Liver function tests

Abstract

The liver is a complex organ that has crucial role in protein, carbonhydrate and fat metabolism. It is responsible for synthesizing and secreting bile. It also synthesizes lipoproteins and plasma proteins. By glycogenesis, glycogenolysis and gluconeogenesis it maintains normal blood glucose level. Waste products of metabolism are also detoxified by liver. Abnormal liver enzyme levels may signal liver damage. Alterations in liver enzyme levels are one of the most common problems in clinical practice. Knowledge of the pathophysiology of liver enzymes is an essential guide to understanding their alteration.
