The specific items of liver function tests are not exactly the same in different hospitals. Generally speaking, the 12 liver function tests mainly include total bilirubin, direct bilirubin, indirect bilirubin, alanine aminotransferase, glutamic oxaloacetic aminotransferase, glutamyltransferase, alkaline phosphatase, total protein, globulin, albumin, cholesterol, cholinesterase, and so on, which reflect the basic functional status of the liver.
The 12 items of liver function are used to check the liver function and understand the specific situation of liver function. For example, total bilirubin reflects the degree of jaundice, and is mainly used to diagnose occult jaundice. Direct bilirubin is used to identify the type of jaundice. Indirect bilirubin is clinically used to diagnose liver diseases, hepatocellular jaundice, hemolytic diseases, and so on.
Fasting is required before the liver function test, and the diet should be light for a few days before the test, regular rest, avoid strenuous exercise, and do not take a shower for 24 hours after the test.
