Clinical Significance
Elevated concentrations of fibrinogen in the plasma are to be expected in inflammatory processes, after major trauma surgery (acute-phase protein), in metastasizing tumors, and after serious operations. Diminished levels of fibrinogen can occur in consumption coagulopathies, (e.g., DIC or disseminated intravascular coagulation), primary hyperfibrinolysis, liver damage, and genetic deficiency (i.e., hypo- or dysfibrinogenemia).
