Indirectly high bilirubin and normal alanine aminotransferase may be exacerbation of hepatitis, cholestasis and hemolytic disease. 1. Exacerbation of hepatitis: hepatitis patients usually have different degrees of aminotransferase elevation in the early stage of the disease, with the development of the disease, bilirubin will gradually appear to be elevated, when the disease is more serious, there may be a decrease in aminotransferase, which is clinically known as bilirubin, when the disease is in a more serious stage. 2. Cholestasis: when the patient has intrahepatic bile duct injury, it will affect the secretion of bile, so that the bile in the liver siltation, resulting in increased bilirubin levels, the initial aminotransferase may not have obvious changes, then the patient may also appear indirect bilirubin high glutamic alanine aminotransferase is normal. 3. Hemolytic diseases: such as hemolytic anemia, will cause the destruction of red blood cells increased, resulting in increased production of indirect bilirubin, then there is no obvious change in liver function, aminotransferase levels are not affected, the patient shows high indirect bilirubin glutamic transaminase normal. If the patient has long-term indirect bilirubin high glutamine aminotransferase normal situation, it is recommended to consult a doctor in time to find out the cause of the disease, to carry out targeted treatment, so as not to delay the condition.
