Fibrinogen Unit Converter

Fibrinogen is a protein made by the liver that plays a central role in blood clotting. When you have an injury or bleeding, fibrinogen is converted into fibrin by the enzyme thrombin, forming a mesh-like structure that helps stop bleeding and supports wound healing.

Fibrinogen is also known as coagulation factor I and is one of the most abundant clotting proteins in the blood. Normal levels typically range from 200 to 400 mg/dL.

Beyond its role in clotting, fibrinogen is an acute phase reactant. This means levels rise during inflammation, infection, or tissue injury as part of the body's immune response.

Fibrinogen is synthesized exclusively by hepatocytes in the liver. It circulates in the bloodstream with a half-life of 3-4 days, and production increases during inflammation or tissue injury.
