Active hepatitis often indicates that the disease is progressing and that factors causing liver damage persist, and it is best to first identify which type of hepatitis it is. If left untreated, it can become prolonged. The diagnostic indicator most indicative of active hepatitis is liver function. The degree of abnormality in liver function varies with the progression of the disease, with elevated serum transaminases, transpeptidases, alkaline phosphatase, total bilirubin, decreased albumin, elevated globulin, and an imbalance in the white-to-ball ratio during the active phase. Also coagulation is abnormal, often suggesting prolonged prothrombin time, and blood tests suggesting leukocytosis and thrombocytopenia. In case of active hepatitis caused by acute pathogenic bacterial infection, there may also be increased immunoglobulins, especially IgG and complement are often decreased, and rheumatoid factor may be positive in active patients, all of the above indicators have a certain diagnostic value for active hepatitis.
