Acute hepatitis aminotransferases are elevated to more than double their normal values. Aminotransferase levels are extremely sensitive to the loss of liver cells, and are more than doubled if acute hepatitis causes one percent liver cell damage. There are many types of aminotransferases, the most important of which are glutamine and glutamine, with glutamine being most active in the heart and glutamine being most active in the liver. In acute hepatitis, liver cells are damaged and glutamine aminotransferase is released into the bloodstream, so blood levels of aminotransferase are significantly elevated in acute hepatitis. In addition to elevated aminotransferase, acute hepatitis may also cause abnormalities in laboratory parameters such as increased bilirubin levels and decreased serum albumin levels. Elevated aminotransferase levels do not necessarily confirm the diagnosis of acute hepatitis, as hepatocellular damage can be caused by the use of liver-damaging drugs, pregnancy, and other conditions that can lead to elevated aminotransferase levels. The diagnosis of acute hepatitis is based on a combination of antibody tests and clinical symptoms. Most of the transaminase levels in patients with acute hepatitis will be significantly higher than normal, but due to the different physical condition of individuals, the level of elevation is not absolute, so it can only be used as a reference indicator. If transaminases are found to be elevated, one should consult a doctor promptly, and if necessary, undergo other relevant liver tests, and at the same time pay attention to strengthening liver protection therapy.
