The AEC Calculator helps you determine the Absolute Eosinophil Count (AEC) in your blood. AEC is an important value used by doctors to assess allergies, asthma, parasitic infections, and other medical conditions involving eosinophils.

What is Absolute Eosinophil Count (AEC)?

Absolute Eosinophil Count is the total number of eosinophils in your blood per microliter (µL). Eosinophils are a type of white blood cell that plays a role in your immune system, especially in allergic reactions and fighting off parasites.

Formula to Calculate AEC

AEC = (Total WBC Count × % Eosinophils) ÷ 100

Example:
WBC Count = 8000 cells/µL
Eosinophils = 6%
AEC = (8000 × 6) ÷ 100 = 480 cells/µL

Normal AEC Range

  • Normal: 30 to 350 cells/µL
  • Mild elevation: 350–1500 cells/µL
  • Moderate: 1500–5000 cells/µL
  • Severe: Above 5000 cells/µL

When Should You Use the AEC Calculator?

  • If you have symptoms of allergies or asthma
  • If your doctor suspects a parasitic infection
  • To monitor chronic eosinophilic conditions
  • During regular blood test evaluations

Why is AEC Important?

High or low AEC levels can give clues about the immune system’s activity. Elevated AEC may indicate allergies, skin diseases, autoimmune conditions, or infections. Knowing your AEC helps doctors diagnose and monitor these issues effectively.

Conclusion

The AEC Calculator is a fast and useful tool to estimate your Absolute Eosinophil Count. It gives better insights into your immune health and helps support accurate diagnosis and treatment planning. Always discuss your results with a healthcare provider for proper understanding and advice.
