The examination methods of hereditary cirrhosis include blood test, ultrasonography, CT examination and liver puncture. 1. Blood test: Venous blood sampling is performed after clarifying whether the patient has a history of hepatitis or alcohol consumption, etc. If the result shows that the number of white blood cells and red blood cells in the peripheral blood is lower than the normal value, it may indicate the presence of liver disease. 2. Ultrasonography: Ultrasonography can determine the hardness and morphological changes of the liver. If the patient is found to have liver surface not smooth, unbalanced proportion of liver lobes or uneven echogenicity of liver parenchyma, etc., hereditary cirrhosis may exist. 3. CT examination: if the CT examination shows irregular liver margins, atrophy of the right liver, relative enlargement of the left liver and widening of the portal vein, etc., it means that the patient may have hereditary cirrhosis. 4. Liver puncture: patients need to take liver tissue by liver puncture for biopsy to further clarify whether they have hereditary cirrhosis. It is recommended to go to regular hospitals for hereditary cirrhosis related examination and comprehensive diagnosis by professional doctors, and not to judge blindly by oneself.
