Test Details


  • ActiTest
  • FibroSure®
  • FibroTest


Assessment of liver status following a diagnosis of HCV. Baseline determination of liver status before initiating HCV therapy. Posttreatment assessment of liver status six months after completion of therapy. Noninvasive assessment of liver status in patients who are at increased risk of complications from a liver biopsy.


This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA). The FDA has determined that such clearance or approval is not necessary.

Reference Interval
