Liver tests, also known as liver function tests or liver chemistries, are carried out to diagnose liver damage and associated diseases. The tests typically involve drawing blood samples to measure specific proteins, enzymes, and other substances produced by the liver. A single blood sample can help determine the level of the following components: Bilirubin: A waste product produced by the liver Total protein: The total amount of protein in the blood Albumin: A protein produced in the liver Globulin: Proteins made by liver ALT (alanine transaminase), ALP (alkaline phosphatase), gamma-glutamyl transferase (GGT), LDH (lactate dehydrogenase) and AST (aspartate aminotransferase): Different enzymes produced by the liver and indicates liver injuries, damage or dysfunctions Prothrombin time (PT): A protein that helps blood clotting appropriately Apart from these, tests that detect autoimmune liver disorders, fibrosis, steatosis, cirrhosis, and genetic involvement in liver diseases are also tested at Metropolis Labs.
