Fibrinogen, also known as factor I, is a plasma protein that can be transformed by thrombin into a fibrin gel "the clot". Fibrinogen is synthesized in the liver and circulates in the plasma as a disulfide-bonded dimer of 3 subunit chains. Fibrinogen function abnormalities, dysfibrinogenemias, may be inherited (congenital) or acquired. Patients with dysfibrinogenemia are generally asymptomatic. However, the congenital dysfibrinogenemias are more likely than the acquired to be associated with bleeding or thrombotic disorders.
No special preparation is needed for Fibrinogen. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Fibrinogen. Your doctor depending on your condition will give specific instructions.
