The Absolute Neutrophil Count (ANC) Calculator determines the number of neutrophils in your blood, which is crucial for assessing infection risk and immune system function.
Definition
Absolute Neutrophil Count (ANC) measures the total number of neutrophils (a type of white blood cell) in your blood, expressed as cells per microliter (µL).
Purpose
- Assesses infection risk (especially for chemotherapy patients)
- Monitors bone marrow function
- Evaluates immune system status in autoimmune diseases
Formula
ANC (cells/µL) = WBC ×
(Neutrophils% + Bands%)
100
How to Use the ANC Calculator
- Enter your total WBC count (from CBC)
- Input the % Neutrophils (Segs)
- Input the % Bands (if available)
- Click Calculate to get your ANC
Example Calculation
- WBC = 5,000 cells/µL
- Neutrophils = 60%
- Bands = 5%
ANC= 5000 ×
(60 + 5)
100
= 3250 (cells/µL)

Normal ANC Values
| ANC Level | Interpretation |
|---|---|
| >1,500 cells/µL | Normal |
| 1,000-1,500 cells/µL | Mild neutropenia |
| 500-1,000 cells/µL | Moderate neutropenia |
| <500 cells/µL | Severe neutropenia (high infection risk) |
Clinical Significance
- Low ANC: Increased infection risk (chemotherapy, aplastic anemia)
- High ANC: Infection, inflammation, stress response
- Critical for chemotherapy dose adjustments
Limitations
- Does not assess neutrophil function
- Must be interpreted with clinical context
- Some labs report combined “Neutrophils+Bands”
Monitor your ANC regularly during immunosuppressive treatments!
