Liver Function Tests: Purpose & Normal Ranges Explained by Hepatologist

PACE Hospitals

Liver function tests (LFTs) are a group of blood tests that assess the health of the liver by measuring various enzymes, proteins, and substances produced by the liver. These tests help evaluate the liver's ability to perform essential functions, such as detoxification, protein synthesis, and enzyme production. Key parameters measured in LFTs include alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, and albumin. LFTs are commonly performed to diagnose liver diseases, monitor the progression of liver conditions, and evaluate the effectiveness of treatments. By understanding liver function, healthcare experts can make informed decisions regarding patient care and management.
