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.

What does a high absolute neutrophil count mean?

Having a high percentage of neutrophils in your blood is called neutrophilia. This is a sign that your body has an infection. Neutrophilia can point to a number of underlying conditions and factors, including: infection, most likely bacterial. noninfectious inflammation.

What does a low absolute neutrophil count mean?

If the neutrophil count is very low, fewer than 500 neutrophils in a microliter of blood, it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.

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:

  • surgery
  • smoking
  • heart attacks
  • stress
  • infection
  • noninfectious inflammation
