Fibrinogen-to-Albumin Ratio (FAR)
Fibrinogen-to-albumin ratio: fibrinogen (mg/dL) / serum albumin (g/dL); an inflammation / prothrombotic marker where higher values are less favorable.

Example
- Fibrinogen
- 400 mg/dL
- Serum albumin
- 4.0 g/dL
Result: Fibrinogen-to-albumin ratio 100 — interpretation is context-dependent.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- value
- FAR = fibrinogen (mg/dL) / albumin (g/dL). Higher values are less favorable. Reporting conventions vary. No universal cutoff — context-dependent.
What you enter
