# FIB-4

> The FIB-4 index uses your age and standard blood test results to estimate the amount of scarring, or fibrosis, in your liver. This calculation helps doctors assess liver health in people with conditions like Hepatitis C or fatty liver disease to see if significant damage is present. It is often used to determine if advanced scarring is unlikely, which can help you avoid invasive procedures like a liver biopsy. However, this test is an estimation tool and cannot diagnose the specific cause of liver disease or confirm the exact stage of scarring on its own.
