People often have their liver function checked during health checkups and disease tests. What are the indicators of liver function? How to understand the abnormal liver function indicators? Usually, the indicators of liver function are: total bilirubin, direct bilirubin, albumin, globulin, glutamic oxaloacetic transaminase, glutamic alanine transaminase, and in special cases, alkaline phosphatase, G-glutamyl transpeptidase, cholinesterase, prothrombin time, etc. The above-mentioned liver function indicators can reflect the damage of liver cells, the reserve function of liver, and the secretion function of liver cells, and all these abnormalities of liver can be diagnosed by liver function indicators. In general, elevated total bilirubin, direct bilirubin, globulin, glutamic oxaloacetic transaminase and glutamic alanine transaminase reflect acute liver injury, such as acute hepatitis, chronic hepatitis activity, decompensated cirrhosis or advanced liver cancer; decreased serum albumin, cholinesterase and prolonged prothrombin time reflect poor liver reserve function, such as decompensated cirrhosis; elevated alkaline phosphatase and G-glutamyl transpeptidase Elevated alkaline phosphatase and G-glutamyl transpeptidase can reflect both chronic damage of liver function and biliary obstruction, such as cirrhosis, obstructive jaundice, etc.
