| | Fibrinogen test |
 | | Other conditions related to decreased fibrinogen levels are those in which fibrinogen is completely absent (congenital afibrinogenemia), conditions in which levels are low (hypofibrinogenemia), and conditions of abnormal fibrinogen (dysfibrinogenemia). | | | Fibrinogen plays two essential roles in the body: it is a protein called an acute-phase reactant that becomes elevated with tissue inflammation or tissue destruction, and it is also a vital part of the "common pathway" of the coagulation process. | | | This test is not recommended for patients with active bleeding, acute infection or illness, or in those patients who have received blood transfusions within four weeks. |

| | fibrinogen - definition of fibrinogen in Encyclopedia |
| | Fibrinogen is a 340-KD glycoprotein synthesised in the liver hepatocytes and megakaryocytes, which normally has a concentration between 1.5 - 4.0 g/L (normally measured using the Clauss method) in blood plasma. | | | Processes in the coagulation cascade activate the zymogen prothrombin to the serine protease thrombin, which is responsible for converting fibrinogen into fibrin. | | | Fibrin is then cross linked by factor XIII to form a clot. |

| | This is reported as an INR value when used for the dosing of oral anticoagulants such as warfarin. | | | If a coagulation factor is part of the contact or tissue factor pathway, a deficiency of that factor will affect only one of the tests: thus hemophilia A, a deficiency of factor VIII, which is part of the contact factor pathway, results in an abnormally prolonged aPTT test but a normal PT test. | | | Measurement of the exact amount of fibrinogen present in the blood is generally done using the Clauss method for fibrinogen testing. |

| | Additional conditions under which the test may be performed: | | | This is a test that measures the amount of fibrinogen in the blood. | | | This test may be performed when abnormal blood clotting is present, particularly if there is excessive bleeding. |
