When fibrin polymers are cleaved by plasmin, fibrin degradation products are released. Tissue plasminogen activator initially activates plasminogen to form plasmin. Plasmin is the primary enzyme responsible of fibrinolysis. In addition to fibrin, plasmin also degrades fibrinogen, and other coagulation factors. Its action on fibrin polymers liberates dimerized D-domains of fibrin into the circulation. The crosslinking of D-dimers is the result of Factor XIII activity during the process of fibrin clot formation. As a result, an increase in circulating D-dimers suggests fibrinolysis of an intravascular clot.
