Neutrophil-to-Lymphocyte Ratio (NLR)
Formula
Neutrophils / LymphocytesWhat It Reveals
Systemic inflammation and immune stress.
Interpretation Ranges
Optimal
1.0–2.0
Low systemic inflammation
Borderline
2.0–3.0
Mild systemic inflammation
High Risk
> 3.0
Significant inflammation — investigate underlying cause
Clinical Significance
NLR is an inexpensive, widely available marker of systemic inflammation. Elevated NLR predicts worse outcomes in cardiovascular disease, cancer, and infectious disease.
What To Do
Address chronic inflammation sources: sleep, stress, diet, infections. Anti-inflammatory diet (Mediterranean). Exercise moderately.
