1, Blood routine:Reduced hemoglobin, platelets, and leukocytes.
2, Liver function tests:Mild abnormalities in the compensatory stage, decreased serum protein, increased globulin, and A/G inversion. Prothrombin time prolongation, decreased prothrombin activity. Elevated transaminases and bilirubin. Total cholesterol and cholesterol esters decrease, blood ammonia may increase. Disordered amino acid metabolism, imbalance in branched/essential amino acid ratio. Increased blood urea nitrogen and creatinine. Electrolyte disturbance: low sodium, low potassium.
3, Pathogenic examination:HBV-M or HCV-M or HDV-M negative.
4, Fibrosis examination:PⅢP levels rise, prolyl hydroxylase (PHO) rises, monoamine oxidase (MAO) rises, and serum laminin (LM) rises.
5, Ascites examination:Patients with newly onset ascites or those with rapid increase of pre-existing ascites of unknown cause should undergo abdominal puncture, and abdominal fluid should be drawn for routine examination, adenosine deaminase (ADA) measurement, bacterial culture, and cytological examination. To improve the positive rate of culture, abdominal fluid culture should be performed at the bedside using blood culture bottles, and separate aerobic and anaerobic bacterial cultures should be performed.
