Neutrophil-to-Lymphocyte Ratio
Full Form of NLR
What is NLR?
The Neutrophil-to-Lymphocyte Ratio (NLR) is a simple, cost-effective biomarker derived from a complete blood count (CBC) test. It is calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. In the Indian healthcare system, NLR is widely used in both public and private hospitals as an indicator of systemic inflammation, infection, and stress response. Its popularity stems from its availability in routine blood work without additional cost, making it particularly valuable in resource-limited settings. Doctors in India rely on NLR to assess the severity of conditions such as sepsis, COVID-19, tuberculosis, and various cancers, and to monitor treatment response. It is commonly discussed in medical wards, ICUs, and outpatient clinics across the country. For students preparing for NEET PG, AIIMS, or other medical entrance exams, NLR is a frequently tested concept, often appearing in questions about inflammatory markers or prognostic scores. Understanding NLR helps clinicians quickly gauge a patient's immune status and risk of adverse outcomes. Its simplicity and clinical utility have made it a staple in Indian medical practice, from small clinics to large tertiary care centres.
