What is a Liver Function Test (LFT), and why is it important?

A Liver Function Test (LFT) is a blood test that evaluates the health of your liver by measuring levels of enzymes, proteins, and bilirubin in your blood. It helps diagnose and monitor liver diseases such as hepatitis, fatty liver, or cirrhosis. LFTs also assess liver damage caused by medications, alcohol, or infections. Regular testing is essential for those at risk of liver conditions, including people with a history of heavy alcohol use, hepatitis, or obesity. Early detection through LFT can prevent complications and guide timely treatment.
