NLR is a simple hematologic index derived from complete blood count differentials. It is used as a general inflammation and stress marker in many clinical settings, though interpretation is context-dependent.
Formula: NLR = Absolute Neutrophil Count / Absolute Lymphocyte Count.
Higher NLR values often suggest increased inflammatory or physiologic stress, while lower values are generally less inflammatory in pattern.
Use NLR as an adjunct marker when CBC differential data are available and inflammatory burden or risk trends are being assessed.
NLR is non-specific and affected by infection, steroids, stress response, malignancy, and chronic inflammatory disease. It should not be used as a standalone diagnostic decision tool.
For related assessments, see 4T Score (HIT), DIC Score and SOFA Score.

Calculate the 4T score for heparin-induced thrombocytopenia (HIT) pretest probability. Score ≤3: >99% NPV for HIT. Intermediate/High (≥4): stop heparin, start alternative anticoagulation.
HematologyEstimate overt disseminated intravascular coagulation probability using the ISTH scoring framework.
EmergencyCalculate the SOFA score to assess organ dysfunction severity in critically ill patients. Scores range from 0 to 24 across six organ systems.
EmergencyCalculate qSOFA bedside sepsis risk score. A score of 2 or more (altered mentation, RR ≥22, SBP ≤100) flags high-risk infection requiring urgent evaluation.
