Fibrinogen is a protein that is a blood coagulation factor (Factor 1). It’s involved in blood clotting. This test evaluates the fibrinogen level in the blood to detect thrombosis or blood clotting disorder.

Why Fibrinogen Test?


Fibrinogen is also called coagulation factor-1. Fibrinogen is one of 13 coagulation factors responsible for normal blood clotting. Fibrinogen is a protein formed by the liver that is released into the bloodstream. Fibrinogen has a key role in coagulation and thrombosis. Moreover, fibrinogen being an acute-phase protein is found to increase inflammations as an inflammatory response. Thrombin is an enzyme that converts the fibrinogen protein to fibrin that binds to platelets and other serum proteins to form a hemostatic plugin in the process of blood clotting. During an injury when the tissues or blood vessels are injured, the coagulation cascade is initiated by the platelets and clotting factors are triggered which activates a series of cascades to form a clot. Fibrinogen test is also called factor-1 test, serum fibrinogen test, functional fibrinogen test etc. Fibrinogen test is a helpful tool hence performed to check for bleeding or clotting factor disorders. There are two types of fibrinogen blood tests, they are the fibrinogen antigen test –which measures the amount of fibrinogen in the blood, and the fibrinogen activity test – it checks how well fibrinogen functions to form a clot. When the fibrinogen levels are deficient or if the fibrinogen has a functional defect it will result in excessive bleeding. This test is also performed along with prothrombin time (PT), partial thromboplastin time (PTT) or thrombin clotting time (TCT) etc, which suggests clotting problems, in pathologies like DIC, screening for liver disease, medications to prevent blood clots, family history of bleeding or clotting disorders etc. This test is also ordered as a screening test to find the cause of abnormal bleeding such as clinical manifestations of excessive bruising, excessive bleeding from gums, frequent nose bleeding, GIT bleeding, blood in urine, bloody stools etc. High fibrinogen is associated with infection, inflammation, cancer, RA, Nephrotic syndrome, heart attacks, stroke, pregnancy, recent surgery, diabetes, obesity, age over 60 years, sitting in one position for long periods like on a plane etc. Low fibrinogen levels are associated with liver disease, DIC, cancer, malnutrition, inherited or congenital blood clotting disorders, frequent blood transfusion etc. Some of the factors that may influence this test are OCPs, vigorous exercise, medications like spreptokinase, valproic acid, phenobarbital, anabolic steroids etc.
