When thromboplastin activity is high, the cause of the elevated thromboplastin activity should be clarified first, and then the treatment should be directed at the cause. Plasminogen activity is an indicator for assessing the abnormality of exogenous coagulation pathway in human body, which has the same clinical significance as prothrombin time, and its normal value ranges from 75 to 100%. Plasminogen activity is associated with liver diseases, such as viral hepatitis, hepatocellular carcinoma, cholestatic hepatitis, etc. Oral anticoagulant drug warfarin may also cause elevated plasminogen activity. When the prothrombin activity is high but the patient has no obvious bleeding bleeding manifestations, it can be left untreated for the time being; if the patient has obvious bleeding manifestations, such as active bleeding from the oral and nasal cavities, black stools, hematuria, etc., it can be given fresh frozen plasma, cold precipitate, etc. for intravenous infusion. If it is caused by oral warfarin, it can be treated with vitamin K. If it is caused by viral hepatitis, it is necessary to actively anti-viral treatment, and to protect the liver and reduce enzymes and other treatments. It is recommended that the patient consult a doctor in time, and after clarifying the cause of the disease, actively target the cause of the treatment.
