Fibrinogen (Serum or Plasma Mass Concentration)

What Is Fibrinogen?

Fibrinogen is a key protein in your blood that plays a vital role in forming clots. When you get a cut or injury, fibrinogen helps stop bleeding by converting into fibrin, which creates a mesh that traps blood cells to form a clot. Low levels may increase bleeding risk, while high levels could raise clot formation risks.

Why Might You Need This Test?

Doctors may order a fibrinogen test to check for bleeding disorders, clotting issues, or conditions like liver disease, where fibrinogen production might be affected. It’s also sometimes used in monitoring treatments for conditions like disseminated intravascular coagulation (DIC).

Common Reasons for Testing

Common reasons include diagnosing bleeding problems, evaluating liver function, assessing clotting disorders, or monitoring treatments for conditions that affect blood clotting.

How Is the Test Done?

A blood sample is taken from a vein, usually in your arm. The sample is sent to a lab where fibrinogen levels are measured using a specialized test that detects its concentration in your blood.
