What it means
Fibrinogen (clotting factor I) is turned into strands of fibrin that hold a clot together. A low level is seen when clotting factors are used up, as in disseminated intravascular coagulation (DIC) or massive bleeding, and in severe liver disease. The level rises with inflammation and during pregnancy.
For the nurse
Report a low level, watch for bleeding, and handle the client gently.
