Early-stage liver cirrhosis can be detected through abdominal ultrasound examinations or blood tests, such as liver function tests, liver fibrosis quartet tests, or transient elastography of the liver. Once early-stage liver cirrhosis is diagnosed, further diagnostic tests are necessary to promptly determine the underlying causes of liver cirrhosis, allowing for causal and symptomatic treatment to begin as soon as possible. After the onset of liver cirrhosis, it is crucial to regularly complete abdominal ultrasound examinations and gastroscopy to check for the presence of complications such as ascites or bleeding from esophagogastric varices, among others.
