Fibrinogen: what your result means.

A blood-clotting protein that also signals inflammation when elevated. Fibrinogen is measured by blood test as part of the Cardiovascular panel in the HodieLabs Health Blueprint.

Why Fibrinogen matters

Acute phase reactant, elevated in infection, inflammation, and post-surgery; interpret away from acute illness. Chronically elevated fibrinogen independently predicts cardiovascular events and stroke.

Associated risks when out of range: Thrombotic risk, Inflammation.

What the clinical evidence shows

The evidence base behind how the HodieLabs Evidence-Based Clinical Library interprets Fibrinogen, from randomised trials, prospective cohorts and genetic (Mendelian randomisation) studies. Full citations in the reference list below.

• Fibrinogen Studies Collaboration (JAMA 2005): individual data from 154,000+ participants in 31 prospective studies showed a log-linear association between fibrinogen and coronary heart disease, stroke and vascular mortality, clot-forming potential is measurable risk.

Evidence-based reference ranges

The HodieLabs Evidence-Based Clinical Library interprets Fibrinogen against published clinical authority standards, never arbitrary "optimal" ranges. Measured in g/L:

Clinical interpretation

• Acute phase reactant, elevated in infection, inflammation, and post-surgery; interpret away from acute illness.
• Chronically elevated fibrinogen independently predicts cardiovascular events and stroke.
• Exercise, omega-3 supplementation, and smoking cessation can modestly reduce levels.

What improves it: the evidence-based levers

• Weight reduction
• Exercise
• Stop smoking
• Address inflammation drivers

Recommended testing frequency: Annual, as part of a comprehensive panel. Single markers are always interpreted in context.

How Fibrinogen testing works at HodieLabs

Fibrinogen is measured in every Health Blueprint at our Melbourne Preventative Health & Longevity Clinic, interpreted by a doctor against the guideline-cited ranges above and tracked over time through your HodieLabs membership.
