Fibrinogen is an important protein produced in the liver. It plays a key role in the formation of blood clots, helping to stop bleeding. When an injury occurs in the body, fibrinogen is converted into another protein called fibrin during the blood clotting process. Fibrin fibers form a strong mesh that seals the wound and initiates healing. The level of fibrinogen in the blood is measured by a fibrinogen test. This test is used to evaluate bleeding disorders or clotting problems. Low or high fibrinogen levels can be an indicator of various health conditions or underlying diseases. For instance, high fibrinogen levels may indicate inflammation or a risk of thrombosis, while low levels can carry a risk of excessive bleeding. Therefore, abnormal fibrinogen levels should be carefully evaluated.
