What is meant by fibrinogen? or Define fibrinogen.


1 Answer


Fibrinogen is a plasma protein which helps in clotting of blood by forming insoluble fibrin. 

Fibrinogen (factor I) is a glycoprotein complex, made in the liver, that circulates in the blood of all vertebrates. During tissue and vascular injury, it is converted enzymatically by thrombin to fibrin and then to a fibrin-based blood clot. Fibrin clots function primarily to occlude blood vessels to stop bleeding.

A normal value for fibrinogen is between 200 and 400 mg/dL. A fibrinogen value of less than 50 mg/dL may mean you're in danger of bleeding after surgery. A fibrinogen value of more than 700 mg/dL may mean you're in danger of forming clots that could harm your heart or brain.Fibrinogen, or factor I, is a blood plasma protein that's made in the liver. Fibrinogen is one of 13 coagulation factors responsible for normal blood clotting. When you start to bleed, your body initiates a process called the coagulation cascade, or clotting cascade.
