Fibrosis-4 Score (FIB-4)
Liver blood
What It Is
FIB-4 is a calculated score using age, AST, ALT, and platelet count to estimate liver fibrosis.
Why It Matters
FIB-4 helps screen for liver fibrosis non-invasively, particularly useful for those at risk of fatty liver disease.
If Levels Are High
A high FIB-4 score suggests possible liver fibrosis and warrants further investigation.
If Levels Are Low
A low score makes significant fibrosis unlikely.
Preparation
No special preparation beyond standard blood tests.
How Often to Test
As part of liver health screening, typically annually if at risk.
