Liver function test items

In modern urban life, people have more and more social gatherings at the drinking table and are becoming more and more tired in life. As a result, the burden on the liver is gradually increasing, and the incidence of liver disease is also rising. Then liver examination has become a physical examination that people pay attention to. Here let us learn about liver function tests.

The liver function test is to detect various metabolic indicators of the liver through biochemical tests to display some basic conditions of liver function. There are many liver function tests, but not all of them need to be done for one patient. The doctor needs to choose the specific test based on the patient's medical history and symptoms.

Liver function tests usually include: alanine aminotransferase, aspartate aminotransferase, total protein, albumin, globulin, albumin/globulin and total bilirubin. The examination of these items can reflect the indicators of liver parenchymal damage, the indicators reflecting bilirubin metabolism and cholestasis, the indicators reflecting the liver's synthetic function, the indicators reflecting liver fibrosis, and the detection indicators reflecting the liver's coagulation function.

Recently, the relevant departments have added five new inspection items: bile acid (CG), ferritin (SF), prealbumin (PA), transferrin (TF), and bile acid (TBA).

The eight liver function tests include: 1. Normal total protein (TP): 60-80g/L; 2. Normal globulin (G): 20-29g/L; 3. Normal albumin (Alb): 40-55g/L; 4. Normal aspartate aminotransferase (AST): 0-50μmol/L; 5. Normal alanine aminotransferase (ALT): 0-40μmol/L; 6. Normal total bilirubin (STB): 1.7-17.1μmol/L for adults; 7. Normal direct bilirubin (DBIL): 0-3.4μmol/L; 8. Normal cholinesterase (CHE): colorimetric method: 130-310U/L.

Liver function tests can help people understand whether there are any problems with their livers, and can help prevent and treat various liver and gallbladder diseases such as acute and chronic hepatitis, alcoholic liver disease, and cirrhosis in advance. During the examination, it is important to note that you should be on an empty stomach before the examination, preferably for 8-12 hours; avoid spicy and greasy food the night before the examination, and remember not to drink alcohol; do not stay up late before the examination, otherwise it will increase the transaminase level and cause abnormal examination results.
