Absolute Eosinophil Count Calculator
Determines the total number of acidophilic cells from white blood cell count and eosinophil percentage.
Refer to the text below the tool for more information about the eosinophil count.
The white blood cell (WBC) count and the eosinophil percentage can be used to estimate the total number of the acidophilic cells in a blood sample.
Eosinophils are involved in immunity response to parasites and are mediators of allergic responses, are used as markers of disease severity, as well as associated with bronchial asthma development.
Absolute Eosinophil Count = WBC x Eosinophils / 100
Parameter | Normal Low | Normal High |
White Blood Cells (WBC) | 4.1 x103/μL | 10.9 x103/μL |
Eosinophils % | 0.1% | 6.0% |
Absolute Eosinophil Count | 0.041 x103/μL | 0.654 x10³/μL |

About Absolute Eosinophil Count
The white blood cell (WBC) count and the eosinophil percentage can be used to estimate the total number of the acidophilic cells in a blood sample.
Eosinophils are granulocytes and generally make up about 1-5 % of the circulating leukocytes. This type of cells is also known as acidophilic because it shows affinity for acids and is full of spherical acidophilic granules. The normal range is between 0.04 and 0.65 x10³/μL.
The function of eosinophils is phagocytosis of antigen-antibody complexes, as well as multiple roles, such as:
- Markers of disease severity;
- Immunity response to parasites;
- Mediators of allergic responses;
- Involvement in bronchial asthma development.
To compute the AEC, a complete blood count test is required, which will reveal the WBC and eosinophil percentage, further used in:
Absolute Eosinophil Count = WBC x Eosinophils / 100
Reference Ranges
Parameter | Normal Low | Normal High |
White Blood Cells (WBC) | 4.1 x103/μL | 10.9 x103/μL |
Eosinophils % | 0.1% | 6.0% |
Absolute Eosinophil Count | 0.041 x103/μL | 0.654 x10³/μL |
Eosinophil Count by Age
Age | AEC |
Neonates | 0 - 0.9 x103/μL |
Infants 1 week to 6 months | 0.2 - 0.3 x103/μL |
Infants, 12 months | 0.3 x103/μL |
Infants, 24 months | 0 - 0.7 x103/μL |
Children | 0 - 0.6 x103/μL |
An abnormal increase in the number of eosinophils is called eosinophilia and may be associated with:
- Allergic and drug reactions;
- Parasitic infestations;
- Some skin disorders;
- Collagen vascular diseases;
- Myeloproliferative diseases;
- Hodgkin’s disease.
An abnormal decrease in the number of eosinophils is called eosinopenia and may be observed in:
- Hyperadrenalism;
- Glucocorticoid administration;
- Acute bacterial infection;
- Physical stress.
Absolute cell counts can be estimated for Neutrophils as well as for Lymphocytes.
