What is the AEC Test?
The AEC test is the Absolute Eosinophil Count: the number of eosinophils, a type of white blood cell, in each microlitre of blood. Eosinophils rise in allergy, asthma, skin conditions and worm infections, so the count helps a doctor see whether an allergic or parasitic cause is likely.
AEC Test normal range
| Measurement | Typical adult value |
|---|---|
| Normal adult range | About 20 to 500 cells per microlitre |
| Mild eosinophilia | About 500 to 1,500 cells per microlitre |
| Moderate eosinophilia | About 1,500 to 5,000 cells per microlitre |
| Severe eosinophilia | Above about 5,000 cells per microlitre |
The AEC is the eosinophil percentage multiplied by the total white cell count, so it can be reported by a counting machine or worked out from a CBC. Labs print slightly different ranges; the range on your own report is the one that applies to you.
Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.
What your AEC Test result means
- High (eosinophilia)
- Often seen with allergy, asthma, eczema and worm infections. Less often it goes with drug reactions or blood and immune conditions. A doctor looks at symptoms and may order stool tests, IgE or a smear to find the cause.
- Normal
- No raised eosinophils. This does not rule out allergy, because many allergic people have a normal count between episodes.
- Low
- Eosinophils can fall during acute infection or stress and with steroid medicines. A low count on its own is rarely a concern.
One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.
Why is the AEC Test done?
- Repeated sneezing, wheeze, cough or breathlessness that may be allergic or asthma
- Itchy skin conditions such as eczema or urticaria
- Suspected worm or other parasite infection
- A high eosinophil percentage on a CBC, to get the actual count
- Monitoring eosinophils in people on certain medicines, as advised by a doctor

The reference interval printed on your actual laboratory report governs interpretation. Intervals can vary by laboratory, method, age, sex and pregnancy. Methods can also vary by processing laboratory.
AEC Test: sample & preparation
Sample: Blood. Fasting: Not required.
- No fasting is required; a blood sample will be drawn from your arm as usual. Tell the technician if you are taking steroids or have any allergies, as these can affect the result.
