Systemic Inflammation Response Index (SIRI)

Systemic inflammation response index: ANC × AMC / ALC (Qi 2016); higher values reflect a more pro-inflammatory state.

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
