There is no question of which is more accurate, liver fiber IV or liver elasticity test, both can be used as a diagnostic basis for chronic liver diseases and complement each other. 1. Liver Fibre IV is mainly used to determine the degree of liver fibrosis in patients, and the clinical indicators mainly include type III pre-collagen, type IV collagen layer, adhesion protein and hyaluronidase. Among them, hyaluronidase is a sensitive indicator of liver fibrosis and liver cirrhosis, and the increased level of adhesion protein indicates the possible existence of esophageal varices. 2. Liver elasticity test is mainly to determine the fat content and fibrosis degree of the liver, to determine whether there is fatty liver and to determine the severity of liver fibrosis, but the test results may be affected by excessive abdominal fat layer and abdominal distension, which may lead to errors. Clinical examination of liver fibrosis and liver hardness need to make a comprehensive judgment, and also need to be combined with the patient’s liver function, alpha-fetoprotein and other values for diagnosis, it is recommended to consult the Department of Gastroenterology in regular hospitals.
