The normal value of the activity of thromboplastin is 75% to 100%, and the activity of thromboplastin 143 is classified as increased, and whether it is serious or not needs to be clarified as to the cause of its increase. Increased plasminogen activity is often seen in abnormal liver function diseases, such as acute hepatitis, cirrhosis, liver tumors, vitamin K deficiency and so on. It can be seen that thromboplastin activity is an important indicator reflecting the good or bad coagulation function of the liver and functional judgment, which is closely related to the degree of severity of the disease. When patients have abnormal prothrombin activity, they should follow the doctor’s instructions to find out the specific reasons, and should not judge or diagnose by themselves according to a test result, but should consult the doctor in time, who will analyze and diagnose according to the specific situation.
