Fibrinogen is a protein produced by the liver that plays a crucial role in blood clotting. When you get a cut or injury, fibrinogen is converted into fibrin, which forms a mesh-like structure that helps stop bleeding by trapping platelets and other cells at the injury site. In addition to its role in clotting, fibrinogen is also involved in inflammation and wound healing. High levels of fibrinogen in the blood can indicate inflammation or other health issues, making it an important marker for doctors to monitor during medical evaluations.
