Fibrinogen Test
Fibrinogen is a protein produced by the liver that plays a dual role as both a clotting factor and an acute-phase reactant. It is converted to fibrin by thrombin to form blood clots, and its levels rise during inflammation, infection, and tissue damage.
Doctor's Assessment Included
Fibrinogen: what this test measures
This test measures the concentration of fibrinogen in your blood. As both a clotting protein and inflammatory marker, fibrinogen provides information about coagulation function and systemic inflammation.
Fibrinogen: why this value matters
Low fibrinogen can cause bleeding problems, while elevated fibrinogen is associated with increased cardiovascular risk and may reflect chronic inflammation.
Fibrinogen: how the blood test works
- Referral
- No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
- The draw
- A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.
- Which test
- on its own €33,-
- Where
- 650+ draw sites run by independent laboratories across the Netherlands. Draw sites
Fibrinogen: when is testing worthwhile?
Testing could be indicated for unexplained bleeding, suspected DIC, liver disease assessment, cardiovascular risk evaluation, or as part of a coagulation panel.
Fibrinogen: symptoms of a high or low value
Low Levels
Low fibrinogen may cause excessive bleeding from cuts, easy bruising, prolonged bleeding after dental work or surgery, and heavy menstrual bleeding. Very low levels may indicate DIC or severe liver disease.
High Levels
Elevated fibrinogen is an independent cardiovascular risk factor and is associated with increased risk of heart attack, stroke, and peripheral arterial disease.
Fibrinogen: lifestyle and this value
Regular exercise, a healthy weight, not smoking, and an anti-inflammatory diet can help optimise fibrinogen levels. Omega-3 fatty acids have been associated with lower fibrinogen in some studies.
Fibrinogen: frequently asked questions
Is fibrinogen a risk factor for heart disease?
Yes. Elevated fibrinogen is an independent cardiovascular risk factor. It increases blood viscosity and promotes clot formation.
Can stress affect fibrinogen?
Yes. As an acute-phase reactant, fibrinogen can rise temporarily with physical or emotional stress, infection, and inflammation.
What is DIC?
Disseminated intravascular coagulation (DIC) is a serious condition where widespread clotting depletes fibrinogen and other clotting factors.
