It contains cross-linked regions introduced during clot stabilization. D-dimer is produced naturally as part of the wound healing process. The formation of blood clots and their subsequent lysis is part of the normal healthy functions of the body, these events occur naturally every time a skin cut or graze is effected. Hemostasis occurs in both health and in certain disease states or vascular injury, the latter culminating in extensive fibrin clot formation forming an insoluble barrier at the injury site. This is called Coagulation, or Fibrin formation.
Tissue healing occurs with gradual clot digestion or Fibrinolysis.
Fibrinolysis completes the haemostatic process.
