The aminotransferase ratio is usually defined as the ratio of alachlor aminotransferase to alanine aminotransferase, and the normal range of values is usually between 0.8 and 1.5. Glutaminase is distributed mainly in the hepatocyte plasma and mitochondria, whereas AST is mainly distributed in the hepatocyte plasma. When the value of AST is higher than that of AST, it reflects different diseases. If the patient is acute hepatitis or chronic hepatitis light, although the patient has hepatocyte damage, but generally the liver cell mitochondria are mostly in the intact state, the release into the blood is mainly in the hepatocyte plasma glutamine transaminase, when the glutamine transaminase is elevated, caused by the patient’s glutamic acid to glutamic acid aminotransferase ratio is generally slightly greater than the normal value. When the patient has severe hepatitis and chronic hepatitis of medium and severe, the mitochondria of the liver will also be destroyed, and in this case the ghrelin to ghrelin ratio is usually greater than normal. In patients with cirrhosis or hepatocellular carcinoma, when liver cell destruction occurs, the mitochondria are also destroyed, and the ghrelin-to-albumin transaminase ratio may be significantly greater than normal, and may remain elevated. It is recommended to seek early medical attention and take appropriate measures under the guidance of a doctor if the AST ratio is abnormal.
