Suspicion of cirrhosis usually requires laboratory tests such as routine blood and urine tests, liver function tests, hepatitis B two halves, imaging tests such as ultrasound and CT, and some special tests such as liver puncture, among which liver puncture is the most accurate. 1. Laboratory tests: including routine blood test, urine test, routine stool test, hepatitis B two-half pairs, liver function test, alpha-fetoprotein, etc., which can clarify whether there are elevated white blood cells, urinary proteins, gastrointestinal bleeding and abnormalities in liver function. 2. Imaging examination: including ultrasonography, CT examination, magnetic resonance imaging and other examinations, which can check the condition of the liver and understand the severity of cirrhosis. 3. Some special tests: including liver puncture, laparoscopy, ascites, portal vein manometry and other tests, which are important for early diagnosis of cirrhosis and diagnosis of the cause of ascites. If you suspect liver cirrhosis, you need to go to the hospital in time, cooperate with the doctor to carry out the relevant examinations, and get early treatment after diagnosis.
