Fibrinogen
Why the test is performed:
This test may be performed when abnormal blood clotting is present, particularly if there is excessive bleeding. Text Continues Below
Fibrinogen is a protein produced by the liver. Fibrinogen helps stop bleeding by helping blood clots to form. During normal blood clotting: - Fibrinogen is broken down by an enzyme called thrombin into short fragments of fibrin. Thrombin also activates a substance called Factor XIII.
- Factor XIII helps weave the fibrin fragments into a complex lattice, closing off injured blood-vessel walls.
- Blood platelets attach to the fibrin fragments, clumping together to form blood clots and stop bleeding.
