  5. Fibrinolytic Pathway Fibrinolysis is initiated when fibrin is formed and eventually dissolves the clot.

  6. Fibrinolytic Pathway PAI-1 Plasminogen Tissue Plasminogen Activator (t-PA) Urokinase (uPA) Exogenous: streptokinase Plasmin Inhibitor XL-Fibrin, fibrinogen Plasmin XL- fibrin degradation products (FDP)

  7. Fibrinogen or Fibrin Fragment X Small Peptides Fragment Y Fragment D Small Peptides Fragment E Fragment D Small Peptides Degradation of Fibrin/Fibrinogen Plasmin Plasmin Plasmin

  8. Approach to evaluate Fibrinolysis D-Dimer, a measure of fibrin degradation products, is the final product formed during the fibrinolysis process by plasmin
