Systemic Inflammation Response Index (SIRI)
Systemic inflammation response index: ANC × AMC / ALC (Qi 2016); higher values reflect a more pro-inflammatory state.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Absolute neutrophil count
- 4.0 ×10³/µL
- Absolute monocyte count
- 0.5 ×10³/µL
- Absolute lymphocyte count
- 2.0 ×10³/µL
Result: Systemic inflammation response index 1 — interpretation is context-dependent.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- value
- SIRI = ANC x AMC / ALC. Higher values reflect a more pro-inflammatory state. No universal cutoff — context-dependent.
What you enter
- Absolute neutrophil count
- Absolute monocyte count
- Absolute lymphocyte count
