Absolute Neutrophil Count (ANC) Calculator

Calculate your infection risk level from complete blood count (CBC) results in seconds. Essential for chemotherapy patients and those with immune concerns.

WBC Count (×10³/µL)

Normal range: 4.5-11.0 ×10³/µL

Neutrophils (%)

Typical range: 40-60%

Bands (%) (optional)

Immature neutrophils (usually 3-5%)

Understanding Absolute Neutrophil Count (ANC)

ANC measures your body's ability to fight infections by calculating the number of neutrophil granulocytes (a type of white blood cell) in your bloodstream. This critical value is especially important for:

Cancer patients undergoing chemotherapy
Individuals with bone marrow disorders
Patients recovering from severe infections
Those with autoimmune conditions affecting blood cells

ANC Interpretation Guidelines:

ANC Range (cells/µL)	Risk Level	Clinical Significance	Recommended Actions
> 1,500	Normal	Normal infection resistance	Routine monitoring
1,000-1,500	Mild Neutropenia	Minimal increased risk	Monitor for changes
500-999	Moderate Neutropenia	Increased infection risk	Take precautions, consult doctor
< 500	Severe Neutropenia	High risk of serious infection	Immediate medical attention

ANC Calculation Formula:

ANC = WBC (×10³/µL) × (Neutrophils% + Bands%) × 10

Example: For WBC 5.0 ×10³/µL, Neutrophils 50%, Bands 5% → ANC = 5.0 × (50 + 5) × 10 = 2,750 cells/µL

When ANC Matters Most:

During chemotherapy treatment cycles
When experiencing unexplained fevers
Prior to dental procedures for at-risk patients
When signs of infection appear (fever, chills)

Neutropenia Precautions:

Practice meticulous hand hygiene
Avoid crowds and sick contacts
Cook foods thoroughly
Monitor for fever (≥100.4°F/38°C)
