NLR Calculator (Neutrophil-to-Lymphocyte Ratio)

Your details

Absolute mode uses cells/µL directly from your CBC. Percentage mode converts differential percentages with the total WBC.
Absolute neutrophil count from your CBC report, in cells per microlitre.

NLR is 2.25 - Normal.

  • An NLR between 1 and 3 is considered normal for a healthy non-elderly adult. No further action is indicated on this marker alone.
  • Your ANC (4,500 cells/µL) and ALC (2,000 cells/µL) produced this ratio. Both values should also be assessed against their own reference ranges.
  • NLR is a screening marker, not a diagnosis. It should always be interpreted in the full clinical context of the patient.

Next stepTrending NLR over serial CBCs has been shown to be more useful prognostically than a single reading. Discuss your result with a healthcare provider for clinical interpretation.
