Fibrinogen is the final coagulation protein in the clotting cascade.The conversion of fibrinogen to fibrin by thrombin eventually forms the cross linked gel to physically block the damaged blood vessel. A routine coagulation screen includes a derived (calculated) fibrinogen level. This is based on the turbidity of the blood clot obtained when a prothrombin time is performed.
