The eight liver function tests can find out the basic condition of liver function. It mainly includes cholinesterase, albumin, total protein, globulin, total bilirubin, direct bilirubin, glutamic oxaloacetic transaminase, glutamic alanine aminotransaminase and other indicators. Liver function eight can reflect the basic condition of liver function. The increase of cholinesterase is seen in bronchial asthma and renal insufficiency. Decrease in cholinesterase is seen in cirrhosis and malnutrition. Decreased albumin is seen in liver disease, a few malnutrition, etc. Elevated albumin is seen in patients with dehydration and hemoconcentration. Decrease in total protein is commonly seen in diarrhea, chronic liver disease, malnutrition etc. Increases are seen in hypertonic water loss, multiple myeloma. Globulins represent disturbances in immune function. Total bilirubin and direct bilirubin are indicators of abnormal bile secretion and excretion. The indicators such as glutamic oxaloacetic transaminase and alanine transaminase can reflect inflammatory damage to hepatocytes. Different indicators have different clinical significance, and the cause of liver disease should be further identified under the guidance of a doctor in order to make effective treatment.
