What Is a Liver Function Panel?

Q: What Is a Liver Function Panel?

Liver function panel: ALT, AST, ALP, GGT, bilirubin, albumin, total protein — assesses liver health, bile duct function, and synthetic function.

A liver function panel (LFP) assesses liver health through multiple blood tests.

Components

ALT — liver cell damage
AST — liver/heart/muscle damage
ALP — bile ducts
GGT — alcohol/bile ducts
Total bilirubin — liver processing
Albumin — liver synthetic function
Total protein — overall protein status

Interpreting Patterns

High ALT/AST = liver cell damage
High ALP/GGT = bile duct obstruction
Low albumin = chronic liver disease
High bilirubin = liver or bile duct problem
