Clinical Significance
Low levels of fibrinogen are associated with bleeding most commonly secondary to liver disease or Disseminated Intravascular Coagulation (DIC). Fibrinogen is an acute phase reactant and thus elevated levels may be associated with inflammation. Increased concentrations are also associated with increased risk of atherosclerosis.
