Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Fibrinogen
Fibrinogen serves as both a clotting factor and cardiovascular risk marker. For older adults, monitoring fibrinogen supports comprehensive cardiovascular and coagulation assessment.
What It 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.
Why It Matters
Low fibrinogen can cause bleeding problems, while elevated fibrinogen is associated with increased cardiovascular risk and may reflect chronic inflammation.
When to Test
Testing could be indicated for unexplained bleeding, suspected DIC, liver disease assessment, cardiovascular risk evaluation, or as part of a coagulation panel.
Symptoms
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.
Lifestyle Tips
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.
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.
