Noninvasive estimate of liver scarring in HCV and HBV patients, to assess need for biopsy.
When to Use
Please fill out required fields.
- Low fibrosis scores may be appropriate candidates for medical management and may not require liver biopsy if FIB-4 scores continue to stay low.
- Severe fibrosis/cirrhosis scores may need liver biopsy for confirmation of cirrhosis unless there are other clinical or imaging signs of progression to end-stage liver disease.
