The treatment options for HCV infection depend on various factors, including genotype, extent of fibrosis or cirrhosis, prior treatment, comorbidities, and potential adverse effects 2. For patients with HCV genotype 1, treatment with sofosbuvir + pegylated interferon + ribavirin is recommended 3. For patients with HCV genotypes 2 and 3, treatment with sofosbuvir + ribavirin alone is recommended 3.
Difficult-to-Treat Patients
Some patients may be considered difficult-to-treat due to unreached sustained virological response, potential drug side effects or interactions, or co-morbidities 4. In such cases, salvage regimens such as the combination of sofosbuvir, glecaprevir/pibrentasvir, and ribavirin may be considered 5, 6.
