Table 1 Calculation of the Neutrophil Lymphocyte Ratio (NLR)
From: Prognostic factors in patients admitted to an urban teaching hospital with COVID-19 infection
Neutrophil Lymphocyte Ratio (NLR): | Ratio | SIRS severity |
|---|---|---|
Neutrophil count: lymphocyte count |  < 3 | Mild |
Neutrophil count: lymphocyte count | 3–5 | Moderate |
Neutrophil count: lymphocyte count |  > 5 | Severe |
