The liver function tests mainly include glutamic and glutamic oxalacetic transaminases, as well as total bilirubin, direct bilirubin, indirect bilirubin, total protein, albumin, globulin, and alkaline phosphatase, GGT, and some patients will check bile acids and other related tests. Generally, the examination of the above indicators can mostly reflect the general status of liver function and whether it is in a healthy state. If there is an elevation of glutathione and glutamic oxalacetic transaminase, the patient should be considered to have liver function damage, and the cause of liver function damage should be further investigated. If the patient has elevated total bilirubin, the possibility of jaundice is considered, especially if the total bilirubin is above 34.2 μmol/L. The possibility of jaundice is considered. In this case, the cause of the elevated bilirubin should be determined based on whether the elevated direct bilirubin or the elevated indirect bilirubin is the main cause. If total bilirubin and direct bilirubin are mainly elevated, combined with elevated alkaline phosphatase and GGT, the patient is considered to have obstructive factors, that is, obstructive factors in the bile ducts. If indirect bilirubin and total bilirubin are predominantly elevated, jaundice is most likely to be caused by necrosis of liver cells. In addition, if albumin decreases, the patient will show generalized swelling and fluid accumulation in the peritoneal and pleural cavities. In this case, the patient needs to actively treat the pleural fluid and ascites, and intravenous infusion of plasma and albumin for supportive treatment.
