What Are Liver Function Tests?
Definition and Purpose
Liver function tests are a series of blood tests designed to evaluate the overall health of the liver. They help detect liver inflammation, damage, or disease, and monitor the progression of liver conditions or the effectiveness of treatment.
Common Indicators Measured in LFTs
LFTs assess various enzymes, proteins, and substances in the blood, including:
- Alanine aminotransferase (ALT)
- Aspartate aminotransferase (AST)
- Alkaline phosphatase (ALP)
- Gamma-glutamyl transferase (GGT)
- Total bilirubin
- Direct bilirubin
- Serum albumin
- Prothrombin time (PT)
