What you need: absolute neutrophil and lymphocyte counts from a standard CBC with differential.
NLR Inflammation Marker
How to use this calculator
Enter the absolute neutrophil and lymphocyte counts from a standard complete blood count (CBC) with differential β both in the same units (e.g. 10^3/Β΅L), as reported on your lab result.
What your result means
NLR (Neutrophil-to-Lymphocyte Ratio) is a simple, widely-used marker of systemic low-grade inflammation ("inflammaging"), calculable from a routine, inexpensive CBC with no specialized inflammatory markers needed. A ratio between 1.0-2.0 is commonly considered favorable; higher values are associated in research with more systemic inflammation and higher all-cause mortality risk.
"Had these numbers sitting unused on an old lab report β nice to finally know what they meant."

"No extra bloodwork needed since it is just standard CBC numbers β that is what sold me on trying it."

Questions and answers
What is NLR?
The neutrophil-to-lymphocyte ratio (NLR) comes from a routine blood count. Researchers study it as a general marker of inflammation.
What is a normal NLR?
Values of roughly 1 to 3 are often cited for healthy adults, but ranges differ by lab and population. Interpret your result with a clinician.
