Absolute Neutrophil Count Calculator

The absolute neutrophil count is the white blood cell count multiplied by the share of neutrophils in the differential, and this page does that multiplication. You enter the WBC figure with its unit, the segmented neutrophil percentage and the bands percentage if the report carries one, and it returns the count in cells per microlitre and in 10^9/L. A second mode converts a neutrophil count that is already absolute between those two units. It is arithmetic on numbers copied from a laboratory report and nothing more, so it does not grade, band or interpret the answer. Reference intervals differ by laboratory and the counts that matter during treatment are set by the protocol you are on, so what a value means is a question for the team treating you.

Calculator Type

Unit of the WBC Figure

10^9/L, also written K/uL or 10^3/uL (e.g. 4.5) cells/uL, also written /mm3 (e.g. 4500)

White Blood Cell Count *

Copy the WBC figure exactly as the report prints it, then pick its unit below.

Segmented Neutrophils (%) *

May be printed as segs, polys, PMN or simply neutrophils.

Band Neutrophils (%)

Leave at zero if the differential does not report bands.
