The CAP value refers to the value of liver stiffness measured by the patient’s liver stiffness test. The normal value is usually between 2-7 KPA, and a patient’s liver stiffness is considered normal in this range. If the patient’s liver stiffness test result is between 7-9 KPA, the patient may have mild liver fibrosis. If between 9-12.5 KPA, the patient may have liver fibrosis. If the liver hardness test result suggests greater than 12.5 KPA or more, the patient is more likely to be considered to have cirrhosis. For the above results, patients also need to take blood for liver fibrillation quadruple test, with the results of liver fibrillation quadruple test to consider the possibility of liver fibrosis and cirrhosis, if there is the possibility of liver cirrhosis and liver fibrosis, we should actively look for the cause of liver fibrosis or cirrhosis, the most common cause is viral hepatitis. The most common cause of viral hepatitis is viral hepatitis. The most fundamental treatment for viral hepatitis is to control the patient’s viral replication, while giving appropriate liver-protective treatment and anti-fibrotic treatment.
