This is a blood test to determine the amount of fibrinogen in the blood. Fibrinogen is a very important part of the blood-clotting system. It is converted to fibrin by action of thrombin during the clotting process. Low levels of fibrinogen are found in patients with liver disease, persons that have had large amounts of blood transfusions, malnourishment, and certain clotting disorders.
