Perform HCV Viral Load Testing with Greater Efficiency

HCV infection is one of the main causes of chronic liver disease worldwide.1 Fortunately, with detection and appropriate therapy, the majority of HCV-infected individuals can be cured. The European Association for the Study of the Liver (EASL) recommends response-guided therapy for HCV, which includes the monitoring of treatment efficacy using a real-time PCR-based assay, with a lower limit of detection of 10-20 IU/mL.2 The VERSANT® HCV RNA 1.0 Assay (kPCR)*, which has a limit of detection of 15 IU/mL, provides excellent precision across the dynamic range and 100 percent specificity. Additionally, the assay features technology that is compatible with all HCV genotypes, providing clinicians the information that they need to manage patient therapy.
