Fibrinogen (Serum or Plasma Concentration)

Why Is This Test Done?

Your doctor may order this test to check for bleeding disorders, clotting problems, or liver disease. It can also help monitor conditions like disseminated intravascular coagulation (DIC) or certain types of anemia. Sometimes, it’s used to evaluate responses to treatments for bleeding disorders.

What Does a Low or High Level Mean?

Low fibrinogen levels may suggest bleeding disorders, liver disease, or conditions that cause excessive clotting breakdown. High levels could indicate inflammation, infections, or certain blood disorders. Your doctor will interpret results in the context of your overall health and symptoms.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is collected in a tube that separates serum or plasma from cells. This sample is then sent to a lab for analysis. You may be asked to fast for a few hours before the test, but this depends on your doctor’s instructions.

Common Conditions Monitored

Fibrinogen levels are often checked in people with suspected bleeding disorders (like hemophilia), liver disease, or those undergoing treatments that affect clotting. It may also be monitored in patients with inflammatory conditions or those who have recently had surgery.
