The data of liver function examination is mainly to judge the liver function according to the specific test values and the normal range of reference. There are many indicators to detect liver function, mainly including transaminase, bilirubin, etc. The liver function test sheet is usually marked with the specific value of each test index and the normal reference range. For example, the normal range of transaminase is 0~40U/L. If the value of transaminase is higher than this range, it means there is liver injury. The higher the value, the more serious the liver injury. In addition, the normal reference range of total bilirubin is usually 0~17UMOL/L. If the test result is greater than this range, it means that the liver damage is serious and there may be jaundice symptoms.
