The eight liver function tests include total protein, direct bilirubin, total bilirubin, albumin, globulin, alanine aminotransferase, glutamine aminotransferase, cholinesterase, etc. These tests are auxiliary tests for determining the diseases related to liver function. Most of the total protein abnormalities are caused by chronic liver disease, cirrhosis, diarrhea or malnutrition; most of the direct bilirubin abnormalities are caused by biliary stasis and poor excretion; total bilirubin abnormalities are mostly seen in chronic active hepatitis, hemolytic anemia, neonatal jaundice and so on. Abnormalities of albumin are caused by liver failure or dehydration; abnormalities of globulin are mostly caused by hypercortisolism or long-term application of glucocorticoid hormones. Most of the abnormalities of alanine aminotransferase are caused by myocarditis, acute pancreatitis, biliary tract infection, etc.; most of the abnormalities of glutamic oxalate aminotransferase are caused by liver disease, nephritis, myocarditis, etc.; most of the abnormalities of cholinesterase are caused by diabetes mellitus, high blood pressure and other related causes. For example, if you are suffering from hepatitis, taking drugs for a long time or drinking alcohol for a long time and other high-risk factors that damage the liver function, you should review the liver function eight items regularly to determine whether the liver function is damaged, so that you can find out as early as possible, and use medication to treat as early as possible.
