Fibronectin is generally one of the four liver fibrosis tests, and its value generally represents the possibility of liver fibrosis, but simply an elevated fibronectin is not an absolute diagnosis of cirrhosis and liver fibrosis. At this time, the patient also needs to further check the ultrasound of the upper abdomen, and if necessary, to do the liver hardness test. The liver hardness test can reveal whether the patient has the possibility of liver fibrosis. The degree of liver fibrosis can also be determined by this test. Patients also need to take blood to check liver function, and if they have chronic viral hepatitis B, they also need to take blood to check hepatitis B DNA; if it suggests that there is viral replication, combined with liver function damage, then we should actively consider taking antiviral drugs or injecting interferon to carry out antiviral treatment. If the patient’s liver fibrosis is indicated by the four liver fibers, and the patient’s liver hardness test also suggests that there is liver fibrosis, it should be noted that on the basis of antiviral treatment, usually pay attention to rest, absolutely avoid alcohol, and moderately take anti-fibrotic medicines such as turtle turtle turtle soft liver tablets to carry on the treatment.
