Lymphocyte-to-Monocyte Ratio (LMR)
Lymphocyte-to-monocyte ratio: absolute lymphocyte count / absolute monocyte count; a prognostic inflammation marker where a lower value is less favorable.

Example
- Absolute lymphocyte count
- 2.0 ×10³/µL
- Absolute monocyte count
- 0.5 ×10³/µL
Result: Lymphocyte-to-monocyte ratio 4 — interpretation is context-dependent (a lower value is less favorable).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- value
- LMR = ALC / AMC. A prognostic inflammation marker; a lower value is less favorable. No universal cutoff — context-dependent.
What you enter
- Absolute lymphocyte count
- Absolute monocyte count
