- Diagnostic evaluation (mild, moderate, severe).
- Monitor disease progression.
- Distinguish among different types of liver disorder.
How are LFTs classified under synthetic function?
- Serum proteins:
- Albumin: marker of chronicity, low serum half-life.
- Immunoglobulins: compensatory production.

What are the serum enzymes involved in LFTs?
- ALT, AST: indicating hepatocellular damage.
- ALP, GGT: indicating obstruction.
