Judging that the blood coagulation function is not good is mainly judged by the bleeding situation, as well as laboratory tests. Mainly through two aspects, one is spontaneous bleeding, and the other is bleeding after trauma or surgery.

The coagulation function is not good, that is, there is a problem with the coagulation factor, the number is reduced or the function is abnormal, and a series of bleeding symptoms will appear. Spontaneous bleeding can occur, and purpura, ecchymosis, epistaxis, gum bleeding, hemoptysis, hematemesis, hematochezia, hematuria, etc. can be seen in the skin and mucous membranes. After trauma or surgery, the amount of bleeding will increase and the bleeding time will be prolonged.

Through the inspection of prothrombin time, partially activated prothrombin time, thrombin time, fibrinogen concentration and other items, it can be checked that the coagulation function is not good, and the specific cause must be diagnosed.
