Aug 30, 2011 · The ANC is calculated as follows: ANC = white blood cells (microlitre) x percent (polymorphonuclear cells + bands)/100. [ Absolute neutrophil count ] An ANC <1500/microlitre or <1.5 x 10⁹/L is defined as neutropenia and graded as follows: [3] As the ANC falls below 1000/microlitre or 1 x 10⁹/L, the risk of infection progressively increases.
