A liver function test is a set of blood tests that assess the health and functionality of the liver. It includes measurements of various enzymes, proteins, and substances in the blood, such as ALT, AST, alkaline phosphatase, bilirubin, and albumin. These tests help diagnose and monitor liver conditions, such as hepatitis, cirrhosis, or fatty liver disease. Liver function tests provide valuable information about the liver’s ability to process and filter substances, aiding in the early detection and management of liver disorders. Professional interpretation of the results is crucial for accurate assessment and informed medical decisions.
