Primary fibrinolysis is a normal body process, while secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other cause. [2] In fibrinolysis, a fibrin clot, the product of coagulation, is broken down. [3] Its main enzyme plasmin cuts the fibrin mesh at various places, leading to the production of ...
Thrombolysis, also called fibrinolytic therapy, is the breakdown (lysis) of blood clots formed in blood vessels, using medication. It is used in ST elevation myocardial infarction, stroke, and in cases of severe venous thromboembolism (massive pulmonary embolism or extensive deep vein thrombosis). [citation needed] The main complication is ...
Hyperfibrinolysis describes a situation with markedly enhanced fibrinolytic activity, resulting in increased, sometimes catastrophic bleeding. Hyperfibrinolysis can be caused by acquired or congenital reasons. Among the congenital conditions for hyperfibrinolysis, deficiency of alpha-2-antiplasmin [1] (alpha-2-plasmin inhibitor) or plasminogen ...
Fibrinolysis (simplified). Blue arrows denote stimulation, and red arrows inhibition. Plasmin is a serine protease that acts to dissolve fibrin blood clots. Apart from fibrinolysis, plasmin proteolyses proteins in various other systems: It activates collagenases, some mediators of the complement system, and weakens the wall of the Graafian follicle, leading to ovulation.
Fibrinolysis syndrome. Fibrinolysis syndrome. Other names. Defibrinating syndrome. Fibrinolysis syndrome is characterized by an acute hemorrhagic state brought about by inability of the blood to clot, with massive hemorrhages into the skin producing blackish, purplish swellings and sloughing.

Blood coagulation pathways in vivo showing the central role played by thrombin. Health. Beneficial. Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
The thrombin time (TT), also known as the thrombin clotting time (TCT), is a blood test that measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. [1]
Euglobulin lysis time. Test of. Overall fibrinolysis. The euglobulin lysis time (ELT) is a test that measures overall fibrinolysis. The test is performed by mixing citrated platelet-poor plasma with acid in a glass test tube. This acidification causes the precipitation of certain clotting factors in a complex called the euglobulin fraction.
