Q: How the absolute neutrophil count (ANC) is calculated?
Answer: The definition of Neutropenia is an absolute neutrophil count (ANC) of less than 1500/microL.
The formula to calculate ANC is
ANC = WBC (cells/microL) x percent (PMNs + bands) ÷ 100
The objective of this question is to highlight the fact that both polymorphonuclear cells (PMNs) and band forms from the differential should be used to obtain accurate ANC.
