  • Neutrophil Count (10^9/L)
  • Monocyte Count (10^9/L)
  • Lymphocyte Count (10^9/L)
  • Systemic Inflammation Response Index (SIRI): Explanation and Clinical Context
    SIRI is a novel biomarker that quantifies systemic inflammation by integrating neutrophil, monocyte, and lymphocyte counts. It is calculated as (Neutrophil count × Monocyte count) / Lymphocyte count.
    This index has been studied for prognostic value in cardiovascular diseases, oncology, and sepsis. A higher SIRI reflects a greater inflammatory state, which is associated with worse clinical outcomes.
    SIRI is particularly useful for risk stratification, guiding treatment intensity, and monitoring response to anti-inflammatory therapies.
