Hepatology 5 is a test for the metabolism of the human liver, mainly including total bilirubin, direct bilirubin, alanine aminotransferase, glutamic oxalamine aminotransferase and albumin, and the specific items may not be exactly the same in different hospitals. 1. Total bilirubin: the total amount of bilirubin in the blood, including direct bilirubin and indirect bilirubin. Elevated bilirubin may indicate liver damage, biliary obstruction or hemolytic disease. 2. Direct bilirubin: protein-bound bilirubin in the blood. Elevated direct bilirubin may indicate intrahepatic cholestasis or biliary obstruction. 3. alanine aminotransferase: an enzyme found in liver cells. Elevation is usually indicative of liver damage, such as hepatitis, cirrhosis, and fatty liver. 4. Glutamine aminotransferase: an enzyme found in the liver, heart muscle, muscle and other tissues. Elevation may indicate liver damage, but its specificity is low. 5. Albumin: a major plasma protein synthesized by the liver. Decreased albumin may indicate hepatic hyposynthesis, malnutrition, or kidney disease. No alcohol should be consumed and fasting for 8-10 hours before the Liver Panel test; people who need to do the Liver Panel test are recommended to do it under the guidance of a doctor.
