The eight items of liver function are different from hospital to hospital, and they refer to bilirubin, albumin and transaminases, which should include at least these three parts. Bilirubin reflects the metabolism and excretion function of liver cells, so there are two types of bilirubin: conjugated bilirubin and unconjugated bilirubin, and the sum of conjugated bilirubin and unconjugated bilirubin is called total bilirubin.1 Conjugated bilirubin is bilirubin that has been processed by liver cells and can be excreted through the kidneys. It is the bilirubin that is not processed by the liver cells. The low concentration of indirect bilirubin is not harmful to the human body, but if the high concentration of bilirubin is high, it is harmful to the human body.3. Albumin mainly reflects the synthesis function of liver cells and is mainly produced by the human liver, while other places cannot produce albumin. If a person’s liver lesion is very serious, such as cirrhosis patients with reduced albumin production, it will cause the corresponding symptoms such as ascites.4. Globulin reflects a person’s immune function, not only the liver production, other lymph and spleen will produce globulin, so the liver function inside the bilirubin, albumin, globulin.5. There are two other enzymes are the most important indicators, such as glutathione and glutamic oxalacetic aminotransferase, which are the most sensitive indicators of reaction The most sensitive indicator of liver cell damage. After liver cell damage, the first manifestation is the elevation of glutathione and glutamic oxalacetic aminotransferase. Therefore, the following eight items, total bilirubin, conjugated bilirubin, indirect bilirubin, albumin, globulin, total protein, as well as ghrelin and glutamic oxalacetic aminotransferase. In fact, there are two other important enzymes in liver function, which may be listed in tertiary hospitals but may not be done in small hospitals, such as alkaline phosphatase ALP and glutamyl transpeptidase, which are two indicators of biliary excretion.
