Educational information only. At Precursor, blood testing is requested and reviewed by a clinician and considered alongside your history and other markers, not as a stand-alone diagnosis. Testing is performed in NATA-accredited laboratories to ISO 15189 standards.

What is fibrinogen?

Fibrinogen is a protein made by the liver that is essential for blood clotting, forming the mesh that holds a clot together. It is also an acute-phase protein, meaning it rises during inflammation, so it sits at the intersection of clotting and inflammatory health.

Why it matters

Fibrinogen offers a dual insight. As a clotting factor it reflects your blood's tendency to form clots, and as an inflammatory marker it can contribute to the picture of cardiovascular risk. This makes it a useful, if less commonly discussed, addition to an inflammation panel.

What your results can mean

Higher than optimal

A raised fibrinogen can reflect inflammation and is associated with a greater tendency to clot, which is relevant to cardiovascular risk. It is interpreted alongside your other markers.

Within the healthy range

A fibrinogen in range suggests a normal balance in this part of the clotting and inflammatory system.

Reference ranges in Australia

Fibrinogen is reported in grams per litre (g/L), with laboratory-specific reference ranges, and can rise temporarily with infection, injury or pregnancy. Read your result against your own report and with a clinician.

Understanding your inflammation with Precursor

Fibrinogen is best read alongside your other inflammatory and heart markers. At Precursor, this testing is requested and reviewed by a clinician, so your result is read in context. If this is something you would like to understand, you can speak with Precursor's clinical team about whether testing is right for you.
