October 13, 2024 is World Thrombosis Day. Thrombotic diseases can be divided into arterial thrombosis and venous thrombosis. Bed rest and prolonged immobility are important risk factors for the occurrence of venous thrombosis.

Norman's Fibrinogen Degradation Products (FDP) and D-Dimer, can assist in diagnosis of thrombotic diseases. FDP can reflect the function of the fibrinolytic system and determine intravascular coagulation, thrombosis, etc. D-Dimer is an important molecular marker that reflects the hypercoagulable state of plasma and the activation of the fibrinolytic system in the body. These two parameters are sensitive indicators that reflect the formation and dissolution of thrombus in the body.
