Liver hardness kPa is the unit of liver hardness, and the specific measurement is the result obtained by measuring the transient under ultrasound, which reflects the degree of liver fibrosis and cirrhosis, and can indirectly determine whether the patient has liver fibrosis or cirrhosis. Since ultrasound measurement is generally non-invasive, accurate and timely, the results can be obtained within a short period of time, and the normal value is generally about 2.4-7.8 kPa. However, since the measurement has errors, whether the patient has liver fibrosis and cirrhosis needs to be judged comprehensively, and the degree of cirrhosis of the patient will be considered after combining the patient’s ultrasound as well as gastroscopy, blood routine, liver function, coagulation function and other comprehensive examinations and whether there is cirrhosis or not. If the patient’s liver hardness test indicates cirrhosis, further blood tests are needed to see whether the virus has replicated and whether the results of the liver fibrillation test support the conditions of liver fibrosis and cirrhosis.
