Absolute Eosinophil Count Formula:
| From: | To: |
Absolute Eosinophil Count (AEC) is a calculation that determines the actual number of eosinophils in the blood. It's derived from the total white blood cell count and the percentage of eosinophils, providing a more accurate assessment than the percentage alone.
The calculator uses the AEC formula:
Where:
Explanation: The formula converts the percentage of eosinophils into an absolute count by multiplying it with the total white blood cell count and dividing by 100.
Details: AEC is crucial for diagnosing and monitoring various conditions including allergic disorders, parasitic infections, autoimmune diseases, and certain types of cancers. It provides a more precise measurement than relative percentages alone.
Tips: Enter WBC count in cells/μL and eosinophil percentage (0-100%). Both values must be valid positive numbers with eosinophil percentage between 0-100.
Q1: What is a normal AEC range?
A: Normal AEC typically ranges from 0 to 500 cells/μL. Values above this may indicate eosinophilia.
Q2: Why is AEC important in clinical practice?
A: AEC helps in diagnosing and monitoring conditions like asthma, allergies, parasitic infections, and certain autoimmune disorders more accurately than percentage values alone.
Q3: When should AEC be measured?
A: AEC should be measured when evaluating patients with suspected allergic conditions, parasitic infections, or when monitoring response to treatment in eosinophil-related disorders.
Q4: What conditions cause elevated AEC?
A: Elevated AEC can be caused by allergic reactions, parasitic infections, autoimmune diseases, certain medications, and some types of cancers like eosinophilic leukemia.
Q5: How often should AEC be monitored?
A: Monitoring frequency depends on the underlying condition. For chronic conditions, regular monitoring may be necessary to assess treatment response and disease progression.
