Reference Ranges Used

ANC (Absolute Neutrophil Count) - Adult 1.5–7 ×10³/µL

Formula & Clinical Notes

Formula

ANC = WBC × (Segmented neutrophils + Bands) / 100

Clinical Notes

An ANC below 1.5 × 10^9/L indicates neutropenia, and below 0.5 × 10^9/L (severe neutropenia) the infection risk is substantially increased. ANC is used to stratify febrile neutropenia risk during chemotherapy.
