Fibrinogen is also called serum fibrinogen, plasma fibrinogen and factor I is a soluble plasma glycoprotein that is synthesised by the liver.

Fibrinogen is converted into fibrin - a protein involved in the clotting of blood (forms a clot over a wound site).

Fibrinogen levels are very important indicator for your body’s overall health condition. That is why fibrinogen blood tests are used. They are to evaluate your body’s ability to form and break down blood clots.

Fibrinogen Blood levels between 150-300 mg/dL are considered normal, and higher than 460 mg/dL means you are at risk.

Lowered fibrinogen concentration in your blood may lower your body’s ability to form stable blood clot. It may be due to afibrinogenemia (no production of fibrin) or to liver disease or malnutrition (which leads to hypofibrinogenemia).

Some types of cancer may cause consumption of fibrinogen, which leads first to bad clot formation excessive bleeding.

High fibrinogen levels may increase the risk of developing a blood clot, which in turn may cause cardiovascular disease over time.
