Online Absolute Neutrophil Count (ANC) Calculator: The Absolute Neutrophil Count (ANC) is frequently used to assess risk of opportunistic infection.An ANC less than 1500 cells/µL is defined as neutropenia.
The ANC is not measured directly. It is derived by multiplying the WBC count times the percent of neutrophils in the differential WBC count. The percent of neutrophils consists of the segmented (fully mature) neutrophils) + the bands (almost mature neutrophils). The normal range for the ANC = 1.5 to 8.0 (1,500 to 8,000/mm3).
What causes high neutrophil levels?
Neutrophilia can point to a number of factors:
