Thrombelastography (TEG) is a whole blood test, which is from the beginning of blood coagulation, to the formation of blood clots and the whole process of fibrin dissolution, which is widely used in clinical practice. Compared with the traditional method of coagulation testing, TEG is more close to the physiological state, and reflect the whole picture of the coagulation of patients more authentic and accurate. This paper focuses on the principle of TEG in a comprehensive analysis of the coagulation/fibrinolysis status of patients with thrombosis and hemorrhagic diseases, its clinical significance in patients with the timing of surgery, monitoring of anticoagulation factors, bleeding reason analysis, the use of blood products. Disseminated intravascular coagulation (DIC) and venous thromboembolism risk assessment, etc. The analysis will help clinicians to access timely and effective information, and to take reasonable treatment measures for patients with thrombosis and hemorrhagic disease.
