🧫 ANC Calculator – Calculate Absolute Neutrophil Count Instantly
The ANC Calculator, or Absolute Neutrophil Count Calculator, is a vital medical tool used to evaluate a person’s immune system by estimating the number of neutrophils in the blood. It’s especially critical for patients undergoing chemotherapy, those with infections, or individuals with immune disorders.
At Calculators.at, our free ANC Calculator helps healthcare professionals and patients determine ANC quickly and accurately using basic blood test values.
🔍 What Is ANC?
ANC (Absolute Neutrophil Count) measures the number of neutrophils—white blood cells that help fight infections. It's calculated using values from a complete blood count (CBC) test, specifically:
- Total WBC count (white blood cell count)
- Percentage of neutrophils (includes both segmented neutrophils and bands)
🧮 ANC Formula
The formula for ANC is:
ANC = WBC × (% Neutrophils + % Bands) ÷ 100
Where:
- WBC = White blood cell count (in cells per microliter, typically ×10³/µL)
- Neutrophils + Bands = % of neutrophils (segmented) and immature forms
Example:
- WBC = 4.0 ×10³/µL
- Neutrophils = 50%
- Bands = 5%
- ANC = 4.0 × (50 + 5) ÷ 100 = 2.2 ×10³/µL
✅ Why Is ANC Important?
- 🛡️ Monitors immune function in cancer, HIV, or bone marrow diseases
- ⚠️ Identifies risk of infection (neutropenia)
- 💊 Guides treatment decisions in chemotherapy
- 📈 Tracks recovery from bone marrow suppression
- 🧪 Essential for hospital discharge and admission protocols
