Normal aminotransferases and high bilirubin are not necessarily abnormal liver function, but may also be abnormal bile function, hemolysis, or physiologically elevated bilirubin. Bilirubin is divided into direct bilirubin and indirect bilirubin, and total bilirubin is the sum of direct bilirubin and indirect bilirubin. Bilirubin is an important indicator of liver function, and jaundice occurs when bilirubin is elevated. The normal value of direct bilirubin is 0-6.8 μmol/L, and the normal value of indirect bilirubin is 1.7-10.2 μmol/L. When indirect bilirubin is elevated, it may be caused by hemolysis, hepatitis, hepatocellular carcinoma and other diseases. When direct bilirubin is elevated, it may be caused by diseases such as gallstones, cholangitis, and pancreatitis. Elevated bilirubin may also be physiologic, and this condition may subside on its own. When the aminotransferase is normal and bilirubin is high, you should go to the hospital in time to clarify the cause of the disease, so as not to delay the condition.
