Factor I

Fibrinogen is a glycoprotein complex, synthesized in the liver. It circulates in blood and if a vascular tissue injury happens, it is converted enzymatically to thrombin and then to a fibrin-based clot. Its primary function is to occlude blood vessels to stop bleeding.
Interpretation:If fibrinogen levels are high, the risk of blood clotting increases, which can in turn, contributes to increased heart and coronary diseases and stroke. High fibrinogen levels may be seen in inflammation, tissue damage, trauma and infection, because it is an acute phase reactant. If the levels are low, it means that the patient has the risk of bleeding after surgery.
