Fibrinogen
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Fibrinogen is a soluble plasma glycoprotein (Factor I) that is converted to fibrin by thrombin during the clotting process. In a COVID Panel Hematology, it serves as an acute-phase reactant. High levels are a hallmark of the hyperinflammatory state and hypercoagulability associated with severe COVID-19, contributing to the risk of thrombosis. Conversely, a sudden drop can signal the onset of Disseminated Intravascular Coagulation (DIC) or consumption coagulopathy.

Why Context Matters
Levels can be elevated by pregnancy, oral contraceptive use, and general inflammation (e.g., rheumatoid arthritis), which might be misinterpreted as COVID-specific severity. Very high fibrinogen can also interfere with some erythrocyte sedimentation rate (ESR) tests.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
