Non-invasively aids in the detection, staging, and monitoring of the severity of liver fibrosis for hepatitis C virus (HCV) patients.


For hepatitis C (HCV) patients, we offer the PROMETHEUS FIBROSpect HCV test, which is a laboratory-developed test that aids in in the detection, staging, and monitoring of liver fibrosis. The simple blood test is noninvasive and provides a quantitative fibrosis score to help physicians risk stratify and monitor patients

  • Differentiates between F0-F1 and F2-F4 liver fibrosis9
  • Validated with samples from 348 biopsy-confirmed HCV patients9

Staging of Liver Fibrosis in HCV Patients is Critical

American Association for Study of Liver Disease (AASLD) and Infectious Disease Society of America (IDSA) 2017 guidelines highlight the benefits of initiating therapy in HCV patients with lower-stage liver fibrosis10:

  • “Initiating therapy in patients with lower-stage fibrosis augments the benefits of SVR [sustained virologic response]”
  • “Treatment delay may decrease the benefit of SVR”
