Fibrinogen
The Fibrinogen blood test measures the level of fibrinogen, a protein produced by the liver that plays a crucial role in blood clotting. Fibrinogen is converted into fibrin during the clotting process, helping blood clots form and stabilise to stop bleeding after injury. Because of its central role in coagulation, fibrinogen is an important marker of both clotting function and inflammation.
In addition to its role in clot formation, fibrinogen levels can rise in response to inflammation, infection, or tissue injury. Measuring fibrinogen can therefore provide useful information when assessing bleeding or clotting disorders, cardiovascular risk, or inflammatory conditions.

What is fibrinogen and why is it important?
Fibrinogen is one of several clotting factors circulating in the blood. When bleeding occurs, fibrinogen is converted into fibrin strands that form a mesh, helping to create a stable blood clot. This process is essential for preventing excessive blood loss.
Beyond clotting, fibrinogen also behaves as an acute-phase protein, meaning its levels can increase during inflammation or infection. For this reason, fibrinogen testing can reflect both clotting ability and underlying inflammatory activity.
Why might I need a fibrinogen test?
A fibrinogen test may be recommended if you have unexplained bleeding or bruising, a history of blood clots, or if you are being investigated for a clotting or bleeding disorder. It may also be requested before surgery or during the assessment of certain liver conditions.
The test is sometimes used as part of cardiovascular risk assessment, as elevated fibrinogen levels have been associated with an increased risk of heart disease and stroke. It can also help monitor inflammatory conditions or response to treatment.
What do the results mean?
Low fibrinogen levels may increase the risk of bleeding and can be seen in certain inherited or acquired clotting disorders, liver disease, or severe illness. High levels may indicate inflammation, infection, pregnancy, or an increased tendency toward clot formation.
Results are always interpreted alongside symptoms, medical history, and other clotting tests. Your healthcare professional will explain what your fibrinogen level means for you and whether further investigation is needed.
How is the test performed?
The fibrinogen test is performed using a blood sample collected during a short appointment. The procedure is routine, and our clinical team will ensure you are comfortable throughout.
Do I need to prepare?
No special preparation or fasting is required for this test unless you have been advised otherwise.
