Test Name Alias

Fibrinogen Blood Level | 8413

Interface Order Alias

10040

Clinical Information

Useful for the quantitative determination of fibrinogen in plasma. 

 

Depressed levels of fibrinogen may be of acquired or congenital origin.  An acquired fibrinogen deficiency may occur as result of intravascular proteolysis of fibrinogen by thrombin, snake venoms, or plasmin.  Moderate hypofibrinogenemia my occur in the case of diminished production, increased loss, or degradation of fibrinogen.  Fibrinogen is an acute phase protein and depending on the clinical state, may lead to temporary, transitory, or persistent hyperfibrinogenemia.  Levels of fibrinogen increase slightly with age.
