A liver stiffness of 9.0 indicates the presence of moderate fibrosis in the liver, which is generally more severe and should be treated promptly. The normal value of liver stiffness determined by the liver elastometry technique, which is a non-invasive test for liver tissue stiffness, is generally (5.5±1.6) kPa, which is independent of age, but is slightly higher in men than in women (5.8±1.5 vs. 5.2±1.6 kPa). According to the limit of liver fibrosis according to the elasticity value, generally ≤7.0kPa for F0 ~ F1 stage (no liver fibrosis or mild fibrosis); 7.0kPa ~ 9.5kPa for F2 stage (moderate liver fibrosis), 9.5 ~ 12.5kPa for F3 stage (severe liver fibrosis), ≥12.5kPa for F4 stage (cirrhosis). Normal liver function and virus negative means that the liver function is not damaged and there is no virus infection, liver hardness of 9.0 means that the liver is in moderate liver fibrosis, which is more serious because liver fibrosis can lead to cirrhosis when it reaches a certain degree, and it should be actively consulted for medical treatment to slow down the development of the disease.
