📊 Monocyte-to-Lymphocyte Ratio (MLR)
UseWhen to use: protocols reporting MLR/LMR from CBC differentials.
StrataCutoffs are disease-specific; LMR is the reciprocal.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Input mode | Absolute counts (×10⁹/L) |
|---|---|
| Monocytes (absolute) | 0.6 ×10⁹/L |
| Lymphocytes (absolute) | 2.0 ×10⁹/L |
| WBC (if % mode) | 8.0 ×10⁹/L |
| Monocytes % (if % mode) | 8 % |
| Lymphocytes % (if % mode) | 25 % |

FAQ
Frequently asked questions
- Does Monocyte-to-Lymphocyte Ratio (MLR) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Monocyte-to-Lymphocyte Ratio (MLR) calculated in practice? Can you show a worked example?
- Inputs: Input mode Absolute counts (×10⁹/L), Monocytes (absolute) 0.6 ×10⁹/L, Lymphocytes (absolute) 2.0 ×10⁹/L, WBC (if % mode) 8.0 ×10⁹/L, Monocytes % (if % mode) 8 %, Lymphocytes % (if % mode) 25 % → Result: MLR 0.30（Mono abs: 0.60, Lymph abs: 2.00, LMR (inverse): 3.33） Inputs: Input mode WBC + monocyte% + lymphocyte%, Monocytes (absolute) 0.6 ×10⁹/L, Lymphocytes (absolute) 2.0 ×10⁹/L, WBC (if % mode) 8.0 ×10⁹/L, Monocytes % (if % mode) 8 %, Lymphocytes % (if % mode) 25 % → Result: MLR 0.32（Mono abs: 0.64, Lymph abs: 2.00, LMR (inverse): 3.13）
