Albuminum aminotransferase is a sensitive indicator of the degree of liver damage. The normal test range is 0-40iu/mL.The higher the alanine aminotransferase, the more severe the damage to the liver cells, mainly inflammation and necrosis of liver cells. Clinically, it can be categorized as mild, moderate, or severe elevation. An aminotransferase of 300iu/mL suggests moderate elevation, but the condition is not severe. There are many reasons for the elevation of alanine aminotransferase, commonly including acute and chronic viral hepatitis, drug hepatitis, toxic hepatitis, alcoholic fatty liver, non-alcoholic fatty liver, hepatitis cirrhosis, primary biliary cholangitis, primary sclerosing cholangitis, and so on; it can also be seen in staying up late at night, resting poorly, and strenuous exercise, and so on. Elevated alanine aminotransferase in the treatment of the main cause of treatment and symptomatic treatment, if viral hepatitis caused by the need for antiviral therapy, hepatoprotective and enzyme-lowering drugs, oral commonly used Baisenuo, six flavors of the Wuling tablets, compound glycyrrhizic acid diamine enteric capsule, ShuiLinJia and so on; intravenous drip drug magnesium isoglycyrrhizinate, compound glycyrrhizic acid glycoside, and so on.
