FIBRINOGEN, CLOTTING ACTIVITY

The fibrinogen blood test is used to assess how well the protein called fibrinogen— also called coagulation factor I — performs in the blood and to measure its levels in your blood. The test is also called the factor I (fibrinogen), serum fibrinogen, and functional fibrinogen test.

Fibrinogen is produced by the liver and is important for blood clotting. It is a protein that helps stop bleeding and support wound healing by forming clots at the site of bleeding wherever it is on your body.
