Liver function I and Liver function II are mainly referred to by patients as different items of liver function tests, and patients are generally checked for liver function as liver function V, liver function VIII, and liver function complete set, as a way of checking. Liver function five generally includes glutamic oxal transaminase, as well as the patient’s total bilirubin, direct bilirubin, indirect bilirubin. For the hepatic panel of eight, it is possible to add further correlations such as total protein, albumin, and globulin to the patient’s total protein, albumin, and globulin. The complete set of liver function also includes the patient’s alkaline phosphatase, GGT, as well as cholinesterase, bile acids and other correlation tests, which can generally reflect the functional status of the liver through liver function tests. In addition, it can see whether the patient’s liver function reserve is sufficient. If the patient has the elevation of glutamic oxal transaminase, it mostly indicates that the patient has liver function damage and liver insufficiency, at this time, the patient should further improve the examination to see the cause of liver insufficiency, whether it is due to the necrosis of hepatocytes or due to the correlation symptoms caused by the patient after having viral hepatitis. In addition, if necessary, it is also necessary to draw blood to check the correlation of autoimmune hepatitis to see whether there is the possibility of autoimmune hepatitis.
